Ikeda-san

The master of Ikeda manor and former president of the Imperial University's School of Medicine. He adopts Kawase after being drawn to his ambition to become a doctor. He also shares a close relationship with Katou-kun whom he regularly visits at Sanzendou.

It is revealed in the last route that he is still very much alive and does not possess any of the nefarious traits Tamamori gave him in his stories. The only reason Tamamori made him into such a spiteful character is due to his grudge against him./
