Volume 12 challenges Yakumo's usual methodology. Typically, Yakumo solves cases by communicating with the spirit to resolve their lingering regret. In Inishie no Kioku , the conflict may arise from a phenomenon that cannot be simply "talked down." This tests Yakumo's spiritual abilities and forces him to rely more on deductive reasoning and his uncle Isshin’s guidance regarding spiritual lore.
Without spoiling the core mystery, Volume 12 reintroduces the series' most terrifying antagonist: the serial killer with a distorted sense of justice, often referred to as "The Imitator." The volume also tests the relationship between Yakumo and Haruka Ozawa, pushing their emotional bond to a breaking point due to the psychological toll of Yakumo’s abilities.
Yakumo does not romanticize his power. He views spirits as beings tethered to the mortal realm by unresolved "causes" such as grief, anger, or a desire for vengeance. This pragmatic philosophy is challenged when he meets Haruka Ozawa, a classmate who seeks his help to exorcise a spirit haunting a friend. This partnership forms the emotional core of the series, blending supernatural horror with procedural detective work.
