Rusuhara Daiki

The main character... i.e. you. He is a ronin and NEET who has already failed the university entrance exam twice. He used to be a good boy who excelled in both the literary and military arts, but has become a lazy man due to repeated setbacks.

He feels guilty and indebted to his mother, who is kind to him, while his younger sister, Mao, who makes fun of him at every opportunity, hates her 100 times more than he finds her absolutely adorable.

He has an inferiority complex toward Mao, but because he is a sincere person with common sense at heart, he tries his best to suppress his desires. He is not well groomed at all, and his long hair hides his eyes with its long bangs.

Although he is a large man with a muscular body, he is the type of man that women fear before they think of him as dependable. He used to work out and used to be even more muscular, but now he has a sagging belly and the physique of a Showa-era pro wrestler.

Although he is unaware of it because he is a virgin, he has a big dick, and is also very energetic and has a high sex drive.
