Summary: What happened to Amakusa Ryuu before he entered DDS? Ryuu have twin? Where is his twin now? What make Ryuu want to go to DDS? Why Ryuu grew fond to Kyuu? Why Ryuu and Kyuu have some kind of special bond between them?

"Ahh….the hard case finally we solved yesterday. I can't believe we took so much time to solve it," said Kyuu while went to his place and sat on his chair. Ryuu who sit beside Kyuu just smile. "yea.. Making us all so tired…" whined Megumi, the girl with photographic memory ability. "I can't use my internet there, that's why we were in trouble for awhile," said Kazuma, the genius programmer. Kinta knocked Kazuma's head and said, "you depends too much on your computer." Kazuma rubbed his head. "Its hurt stupid," said Kazuma. Ryuu, Kyuu and Megumi just laugh looking at those two.

"Good morning everyone," suddenly they heard Dan-sensei's voice. They immediately went back to their places. "Good morning Dan-sensei," replied them in unison. "All of you solved the case yesterday really well," praised Dan-sensei. All of the Q class smile widely. "I want all of you to keep your great work and improve it for the future cases," said Dan-sensei. "Yes, understood," answer all of the Q class in unison.

"Now I want to introduce all of you to the new student, please come in," said Dan-sensei. A boy came in the room. "R…Ryuu…." Everyone in the class look shocked. "Shinzo…" whispered Ryuu. That boy has the same face and figure as Ryuu but he has silver hair. He wore a black long sleeve shirt and long black jeans. "Hello, I'm Shimizu Shinzo," Shinzo wrote his name on the black board. "The heart of the death water…" Megumi muttered the meaning of Shinzo's name. "Hello Ryuu? Long times no see," said Shinzo. "You know him?" ask Kyuu. "He's my twin. Hello Shinzo," replied Ryuu. Everyone kept their selves silent.

"Okay okay. Let's start our class now. Open the text book page 137," said Dan-sensei. That day, class went smoothly as usual. After the school ended, all the Q class start gathered around Shinzo. "How come your surname is different from Ryuu?" asked Kinta. "Our parents divorced. I followed my mother and he followed my father," replied Shinzo. "Where were you from?" asked Megumi. "Australia," replied Shinzo short.

After they asked few questions, Kazuma said, "I have to go now, see you guys tomorrow." "I also have to go. I have to go to my part-time job. See ya," said Kinta. "Ah, wait! I'll go with you two. Bye you three" said Megumi. "Ok, see you all tomorrow," said Kyuu while waved at Kinta, Kazuma and Megumi.

"So, we also should get going," said Shinzo. "You want to come to our house? I mean, Ryuu lived with me, so my house can be considered as his house too. So you want to come? My mom will get excited to see you," suggested Kyuu. Shinzo looked at Ryuu who avoided his gazed.
