"It's been a while hasn't it Kuroka" Kitomi look at her fellow Nekomata, the black haired didn't reply and takes her stance "Why do you look so serious?" Kitomi smirk "I'm tired of hearing you talk" Kuroka state and dash toward the silver haired.

Kuroka throws a punch which Kitomi catches and grab her wrist tightly, the black haired clench her right hand throws it which the silver haired also catch, the two glares at each other as the whole field begin to shake from the two releasing their power pushing each other back.

"What happen with saying Nya seems like you never say it when you're with me" the silver haired grins making purple aura surrounds Kuroka she pushes the silver haired back and kicks in the stomach sending her back.

Kuroka lift her right hand creating a yellow orb on her palm, she aims at the silver haired and fires a giant yellow energy beam.

Kitomi snaps her eyes open and place a right hand on the ground to push herself up to the air narrowly dodging the energy beam, the beam hit the trees and explode. Kitomi look at the black haired and speed down toward her, lifting a right hand.

Kuroka raise her hand up blocking the attack the ground imploded from the shockwave of the attack, Kitomi suddenly disappears and reappear behind Kuroka to deliver a kick but as the kick about to connect the black haired disappear.

Kitomi eyes widen when she is suddenly kick in the chin from Kuroka who appears right in front, the silver haired is send up to the air. Kuroka jumps up and appears in front of Kitomi. "Hmm it seems I need to finish this quickly" Kitomi snap her eyes open showing the black haired her now blood red slit eyes.

Before she could reach Kuroka is punch in the stomach knocking the wind out of her. Kitomi flip to the side and slam her fist down on the black haired stomach again sending her deeper down from the air as the two are near the ground, Kitomi spins and slam her foot down on Kuroka stomach sending her crashing to the ground hard creating a wide crater.

Kitomi front flip and land on the ground gently, when the dust clear she sees Kuroka getting out of the crater but falls to the knees holding her stomach as blood sip from her mouth.

"Sorry Kuroka but you won't be killing me today and an advice that boy you trying to protect is going to be in danger especially with my partner being his opponent" Kitomi puts her hood back on and disappears in white flames.

Kuruka curse silently standing up wobbly "Damn it I won't be able to do much in this current state Nya" She mutters and dash away from the area.

Occult Club

Issei body froze in shock and fear seeing the violet slit eyes staring down at his form like some kind of insect that can be crush with ease "Issei Hyoudou your coming with me" She state as the brown haired feel the enormous power coming from the person in front of him.

'How did I not sense this she's was just outside?!' Issei yell mentally 'It's seems she is hiding her power but when you're near her you can sense it... Partner retreat now this person in front of you is easily in ultimate class level, probably even higher' Ddraig advise shocking the brown haired.

"W-who are y-you?" Issei ask in a nervous tone the unnamed girl ignore the question and bring her hand out from the cloak showing her nails are painted black she was about to grab Issei, when six light beam slams into her midsection freezing her.

Nawin appears in front of them and grab Issei shoulder the two disappears in black flash to reappear a few meters away from the mysterious enemy. "T-teme" Issei stutters in shock but also relief, Nawin turns to him "Issei you alright?" he ask making the brown haired nod.

Nawin turn his attention back to the girl dark yellow aura forms around her making the light beam shatters freeing herself. She turns to the two "Seems like you arrived I was hoping that you wouldn't come here Nawin-kun" She said.

Suddenly dozen of shadow weapons appear surrounding the Makasha, "Issei stay back" He order. Nawin raise his right hand up and twirls his finger making the weapons spins around him, Nawin holds his left hand out and grab the great sword then appears behind the Akumi member, holding both his hand on the grip tightly and swings the great sword down with huge force but the girl summons a yellow light lance and lift it up blocking the attack with ease. Nawin remove his left hand from the grip to summons another great sword, he grips it tightly and slam it down to the light lance making it creak.

