Sisters

Do-S lands repeated hits on a battered Fubuki and, believing the hero's mind is hers to command, closes in to explain her scheme: use Fubuki as bait to draw out Tatsumaki. The plan backfires. Fubuki, furious, hurls Do-S back and follows with her Hell Storm technique, wounding the monster slightly, and it becomes clear she was never actually under mind control. Do-S adjusts, resolving to kill Fubuki outright rather than use her as a lure, but Fubuki tells her that Tatsumaki would have come regardless.

A tremendous explosion rips through the area as Tatsumaki arrives. Grasping her error, Do-S looks for an escape just as a fleeing monster drops before her, begging for help and warning about Tatsumaki. Tatsumaki appears and orders Fubuki to go home and leave the rest to her. Do-S sends her love slaves to swarm Tatsumaki as cover for her getaway, but Tatsumaki freezes them effortlessly and warns Fubuki that such people are a burden rather than allies. She then departs to track down the remaining monsters.

Fubuki reveals she resisted Do-S's mind control all along and retaliates with Hell Storm. Do-S shifts from using Fubuki as bait to trying to kill her. Tatsumaki arrives with a massive explosion, immobilizes Do-S's love slaves, sends Fubuki home, and moves on to hunt the rest of the monsters.

Fubuki and Do-S share the online cover. Using the unconscious bodies, Tatsumaki spells out Ashidematoi, a Japanese term for someone who holds you back. The online cover page also features Shigeo Kageyama, Dimple, and Tome Kurata from ONE's other series Mob Psycho 100. The chapter belongs to Volume 12 within the Monster Raid Arc and was adapted within Episode 18.
