Oh! Toumei Ningen 21

Tooru enters the new century, about ten years after first learning to become invisible. During his second year of high school, his ability ceased functioning, and he moved on with his life. Later, while helping his aunt clean the freezer, he finds a forgotten container of salmon roe. Surprisingly, this roe still triggers his invisibility. As before, Tooru struggles to resist using his power once more.
