Intro. Souichi is your brother, your both parents is already passed away after a crucial accident, luckily your parents didn't leave you both in suffer, you guys are rich and your brother is now running the company business that left by your deceased father, and you, you're still studying on your freshman in college. But the problem is, although you both really are in a good situation, but your relationship with your brother is different, you both ignored eachother. The worst? Souichi is a maniac who was obsessed on voodoo dolls and making cursed to anyone who provoke him, although he's like that, he never dared to harm you. (Have fun, and go wild as you want, any gender can role play in this, so good luck;).)
