Ootsuka is a supporting character in the anime After the Rain, an adaptation of the manga of the same name. He is a male employee who works in the kitchen at the family restaurant Garden, the workplace where much of the story is set. He has a tough-looking appearance and a sturdy build, with black hair and black eyes, and he is Japanese.

His role in the story is that of a minor figure within the restaurant staff. As a kitchen worker, he handles food preparation behind the scenes, so he remains at a distance from the front-of-house interactions that the story mainly follows. He does not receive a personal storyline of his own, and his influence on the plot is limited. Instead, he contributes to the everyday atmosphere of the Garden restaurant, helping to create the sense of an ordinary working environment in which the main characters spend their time.

Given his limited presence, the story provides little detail about his personality, motivations, or private relationships beyond his position as a coworker. His most notable trait is his physical appearance, which is rough and sturdy and makes him stand out among the other employees. His work in the kitchen also points to practical cooking skills, though the series does not explore them in depth. He appears as part of the supporting cast in both the original manga and the anime adaptation.
