His motto as a doctor is: "There are lives that cannot be saved just by waiting." While TOKYO MER's mission is zero deaths, he lost his younger sister, Suzuka Kitami, at a scene. Despite his treatment, she unfortunately passed away. He was depressed for a while afterward, but he continues to be a doctor at TOKYO MER to honor Suzuka, who told him, "I love my big brother when he's saving people." His hobby is muscle training; he claims that even doctors need muscles. Thanks to that, he can be seen charging into rubble or running while carrying the injured.

Currently, MER has been officially authorized, and he is the Director-General who commands MER units nationwide under the MHLW's direct control. Since TOKYO MER is under the Governor's direct control, it is technically outside his jurisdiction, but he sometimes takes command when they collaborate with MHLW-controlled MER units at a scene. Occasionally, he goes into the field to work as a doctor. At those times, the TOKYO MER members call him "Otowa-sensei," while normally he is called "Director-General Otowa." He is a long-suffering man constantly swung around by Kitami's recklessness, but he empathizes with Kitami's motto as a doctor and likely approves of him deep down. However, as Director-General, he almost never gives verbal permission for Kitami's reckless actions. First person: I (polite/formal)