The ground beneath the cloak girl rumbles from the force that is pushing her, the girl summons a light sword in her left hand slash the great swords in half shattering it into pieces while also sending Nawin back slamming into a tree.

Nawin push himself out of the tree and opens his eyes to see Issei dashing toward the Akumi member making his eyes widen "Issei stop!". The Hyoudou jumps up and summons his sacred gear, "BOOST, BOOST, BOOST, BOOST" He slams it down but the girl raises her light lance blocking it with ease, she grips the lance tightly and push it to the side making Issei lose his balance in mid air.

The girl strike her sword through Issei stomach making him throw up blood feeling the burning pain in his stomach. Nawin eyes turn blood red and appears behind the girl to kick the girl in the side sending her away.

Nawin catch Issei before he falls to the ground and yank the light sword away crushing it "You moron I told you not to engage her" Nawin said looking at the pervert "Ahaha yeah sorry but I just wanted to help" Issei chuckle weakly.

Nawin turns to see the girl getting back up in her feet and dusts the cloak before making her way to the two "I suggest you stop fighting Nawin-kun and hand Issei Hyoudou over to me" She warn stopping a few meter away from them.

"Over my dead body" Nawin appears in front of her and strike his right fist forward making the girl lift her right hand catching it. Nawin jumps and swings his left feet toward her side but she also blocks it with her other hand. Nawin smirk and use his left hand and pull her hood down.

What the Makasha saw shock him to the core "W-who are you" He mutters seeing a girl who look almost identical to Akeno the only different he can spot is her slit eyes and her hair which is dark brown shorter that is tied into a pony tail. Suddenly dozen of blurry image hits Nawin mind making him flinch.

The brown haired use this time and kick the black haired in the stomach sending him crashing to the ground. Nawin clench his stomach as blood sip from his mouth, he stands back up shakily and looks at the girl "W-who are you?" The brown haired didn't reply and only looks at him with those emotionless eyes.

Kitomi suddenly appear beside her partner "Hmm I see you are taking your time with this should we take him now?" she ask looking at Issei "...No I sense some energy signature coming this way and two of them are Satan class" the brown haired reply pulling her hood back on.

The brown haired flick her finger summoning a black portal behind them "Wait!!" Nawin yells making the two turn to him "Tell me who are you?!" He asks "Sorry Nawin-kun but this is not the right time" The Makasha glares at her. He suddenly dashes toward the brown haired and summons Demonic lighting at his right hand as the mark glows purple.

The brown haired sees the mark making her eyes narrow 'Draconic Mark...' purple aura surrounds Nawin, "AHHHHHHHH" He yells striking the demonic lighting toward the Akumi member.

The brown haired grab Nawin right writs in lighting speed and slap it to the side redirecting it away from her creating an explosion. Issei gets on his feet and looks up to see the brown haired gripping Nawin wrist tightly while her left hand holds his neck lifting him up in the air.

She tightens her grip on the black haired wrist making him scream in pain, "Teme!" Issei yells he was about to run toward his friend but Kitomi snap her finger making white flames surrounds him. Nawin opens his eyes weakly making his red eyes meets the brown haired violet slit eyes.

"You're too weak" She state and release his wrist to slams her right fist at the black haired stomach sending him crashing to the occult building.

"We should go" Kitomi suggest as the brown haired stare at Nawin for a few seconds then nods. The two walks in to the portal making it close white flames disappears freeing Issei and he immediately dash toward the fallen Makasha "Nawin you alright?" He yells lifting the black haired up and lean him against the occult building.

Issei sees the black haired is unconscious "Damn it" he curses and looks back at where the Akumi member used to be 'Who is she and why does she look almost identical to Akeno-sempai'.

