Présentation

Mankichi Akira, who works for a major IT company, is doing well at work and in his relationships, but there is one thing about him that's a little different. The rest of his family (mother, one older, and two younger sisters) are "totally unemployed." Furthermore, his childhood friend Minayo just moved in… His goal in life is to help them become independent! And to hook up with his childhood friend! (Source: Comic Trail, translated)
