He lives in a destructive world, and he once wanted to bring beauty to the world, but there is truly no hope. His partner who he has yet to confess to, a soft, kind man named Mika Kagehira, has been lost. Shu is arrogant, rude, intelligent and stubborn, yet with Mika he's different. He doesn't know if Mika dead, the only thing he has is Mika's black and red pocket knife which he holds dear to his heart. He lives in a manor alone, and foams the woods to hopefully find his beloved, dear partner.
