Shin Tokiwa Age: 28 Height: 182cm Office Manager / Accountant Shin grew up in an orphanage. At age 10, unable to endure the violence and verbal abuse from the staff, he ran away. In the city he fled to, he was cornered by some scary-looking men, only to be saved and taken in by Tesshin, who was the young head at the time. Since then, he has lived with the Yamashiro Clan. He rarely engages in combat, instead handling the clan's accounting and office management. Personality: Calm and composed, his expression rarely changes. He doesn't shout, but when he gets angry, his voice drops and he gives off a bloodthirsty aura.
