Dandadan Chapter 170

Koki Yukishiro moves like a ghost through school—unseen in hallways, unheard in class, and increasingly unmoored at home, where praise pools around her prodigy sister, Alice. The chapter cuts to the root of her desperation: a need to be seen that curdles into self‑harm online and, finally, a bargain. An “orchestrator” confronts her with the truth and a blade: keep your secret, but steal power for me.

Meanwhile, the History and Culture Research Club goes methodical. Momo spots the girl from the library incident; Koki bolts. Sanjome scolds the runners, then drifts back into his own private puzzle. The team boxes Koki into a classroom with a simple plan—Aira and Okarun front, Jiji and Bamora cover the rear—only to find an empty room where she should be.

A Suspicious Woman pivots dandadan into the Kozuka Knives arc’s core themes—visibility, coercion, and consent. It’s a chase on paper, but under the floorboards something else is moving: a system that turns vulnerable students into pawns with a single whispered “yield.”
