From one of Japan's most notable graphic novelists: a heartbreaking and redemptive tale of mourning and acceptance. Yaichi is a work-at-home suburban dad in contemporary Tokyo, married to wife Natsuki, father to young daughter Kana. Their lives are suddenly upended with the arrival at their doorstep of a hulking, affable Canadian named Mike Flanagan, who declares himself the widower of Yaichi's estranged gay twin, Ryoji. Mike is on a quest to explore Ryoji's past, and the family reluctantly but dutifully takes him in. What follows is an unprecedented journey into the largely still-closeted Japanese gay culture: how it's been affected by the West, and how the next generation has the chance to change the preconceptions of and prejudices against it.

The concluding volume in the story of Yaichi, his daughter Kana, and how their meeting Mike Flanagan - Yaichi's brother-in-law - changes their lives and their perceptions of acceptance of homosexuality in their contemporary Japanese culture. As Mike continues his journey of discovery concerning Ryoji's past, Yaichi gradually comes to understand that being gay is just another way of being human. And that, in many ways, remains a radical concept in Japan even today. In the meantime, the bond between Mike and young Kana grows ever stronger, and yet he is going to have to return to Canada soon, a fact that fills them both with impending heartbreak. But not before more than a few revelations come to light.
