Yuubaru is a typical eccentric artist: he even claims that if you're not ridiculous, than you're not an artist. Despite this, he is very dedicated to what he does, and will not draw anything that he doesn't want to.
Yuubaru has short turquoise hair (black in the anime) and brown eyes. He wears the standard men's uniform of Hakoniwa Academy, with an apron on top of it when he is painting. At the Seiyasai, Yuubaru wears a dark colored scarf with his uniform. Ten years later, Yuubaru wears a beret and a smock.
Student Council Executive Arc
Yuubaru requests that Medaka Kurokami model for him, wanting to use her in a contest of which the theme is "Beach Goddess". Though he believes he to be perfect at first, he finally decides that she is too perfect, and that she has no merits towards the fine arts. Zenkichi Hitoyoshi and Kouki Akune leave to find new models, bringing him Isagi Isahaya and Nekomi Nabeshima respectively. He rejects them as well, deciding that the two of them are too scary. After Zenkichi and Akune offer themselves up as models, he initially becomes excited, before realizing that a painting of men won't work with the theme. When the girls insist that he is being too picky, he refutes them, saying he will only paint the perfect beach goddess. When Hansode Shiranui arrives at the Art Club room looking for Zenkichi, he decides that her underdeveloped body is the model he has been looking for (upsetting the other girls quite a bit), as she represents the most "potential". Later, he paints a group portrait of the six of them as thanks.
At the club battle swim meet, Yuubaru is seen as one of the participants representing the Art Club, despite his earlier claims not to be a member. He appears to be chatting with Nekomi Nabeshima. During the final event, the cavalry battle, Yuubaru is seen as one of Nabeshima's victims when Tanzaku Aso explains how the Judo Club won the competition.
