8 Months ago...The building was caught on fire. A group of people is standing outside calling for help.

"The fire is spreading!"

"Someone call the Fire Department!"

Then there is an explosion.

"Whoa!" A long brown-haired boy around at age of 17, was sitting on a train, heavily breathing. "What a nightmare."

"You got it too, Aki?"

Aki turns to a light-blue-haired boy with red eyes who was sitting beside him. "Wait! You got it too, Yuki?"

"Not just me, but Tomo also has it." As he points to a purple-haired boy around the same age as Aki and Yuki, who is sitting across, sleeping comfortably. "He just had it this morning."

"What about you Seth?" As Aki turns to a man with long silver hair who was sleeping with Tomo.

Seth then wakes up. "Oh...How did you know that I was awake?"

" I just saw you moved, a moment ago."

"Eh? Oh well...Looks like we're in this together, huh?"

"What do you mean?" As Yuki looks at Seth with his eyes widened. "Don't tell me that Kazuya and Kite also has it?"

Seth then turns to the two little kids around at age of 11 or 12, who was sitting at the other side. They both have short blue hair, almost identical to each other like twins. Kazuya who now wakes up from his sleep. Kite, the tomboyish girl who is already up, staring at the window.

"I wonder if it's the sign." As Kite continues to stare at the window. "Something big is about to happen in Tokyo."

Kazuya then replies, "Well, all of our memories have erased. Maybe, that burning building is the cause of that."

"Well, we should be arriving at Tokyo any minute now." As Aki checks his watch. Then he turns to Seth. "Where we are staying at?"

"Haido Hotel." Seth smiled.

Yuki is shocked. "Oi oi! Isn't that the building that was on fire few months ago?"

"Yes, but not the same one we had in our nightmare. I did some research. The cause of that fire was a lit cigarette. Two people were killed during that fire."

Aki smiled. "And I assumed that Haido Hotel is the safest place to live at?"

"We faced danger before, haven't we?" Said Kazuya, with his arms folded. "Sounds pretty interesting to me, though."

Kite looks at Kazuya and smiles. "A journey is a start of someone's life. Every story has a different end."

"Eh?" Kazuya with confused look.

Kite giggled and then she explains, "What I meant was, we're on a same journey. Our story has a different end. Our memories will be restored. Or our lives will end."

"Come on, Kite! Would you please stop it! What if other passengers will hear?" As Kazuya looks around.

Aki is concerned of what Kite has said. "She may have a point. We may get our memories back, but don't forget about our nightmares. The building that was on fire, what if someone wants us dead?"

Yuki is also concerned. "We got to be ready for anything." Then he looks at Tomo, who is still sleeping. "Tomo. (I'll do whatever it takes to get our memories back and I'll always protect you my little brother.)"
