A Corpse is Buried Under Sakurako's Feet: The Butterfly Vanished in November

桜子さんの足下には死体が埋まっている 蝶は十一月に消えた

Sakurako Kujou, high schooler Shoutarou Tatewaki and their homeroom teacher Isozaki are out collecting bones in the forests near Asahikawa when word reaches Isozaki that one of his students has gone missing. What the woods give up ties the disappearance to Futaba Nishizawa, a girl who vanished two autumns earlier, and the trail leads the three to an abandoned house and the painter living inside it. This manga adapts The Butterfly Vanished in November, the fourth Sakurako-san novel.
