Yukio stood in front of his brother's grave.

Rin Okumura

Loyal friend and brother

The tombstone read. Kuro sat in front of it and nuzzled the grey stone lovingly and sadly. Yukio clenched Kurikara's red cover. He had the sword put in the coffin, but he kept the case. He stood there for a long time, just starring. Eventually, someone else showed up.

"It's a shame, really. He could've done so much, and it's all because they felt the need to get rid of him that he's in the place he's in." Mephisto said.

"What do you mean?" Yukio asked. Mephsito giggled a bit.

"I really shouldn't say, you could destroy the universe as we know it if you did something about it...but it would be rather interesting..." The older demon said. Yukio was slowly losing patience with him.

"Come with me, have you ever heard of a place called purgatory?"

"Purgatory? Isn't that the place between earth and heaven?"

"Kind of. It most certanly exists, but instead of that it's more of a place for teens and older children that lived unfulfilled lives to fulfill them before passing on."

"Are you saying that Rin went there?"

"No, I'm saying that it's a possibility. Although, if he did go there then there's a strong possibility that he can't remember anything."

"How do I get there?" Mephisto began laughing hysterically at Yukio's question.

"I thought I told you. To get there you have to die. No living person has ever made it there. I can only think of one way for you to get there without dying, but that could very well cause the destruction of the universe and distortion of the life and death cycle."

"I don't care, I have to try." Mephisto sighed.

"I should be able to create a door there, but it'll take a few days."

"Why are you helping me?"

"Because Rin could've done so much, given the chance. I feel bad for him, this is the least I can do."

Elsewhere...

"I just have to think about what I want to make, right?" Rin asked.

"Yep, although we could just make something for you."

"I have to do this, I don't know why, but I have to." Rin said. He looked at the pile of dirt in front of him and closed his eyes. A faint blue glow emited from the pile and a red cased sword began emerging. Two small blue horns made of fire appeared on his head.

"Is that supposed to happen?!" Otonashi asked.

"No, it isn't! Rin, what the heck is going on?!" Yuri asked as the sword finished and the flames vanished.

"What do you mean?" Rin asked, as he hadn't seen the flames.

"Blue flames just appeared on your head, you're wearing odd cosplay items, and I just get this odd feeling around you. Who are you?"

"I don't know!"

"Anyway, is that a katana? Could I see?" Yuri asked

"Sorry, but I remember that I can't show it to anyone."

"I understand."

A bit later...

Yukio walked into Mephisto's office and closed the door behind himself.

"Is it ready?"

"Yes. Listen carefully, I can only keep the door open for three days and I have no idea what's out there, be careful because you might get trapped there and cause the destruction of the universe. Good luck~!" Mephisto said before opening a portal beneath Yukio. He fell in only thinking one thing.

I'm coming for you Rin.
