You were walking through a park when you stopped at a fountain.

"Let's recap: I can't believe Rias told Issei about that night. Issei is shocked that devils, angels, and fallen angels exist. How could he not? He was killed by one. Rias then had him reincarnated as a devil because she said it was for his safety. She offered to do the same for me, but I declined and insisted that she and her group stay away from Dad. Still, we had talked about it."

(flashback begins)

You are standing outside of the Occult Research Club's room. The doors are still open and you see Issei inside, still a little overwhelmed by everything.

Issei: "This is still a lot to take in."

Koneko: "Don't worry too much, you'll get the hang of it."

Rias then came through the door and walked over to you.

"What do you need?"

Rias: "That fallen angel will come after you. I think it'd be best if you joined my peerage."

"I'll be fine. But look, if it does get bad, then I'll think about it."

Rias sighed.

Rias: "Fine. Just keep that paper you got yesterday. Just think about me and I'll come. By the way, what did your dad shoot at that fallen angel, and how did he heal Issei's wounds? Does he have magic?"

Issei: "No, he's just a really good doctor."

Rias: "I do not doubt that. But still, I think I need to know."

"I'll tell you later."

(flashback ends)

You saw Issei walking with a girl in priestess clothing, and he waved at you.

Issei: "Oh, hey Y/N. Nice to see you here."

"Same. Who's she?"

Issei: "Sit down, and we'll tell you."

"My name is Asia Argento. Nice to meet you."

"I'm Y/N Redgrave. I'm interested in seeing how you two met".

Issei: "I met Asia yesterday and found out how she's being forced to aid the fallen angels. I found her again and we've been having fun for most of the day."

"Sounds like you've had it rough."

Asia: "It's fine. This isn't the first time I was in a bad position."

"What happened before that?"

Asia: "When I was an orphan, I discovered my power to heal. I was worshipped to an extant, but most people saw me as a freak who could heal others, so I hardly had any friends. One day, I came across a hurt man whom I helped heal. Unknown to me, the man was a devil, and I was excommunicated and called a witch. But I still didn't lose faith in God, and dreamt of having many friends."

"I'm sorry, Asia."

Issei: "But I'm your friend now. And so is Y/N."

Asia: "Really?"

"Really. Any friend of Issei is a friend of mine."

Asia cried in joy.

Asia: "Thank you."

Suddenly, you heard splashing in the fountain and turn to see Raynare and a cloaked figure in a skull-like mask.

Raynare: "That girl is my property. And I have unfinished business with both of you. I don't know who the guy who shot me is, but I will find him and kill him. What he shot me with almost caused me to amputate my arm and wing."

Issei: "Get away from them!"

He transformed his left hand into an armored dragon arm.

Raynare: "That's supposed to scare me? What that Sacred Gear does is double the power of its user, and the fact that you're at the level of a human means it does nothing."

You pulled out the gun that Adam gave you and pointed it at Raynare.

"I don't know what those bullets do, but if it ends you, then that's fine with me!"

The cloaked man quickly appeared and threw tranquilizer darts at you, causing you and the others to succumb to the darts and pass out.

Raynare: "Omega..."

When you came to, you found yourself in a strange void again, this time with multiple blocks and energy streams that filled it.

You looked around and saw the encased dragon again.

"Wake up. They're in danger," it said in a female voice.

You woke up and finds yourself, Asia, and Issei chained up and surrounded by a bunch of priests and a few fallen angels.

Raynare: "Finally, you've woken up. The others woke up earlier than you."

"Leave Asia and Issei alone!"

Raynare: "No. Asia's Scared Gear, Healing Twilight, is extremely rare. I must take it for myself. It's far more useful than the one your friend has. I was ordered to kill him because they deemed him a threat. What a joke."

Issei: "Stay away from her."

Raynare: "You can't do anything except maybe watch little Asia die."

You and Issei are horrified by what Raynare said.

Omega: "That is an unfortunate result when one's Sacred Gear is removed from them. Their life is tied to it, so taking it means taking their life."

Raynare: "It's inevitable for her. Her power will cause her to be feared and hated by humans. There's nothing either of you can do about this."

You then had a vision of the encase dragon opening her eyes.

"You want to give up?" she asked. "You want to let your friends die?"

"No."

"Then fight!"

The cage cracked open, and suddenly, you felt a surge of energy. A crown-like helmet formed around your head.

The burst of energy destroyed the chains and filled the room with smoke. Issei's arm transforms as a shockwave emits from his sacred gear.

An invisible being with bladed arms appears from your helmet and starts massacring the priests. Omega and Rayanre start running as the being cuts off her wings and Issei charged at them.

Omega fired a bullet at Issei, but he uses one of the fallen angels as a shield. You and Issei chase Raynare and Omega.

Raynare: "What are you dumbasses waiting for?! Kill them!"

Priests appear and fire at you and Issei, but the being under your command sliced through the bullets and a good amount of the priests. You and Issei deal with some of the remaining priests as your return upstairs.

Issei fired a beam of energy at Raynare and amputates her legs. Raynare falls as Omega jumps to the top of a broken cross, and looks at Issei's Sacred Gear.

Omega: "One of the thirteen Longinus. Gauntlet of the Red Dragon Emperor, Boosted Gear. Doubles your power every ten seconds. Capable of surpassing God himself, but needs time to take effect."

He then looked at your helmet.

Omega: "The Crown of Dominion. Hidden from existence itself, unless our beloved deems someone worthy. You have been deemed worthy of its power."

Raynare: "What are you doing?! Help me!"

Omega: "You let your guard down and your arrogance got the best of you. You are already dead."

Omega looked at you and Issei.

Omega: "This isn't the last you've seen of me. Or the others."

Issei: "We'll take on you and the three factions if they try to harm us."

Omega: "My order is not with the three factions."

Omega disappeared and Issei turned to Raynare.

Raynare: "Stay away from me!"

She threw a spear of light at Issei, but he deflected it. Something grew in Issei as he doesn't hold back his hatred. He grabs Raynare's head, picks her up, and crushes it.

As Issei drops Raynare's carcass, Asia comes up and sees the scene. Issei looked up in shock at what he did as the hatred fades away.

Issei: "What am I?"

"You are Issei Hyoudou, my best friend."

Asia walks to Issei and embraces him.

Asia: "And you're my friend too."

Issei began to cry.

Issei: "Thank you both."

Rias and the others enter the church and noticed all the carnage.

Rias: "I'd yell at you for doing something extremely reckless, but I'm guessing you two got kidnapped?"

"Yeah."

Asia: "It's not their fault."

Rias: "I know it's not."

Issei: "Rias... I want to protect Asia."

Rias: "I know."

She pulled out a Bishop chess piece.

Rias: "Will you join us, Asia Argento?"

Asia: "Yes."

The next day, you are in the Occult Research Club, having joined because of Rias' insistence. You sat down as he sees Issei and the others celebrating Asia's arrival.

Rias: "You're happy for him, aren't you?"

"How could I not? I still don't fully trust the Supernatural, but I can tell that you guys are alright."

Rias: "Thank you. And let me tell you something interesting. When a human is reincarnated as a devil, the number of Evil Pieces consumed depends on their abilities. I used all eight on him because that's how many he needed. Issei has extraordinary potential, and your sacred gear is something I'm still trying to find out about. Just stick with us and we can figure it out together."

"Okay, sure."

Rias smiled and the two of you joined the others.
