Portrait of Memories.Six years previously, Chihaya Senō arrives at the village where she will be the new teacher at the village. Senō is harassed by Atsushi Kuga, a bully at the school, and the principal gives her a warning for slapping Atsushi. It turns out that Atsushi is a Seki and regarded as near-royalty by the townsfolk and, therefore, his boorish behaviour is overlooked, even though his is barely able to control his kakushi. To get back at Senō he has started false rumours about her, ruining her reputation in the village. She plans to resign from her post, but, after a brief encounter with Aki, she decides to return to school and continue her work; the rumors become worse. When Atsushi attempts to seduce Senō a second time, Aki intervenes and takes her to his house where they later make love. Unfortunately, she is forced to leave the school after evidence of their encounter is made public. Atsushi takes Senō captive and Aki arrives to save her. When Atsushi attacks Aki with Kuramitsuha, Senō jumps in front of him and is killed. This causes Aki to go berserk, wrest control of Kuramitsuha from Atsushi and slaughter him and his friends in vengeance. Aki is eventually overwhelmed by other Seki and is sent to prison.