Suddenly the Gremory symbol appears making Issei turn to see Rias, Sirzech, and Grayfia arrive. A black cat with yellow slit eyes looks at the Makasha from the tree before dashing away

Time Skip

It's been 3 hours since the incident currently Rias and her peerage are in the Gremory estate with Lord Gremory, Velenana, Sirzech, Grayfia and Azazel. All of them are sitting at the living room ready to hear what happen this afternoon from Issei and Nawin who just woken up.

As everyone is seated they quickly notice that Nawin is staring blankly down at the table like his in a trance. Azazel eyes narrow seeing this "Nawin" he said snapping the black haired back, Nawin shakes his head and turn to his godfather "Sorry I'm just... a little tired".

"Since everyone is here, I would like to know what happen earlier" Sirzech begins, he turns to the Nawin and Issei "You two mind explaining what happen and tell us the full details, this morning two Ultimate class level enemies just slip through Kuoh completely undetected which is a problem and I like to know how they did that" Sirzech turns to the Makasha "Nawin-kun you were the first person to notice them, tell us what happen".

"When I was on my date with Akeno this two individual walk in a restaurant wearing a long, dark cloak with red roses" Azazel eyes widen hearing this along with Sirzech, and Grayfia "I know something was suspicious about them since they wore a hood covering their faces and when they walk pass our table I sense their enormous power for a second" Nawin said.

"I didn't sense anything when they walk pass us Nawin-kun" Akeno said confuse "They are able to hide their energy somehow, very well matter of fact that makes us think their just normal humans" the black haired reply.

"So I send my familiar to follow them while I take Akeno home considering I don't want her in this, if it turns into a battle" Akeno look conflicted on the idea but she kept quiet.

"The two notice my familiar following them so they lead her away from Kuoh to an isolated location. After taking Akeno home I teleport there and engage in battle with them" "Who are they?" Sirzech ask "One of them is a double S class Criminal, her name is Kitomi Zetsumi" he said shocking them, "And the other one" Azazel ask.

Issei opens his mouth but shut it, remembering what happen 10 minute ago.

Flashback

Nawin sits on the bed with the other members in the room waiting Sirzech and Grayfia to arrive since they suddenly left after bringing Nawin and Issei to the estate "Hey guys do you mind I talk to Issei in private for a minute" He say making Rias and the others look at him confuse but nod anyway.

When the group left, Nawin turns to the brown haired "Issei in the meeting I don't want you to mentioned the other girl" He said shocking the brown haired "But why I mean they should know, someone is walking out there who looks identical to Akeno-sempai" Issei reply.

"I know that but... we know next to nothing about her, we will tell them when it's the right time, I should research about her and see if Akeno have any other relatives, telling them right now won't do any good and if Akeno hears about this we don't know what she will do.... Understand" Issei opens his mouth but close it and nods "Alright I won't mention her at the meeting"

Present

Nawin glance at Issei for minute then turns back to Azazel "The other individual didn't show their face, so we couldn't identify her" He reply making them nod.

"But I'm sure you all know who there are right" Nawin said looking at Sirzech, Grayfia and Azazel "What do you mean Nawin-kun" Rias ask confuse along with the other "Huh there's been a mysterious group roaming around the underworld and the human world wearing long, black cloak with red roses" "They call themselves Akumi" Azazel said.

"Evil Beauty" Venelana said hearing the name "Interesting name for an organization" Lord Gremory says "We don't know what their goals are but I do know one thing, they are after Issei" Nawin said making them turn to the brown haired.

"How do you know this Nawin-kun" Xenovia ask "While I was fighting Kitomi, the other member went after Issei, when I was fighting a losing match, another double S class criminal appear saving me" He said shocking everyone "Which I found weird considering, I thought Akumi is an organization full of Double S class criminal from what I heard" "Who is the one that save you?" Grayfia ask.

"A stray devil name Kuroka" He answer shocking others, Koneko eyes widen hearing the name, Rias notice this and pets her head calming the white haired down. "Why did she save you?" Azazel asks "I don't know, she said we can't have you dying on us just yet, I'm not sure what that means" Nawin reply.

