Sometimes the truest families are bound by friendship and experiences, not by blood. This is what the Igarashi Tribe, led by Hiro, is founded upon. For almost two decades their bonds were forged through the hardships they face, and cannot be broken by any means. The universe has it in mind to expand them as a family, however, and one by one, they're in for the experiences of their lives.    

Yuri's life has always been bland, the same old routine everyday doing nothing but work at the pub – that was it. Until she met Amamiya Hiroto, a regular at the pub with a very messy past.
