Itsuha Mitsukura

An unassuming girl who doesn't stand out in her class. However, as her classmate Kyosuke finds out by chance, she has an extraordinary obsession with bodybuilding, and is seriously aiming to have eromanga-like proportions. She gets validation from posting incognito selfies on Instagram, but despite being so fit and hourglassy, her self-image is still very distorted and far from her own ideal. When she finds out that Kyosuke has been drawing her in lewd poses, she becomes interested in him and starts asking him to draw her more and take pictures of her, and the two develop a secret and unlikely friendship.
