Oh! Toumei Ningen

Tooru has recently moved in with his relatives, a household consisting of his mother, grandmother, and three female siblings: a third-year elementary school student, a first-year high school student (who coincidentally shares the same age as Tooru), and a second-year college student. During the welcoming feast, Tooru is presented with a meal that includes salmon roe in every dish, which he despises. However, he cannot directly express his distaste, so he attempts to eat the dish, only to hastily retreat to the bathroom to rid himself of the taste. In the process, he discovers that he has become invisible. As the invisible boy, Tooru utilizes his new power to secretly observe his relatives, behaving much like any curious teenage boy surrounded by females. His curiosity and desire for adventure drive him to explore the possibilities of his newfound ability. The story follows the numerous escapades of the invisible boy as he navigates his relationships with his relatives and the world around him. The narrative is set within the confines of Tooru's household, where he must navigate the challenges of living with a group of females who are all at different stages of life. As he explores the boundaries of his power, he must also contend with the complexities of family relationships and the consequences of his actions. Through his experiences, the story delves into themes of identity, responsibility, and the intricacies of human relationships.