Sirzech leans back in his chair and sigh "This is a problem, those two Akumi member are powerful that only Ultimate class level or Satan class can go match to match with them if the-" Nawin cuts in "I don't think Issei is their only objective in this, something tells me there's more but we know very little about them still" He said making the red haired nod.

"I don't think they will make much move anymore, well until the future" Azazel said making everyone turn to him "This is probably just a part of their plan making themselves known and that their dangerous" he said "True but when I told them that their Akumi, Kitomi turned serious and almost finish me until I was saved" Nawin reply.

Lord Gremory cross his arms "I heard about these cloak people going around the underworld but I didn't know it will be like this" "We kept it a secret so there wouldn't be panic but if they make themselves known again I think I will have to alert this to the Royal clans and the whole underworld about this to keep their guard up and alert the Satan's if the Akumi are spotted" Sirzech says.

"I have kept my eyes on them for a while with my spies around the world looking out for them, they have been spotted here and there but only doing things like bounty hunting and such, I will alert this to the rest of the Grigori" Azazel said.

"I suggest you don't alert the people about this just yet" Nawin said making them turn to him "They haven't make themselves known that much this attack is only known by the people in this room, I'm sure allot of people won't know about this and probably won't take it to heart until the Akumi really do strike something big that will catch the people's attention" "What is your plan then Nawin-kun?" Sirzech ask.

"We shouldn't act hasty for now we should keep our eyes on them alerting everyone will cause more trouble then it's worth, I'm sure you Sirzech have spies around the underworld, if they catch sight of them then make them follow the Akumi member and maybe we can learn something and get their identities or what's their main goal is" He said.

Sirzech thinks about this and nods "Huh looks like you do use your brain sometimes kid" Azazel chuckle making Nawin glare at him. "Okay I say that's enough for this meeting I will go talk to the other Satan's about this since it will make things easier and we can spread our spies around the underworld wider with their help" Sirzech said making Azazel nods "My spies will remain in the human world considering their also been spotted there too".

"Onii-sama what should we do?" Rias ask her brother "For know Rias you should continue to do what you usually do, the observation day will come next week on Friday right" Rias nods "Good, I forgot to tell you this but there's actually a summit being held on Saturday in Kuoh for the peace treaties on the 3 fraction" Sirzech said "Peace treaties?" Nawin ask.

"Every 3 years there will be a summit for the 3 fraction leaders to meet each other and discuss boring things" Azazel sigh lazily, he hates these meeting since it's always boring, Sirzech chuckle at the Fallen angel laziness "I think that might also be a good time to inform the angels about the Akumi, maybe they can help us in the future against them" He said.

"Onii-chan what was it like battling against a powerful opponents" Asia ask curious while the others attention. "Asia-chan I can tell you that" Issei said making the blonde turn to him.

"Don't listen to him Asia it probably goes like this, when Nawin-kun is battling the Akumi member, Issei stood there and watch the battle like an idiot, already injured and defeated" Xenovia said blankly "Hey I did fight them, I was like cha and hyo" Issei start making some stupid fighting stance "And then you got stab, I saw your wounds" Xenovia reply making Issei floor palms, the others laugh.

While the group laughs, Nawin clench his fist 'You're too weak' he place his left hand over the mark, it flashes purple 'If you want more power, you will come to me' the voice whisper.

Time Skip

Nawin and Akeno are currently walking home with Asia sleeping on Nawin back considering it's already late. Akeno glance at the black haired worry, ever since they left the Gremory estate he's been quiet, well more quiet than usual "Nawin-kun is something on your mind" She ask making the black haired turn to her.

Looking at Akeno face the brown haired girl image appears over Akeno face making Nawin eyes widen, blurry images speeds through his mind making the black haired stop. Nawin shakes his head, clearing his mind "Yeah I'm fine Akeno I'm just tired with everything that's happened today" he said resume walking Akeno nods following beside him.
