In a substory in Yakuza and its remake, a young boy is struck down by appendicitis. Kiryu first meets Emoto in this situation, after asking locals for the nearest doctor. A pair of foreigners are outraged that he has prioritized the boy's care above that of their unconscious brother, and go into the operating theatre to try and confront him. Kiryu however, knowing the criticality of the boy's situation, fights them off in order to prevent them from interfering with the operation.
Afterwards, the foreigners tell Emoto that he let their brother die, only for Emoto to hit the unconscious man in the stomach, waking him up. He explains that whilst the boy was only moments away from a possibly fatal burst appendix, the foreigners' brother was merely passing a kidney stone.
Yakuza 2/Yakuza Kiwami 2Edit
During the events of Yakuza 2 and its remake, he helps Kazuki and Jiro Kawara after they are shot and later Goro Majima. In a moment mirroring the previous game's substory, whilst Emoto is operating on Kazuki, two foreign men burst into the operating theatre, and Kiryu has to drag them back out again and fight them off.
