Later that night, Jirou and Kotaro went to the OCC building.
"Big brother, what are we doing here?" asked Kotaro as they walked into the building's lobby.
"Looks like you haven't told him either," said Mimiko who was standing with Kain, Sei, Zelman, and Mina to their side.
"What are you all doing here?!" asked a mad Jirou.
"The four of them are to go with you, Jirou," said Sei as he stepped forwards.
"No way, this is to dangers for them, especially that little girl," said Jirou as he pointed at Mina.
"Uh, big brother you really don't want to make her mad," said Kotaro with a worried face.
"And why's that?" asked Jirou. All of a sudden, Mina appeared before Jirou and pushed him, sending him flying into a nearby wall.
"She's strong for her age," said Kotaro with a beat of sweat on the side of his face.
"Alright, they can come along," said Jirou as he fell off the wall.
"Good, now fallow me," said Sei as he lead them into a stair way that was behind a door, which was hidden by a giant painting.
"Hey big brother, what did Mimiko mean when she said that you hadn't told me something?" asked Kotaro as he walked beside Jirou.
"Don't worry about that right now, Kotaro," said Jirou with a series face. When they reached the bottom of the steps they found two giant doors before them.
"The locks look pretty tough, got a giant key for them?" asked Zelmon as he noticed the giant locks on the doors.
"The only thing that can open the doors is the truth, and Jirou knows what truth that is," said Sei.
"The truth is about who Kotaro is," said Jirou.
"What do you mean big brother?" asked Kotaro with a confused face.
"You're not really my little brother, you're actually the reincarnation of Alice Eve, the old blood who turned me," said Jirou. Everyone had shocked faces at this turn of events, except for Kotaro.
"I already knew that," said Kotaro. This just shocked everyone even more, including Jirou.
"Yo, you already knew?!" said Jirou in a shocked and mad voice.
"Yeah I did, I have actually known for a while now, ever since I turned five I have been able to see parts of my past life," said Kotaro.
"You little," said Jirou as he punched Kotaro on the head.
"Ow, what was that for?" asked Kotaro as he grabbed his head.
"If you had told me that sooner then I wouldn't have been so worried to tell you!" said Jirou.
"I'm sorry big brother," said Kotaro who was about to cry. The doors then opened and let a black smoke out into the room.
"That's some dark aura," said Mina.
"Everyone please be careful in there, it is a dangerous place filled with all kinds of evil," said Sei.
"We will Sir," said Mimiko. The group then walked through the door way into the 13th yard.
