(Old School Building)

(Occult Research Club Room)

Issei: W-What is this room?

Y/N: It looks so... neat and... quiet.

Y/N and Issei then looked at Koneko sitting on the couch while eating chocolate.

Issei: T-That girl is...

Y/N: She's here, too?

Yuuto: She's Koneko Toujou-san, a first-year student.

Koneko looks at them as Yuuto introduces Y/N and Issei.

Yuuto: This is Issei Hyoudou-kun and I know you've already met Y/N Kenzaki-kun.

Issei: Oh, nice to meet you.

Koneko: Umu.

Koneko looks at Y/N.

Koneko: It's nice to see you again, Kenzaki-sempai.

Y/N: Yeah, same here, Toujou-san.

?????: Ara ara~.

Y/N: Hm?

Y/N turns to see Akeno standing by the mini shower room.

Akeno: Ara ara~. Look who's here.

Y/N: You're...

Akeno giggles as she starts walking towards Y/N and Issei.

Akeno: *smiles* You two are the new club members, right? *bows* Pleased to meet you. I'm the club's vice president, Akeno Himejima. Pleased to make your acquaintance.

Issei: *blushes* I-I'm Issei Hyoudou. Nice to meet you, too.

Akeno turns to Y/N.

Akeno: Ara ara~. It's finally good to see you again, Kenzaki-kun. I want to properly thank you for what you did for me and saving me back then. I really appreciate it.

Y/N: *smiles* It's nice to see you too, Himejima-sempai. It's no problem, actually. It's always my hobby to help everyone, really.

????: Thanks for waiting.

Rias then comes out of the mini shower room and was all dressed after she took a shower.

Rias: Sorry, I spent the night at your place, so I had to...

Issei: O-Oh no, I don't mind at all.

Rias: Well, everyone's here now.

Then everyone takes their seats on couches and Rias was standing in front of them.

Rias: We welcome you to the Occult Research Club. But, the Occult Research Club is a mere facade. Nothing more than a hobby.

Y/N: I see.

Issei: What do you mean?

Rias: I'll be frank... We are demons.

Y/N: Wait... you're not lying, are you?

Rias: No. I'm serious.

Issei: T-That was indeed very frank.

Rias: The black-winged man you saw yesterday... was a fallen angel.

Issei: ?!

Y/N: Fallen angel...? 

Rias: Once angels serving God, they have been cast down to the underworld due to their wicked nature. They're trying to manipulate humans and destroy us demons. Since primeval times, there's been a constant struggle for dominance in the underworld, or Hell, as humans call it. There are also normal angels, coming here on God's orders to hunt demons. In other words, we have a three-way standoff.

Y/N: I see now...

Issei: *sweatdrops* Uh... 

Rias: Do you follow me so far?

Issei: Um, this is getting kinda too complicated for a stupid high school student like me.

Y/N: The reason why you're not getting all of this is because your brain is stupid.

Issei: *looks at Y/N* What the hell did you say, Kenzaki?!?! Your brain is the stupid one here!

Y/N: *looks at Issei* Huh?!?! What are you talking about?! My grades are better than yours! You are no match for my knowledge!

Issei: Why you...!

Rias: That's enough, you two. As I was saying... Issei... Do you still remember Yuuma Amano?

Issei: What...?

Rias: *looks at Issei* I'm sure you remember her. You even had a date, after all. 

Issei: I-I have no idea where you've heard that name, but don't treat it as some occult phenomenon. Frankly speaking, I find it unpleasant. Sorry, but...

Rias pulls out a picture from her pocket and shows Issei the picture of him and Yuuma on a date.

Issei: Yuuma-chan...?

Rias: She was there. No doubt about it. This girl is Yuuma Amano, isn't she?

Issei: Y-Yes, but how did you get this? 

Rias: This girl... No, this fallen angel. It's the same faction that assaulted you last night.

Issei: B-But Matsuda and Motohama didn't remember anything about her and her cellphone address also...

 Rias: She used her powers... just like I used mine on your parents.

Issei then remembers back in the morning that he was having breakfast with her and his parents when Rias explained to her parents the situation using her powers.

Rias: Once that fallen angel completed her mission, she erased memories and records of it from you and the people around you.

Issei: Mission?

Rias: By killing you. She came to check whether you have a dangerous object in your body. You were killed once that was confirmed. Impaled by a light-lance, to be precise. 

Issei: Now I remember. Yuuma-chan talked about a Sa-something. 

Rias: Sacred Gear. 

Akeno: An unusual power that resides in certain humans. It is said most of the great men in history possessed it.

 Rias: Sometimes they have power formidable enough to threaten demons and fallen angels. Issei, raise your left hand. 

Issei raises his left hand.

Issei: Like this?

