Tasuku Kurosaki 黒崎祐

Kurosaki works as the school janitor. He is also a computer hacker.

He is a drinker, smokes a lot, is violent, dangerous, scary and calls Teru his servant. He is quite good-looking as well. He does not display his emotions normally but when he gets angry, he can be very terrifying. He swears at times, and likes to eat. He is an excellent cook, but usually commands Teru to cook. However, he can be protective of Teru when she is in danger. And yes, he is in love with her.

Meanwhile, the police officers met up with Souichirou, who already had a stomach cancer at that time, to help decipher the codes Jack O' Frost had made, even though the code was extremely difficult, to find the evidence regarding Midorikawa's death. Although Souichirou should not overexert himself, he still did it anyway, because at that time Tasuku was accused of killing Midorikawa, and the evidence inside the computer was the only thing to prove his innocence. Souichirou didn't want to give up on Tasuku, he still believed in Tasuku and he continued to pursue him. Souichirou managed to arrive on time and prevented Tasuku from committing suicide. Everything might seem like it has gotten back to normal, but soon after that, Souichirou died because of his cancer. Upon his death, he entrusted his younger sister, Teru, to Tasuku's care.!~
