Details

A pediatrician at a large hospital in Tokyo. Formerly an obstetrician.

He is calm, soft-spoken, and provides a sense of security. He is highly trusted by medical staff, patients, and their families. Popular with children. He has characteristic smile lines. However, since his wife's death, he can no longer smile genuinely enough for them to appear. He suffers from self-loathing over his inability to save his wife and his failings as a parent. 　

Past

After Guest was born and his wife died, he struggled with childcare and developed a nervous breakdown. He nearly snapped at a crying Guest once, and the shock of his own potential for violence led him to distance himself, hiring a babysitter and focusing on work. This also reduced his time with his other sons. 　

Currently, he leaves household chores to a housekeeper and buries himself in work.

　

Love and Hate for Guest

The child of his beloved wife, yet the one who took her life. He is torn between the duty to love his wife's last memento and the resentment of her "murderer."