Rias: Close your eyes and imagine the strongest being that comes to mind.

Issei: T-This is all too sudden...

Rias: Focus, Issei.

Issei: R-Right! Focus, focus... Oh!

Issei tried to focus, but he was distracted by looking at Rias' panties.

Rias: Yes, Issei, focus.

Issei: Focus, focus...focus... Foc-! Argh!!! I can't do it! 

Rias: It's all right. We'll take it slow.

Inner Issei: My focus keeps shifting because I can see your panties!

Issei: Still, maybe there's been some kind of mistake. 

Rias: It's a fact the fallen angels fear it and had you killed.

Issei: But it's a fact, how come I'm actually alive?

Rias: Because of this.

Rias picks up the flyer and shows it to Issei.

Issei: T-That is...

Rias: You summoned me from this flyer moments before you died. 

Inner Issei: Oh yeah, that time I remembered Rias-senpai's hair and Kenzaki trying to save me...

Rias: Issei, you've been reborn into the household of Rias Gremory, daughter of Duke Gremory, an upper-class demon. 

Rias then spreads her demon wings out from her back.

Rias: As my servant, that is!

Akeno: Indeed, we're the same.

Akeno, Koneko, and Kiba followed as they show their demon wings to Issei and Y/N.

Y/N: Whoa... That's awesome.

Issei: W-What...?!

Issei then felt something appeared coming out from his back as he turns around and sees that he also has demon wings.

Rias: So, welcome, Issei.

Y/N: I knew it... Rias-senpai really brought back Issei as a demon...

Inner Issei: Seriously? I'm a demon? I'm no longer human?... Wait... What about Kenzaki?

Issei: I-I'm starting to understand what's really going on here, but... I still don't know why Kenzaki has to be here.

Y/N: Finally! Someone finally got my attention! Damn, I had to wait for you guys to tell me why I was asked to come here.

Akeno: Ara ara~. How could I forget my hero~? That's really rude of us.

Rias: My apologies, Kenzaki-kun. I was only trying to explain to your friend the situation here.

Y/N: I understand what's really going on here, but... what does this all have to do with me?

Rias: That's a good question... The real reason you're here... is that we need to warn you about that device you had.

Y/N: The device I had...?

Rias: Your Sacred Gear. The belt and the cards.

Y/N: My belt and cards...

Y/N pulls out his spade ace card and his Blay Buckle.

Y/N: You mean these?

Akeno, Kiba, and Koneko were shocked when they looked at the Buckle and the Spade Ace card.

Kiba: I-I can't believe it... It's real...?

Akeno: Ara ara... So the legends are true...

Koneko: ...

Rias: Would you mind if I take a look at them?

Y/N: Eh? U-Uh, sure.

Y/N then hands the buckle and the card over to Rias.

Rias: It is real... It's not a fake. I thought the belt and the cards were just a myth from my father's story.

Y/N: Look, I don't know why you are all stunned at looking at them, but I need answers. What is this belt? What's with the cards I had? And how did I get them in the first place?

Rias: ... I suppose it would be fair to tell you if you already had these.

Rias puts down the belt and the card and then everyone sits down.

Rias: This is a story my father told me when I was young. Before the three-way standoff started I mentioned earlier, God created the most dangerous beings called the "Undead" and started a battle royale tournament called the "Battle Fight" for the Undead to fight and kill each other.

Y/N: Undead?

Issei: Battle Fight?

Rias: The Battle Fight was a free-for-all battle royal which was started before the three-way standoff when God created the Undead in the form of a stone slab called Monolith, to kill each other in the Battle Fight. Whatever Undead wins the tournament will be granted a wish to alter the world. There were 52 Undead representing 52 different species and battled so they can wish for the species they represent to rule Earth while the Joker represents Death.

Y/N: The Joker Undead? Wait, if the Joker represents Death, what will happen if the Joker wins the tournament?

Rias: If all of the undead will be eliminated from the tournament, and if the Joker will be the last Undead left... the world will be destroyed.

Y/N: What...?!

Issei: The world will be destroyed?! B-But the Joker didn't win, right?

Rias: That's right. The Joker Undead was defeated. The one who won the Battle Fight... was the Human Undead. After the Human Undead won the Battle Fight, the world has been populated by humans ever since. 

Issei: No way... The one who created humans is...

Y/N: So it's the Human Undead who won the Battle Fight and populate the world with humans, huh? Now that's interesting. 

Issei: So, what happened to Human Undead? Where did he go?

