(W) Yumi Tamura. When Totonou goes to Hiroshima* his only goal is to finally see an art exhibit (and maybe run into his fugitive best friend). But instead* Totonou gets dragged into a battle of wits. Kariatsumari Shioji is a teenage girl who needs his help. Shioji and her cousins have been named as beneficiaries in their grandfather's will* but they'll only receive their share if they can solve a cryptic puzzle. If that wasn't enough* Shioji suspects that her cousins are willing to kill in order to win. After all* last time there was an inheritance battle in the family* a whole generation ended up getting wiped out. Can Totonou unravel the mystery before there's another bloodbath?
