STORY

Housewife Sanae Hatakeyama and her family of six live in the antique shop "Mori-no-ya." Her husband Minoru was the first Japanese prisoner when war broke out with the U.S., and close to 30 years had passed without his return. The seemingly ordinary Hatakeyama family had survived a great disaster that occurred at a nearby chemical plant, and had also been witnessed several times over the years with the exact same family members. Therefore, there were suspicions that they were immortal superhumans. After the Superhuman Bureau gets curious about the family, Fuurouta and the others start on a secret investigation. But then, Sanae receives word that Minoru is returning.