Rias: No one knows. The story tells that after the Human Undead won the Battle Fight, the Human Undead decided to wander around the world to find what his dream was, hiding his true identity to everyone, and he was never found ever again. After the Battle Fight ended, God had gathered all of the defeated and sealed Undead back to heaven and created the most powerful Sacred Gears that has the power to destroy all angels, fallen angels, and demons, including the gods... The Sacred Buckles. *looks at Y/N* And you, Y/N Kenzaki-kun had possessed one of the Sacred Buckles.

Y/N: Me...? All this time... I've been holding the most dangerous weapon that has the power destroy all angels, fallen angels, demons, gods?! 

Rias: I'm afraid so.

Y/N: I... I don't believe it...

Akeno: We are stunned about this too, Kenzaki-kun.

Kiba: I thought the story of the Battle Fight of the Undead and the Sacred Buckles was just a myth, but... I never knew the story and the buckles would be real...

Rias: The Sacred Buckles were the first four Sacred Gears created by God, and they have a system that controls and use the powers of the sealed Undead inside the cards. God created four Buckles and had named one for each of them... The Warrior of the Lightning Spade, Blade, the Warrior of the Burning Diamond, Garren, the Warrior of the Hurricane Heart, Chalice, and the Warrior of the Frozen Club, Leangle.

Y/N: Blade...? Did you just say Blade?

Rias: That's right. You are the Warrior of the Lightning Spade, Blade. Why do you ask?

Y/N: I was having these weird dreams in my sleep. In my dreams, there was a guy wearing white clothing always kept talking to me that I will be the hero this world needs. He always told me this before I wake up... "I'll be waiting for you and keep getting stronger... Blade".  That's what he said. That's why I kept remembering the name and call myself "Blade" every time I transform in dangerous situations.

Akeno: He said that?

Kiba: Do you know who he is?

Y/N: Sorry, I don't really remember much in my sleep.

Rias: I see. So that's how you heard of the name. By the way, Kenzaki-kun, how did you even summon your Sacred Gear without any assistance in the first place?

Y/N: Well... I don't really remember, but I can tell you another time if that's fine with you.

Rias: Is that so? Well, I guess we can wait until you are ready to tell.

Y/N: Thank you.

Rias: Also, there's one thing I need to ask you, Kenzaki-kun.

Y/N: What is it?

Rias: I'll ask one more time... Will you join in the Gremory household?

Y/N: ...

Rias: I have already brought your best friend back to life because I needed him to be part of my family and make him grow stronger with his Sacred Gear, but he hasn't summoned it yet, so it will take some time. So let me ask you again, Kenzaki-kun... will you come and join in my household?

Y/N: ... I'm sorry, Rias-senpai. I can't join you.

Issei: Kenzaki...?

Rias: Why?

Y/N: Because I have a dream I must achieve in my life. 

Rias: Really?

Akeno: What's your dream?

Y/N: My dream... is to become a real hero to the whole city.

Rias/Akeno/Kiba/Koneko: A hero...?

Y/N: *smiles* That's right. I've always wanted to be a hero ever since I was a kid. A hero who always saves and protects everyone who cannot protect themselves. And that kind of hero... is a Kamen Rider. That's the kind of hero I want to be.

Rias: A Kamen Rider...?

Y/N: Ever since I got this belt and the cards and transformed into Blade three years ago, I've been doing things like a hero no one has ever done, stopping crimes and thieves, saving people from a fire, or even saving a cat from a tree.

Akeno: ...*smiles* You really are something, Kenzaki-kun.

Kiba: A hero, huh? I can't remember the last time I heard that word.

Koneko: A hero... That's not so bad.

Y/N: That's why I can't join your household and become a demon, Rias-senpai. *bows* I'm really sorry.

Rias: *smiles* Is that so? If that's what you decided, then we won't stop you. We understand. But are you sure? We can still help you train and learn more about your Sacred Gear.

Y/N: I'm sure. I'll let you know if I need any help.

Rias: I see.

Y/N: I can't join your household and become your demon servant... But I can help you with your missions if you needed my help.

Rias: I really appreciate your help, Kenzaki-kun. I'll let you know.

Y/N: *smiles* Okay, then.

Y/N stands up.

Y/N: Well, it's nice meeting you all. I'll take my leave, then. I'll see you all tomorrow at school.

Rias: Take care of yourself.

Y/N: Then please excuse me.

Y/N then walks out of the Occult Research Club.

Issei: H-Hey, Rias-senpai. Are you sure you want to let him go? He has a Sacred Gear and he needs to learn more about it and train. We don't know when those Fallen Angels will show up and attack him. And there's a possibility that he'll never come back.

Rias: Don't worry, Issei. Your best friend is strong. I believe in him. If that's what he wants, then it's fine. We'll always welcome him back to the household if he ever makes up his mind. *looks at Issei* And you heard what he said... *smiles* He's a hero and a Kamen Rider, after all.

Issei: Rias-senpai...
