A Certain Scientific Accelerator

The day arrives for Accelerator's bandages to come off after he is shot in the head, and Last Order is eager to celebrate. A secret weapon is stolen from an atmospheric research facility, and the culprits seem to be targeting Accelerator with it.

A high-school-age girl attempts suicide, but finds herself at the mercy of a fanatical group calling themselves "DA." When a young woman carrying a photo of Last Order is pursued through the hospital, Accelerator determines to find out why.

Esther leads Accelerator to the warehouse where she was once held, where they encounter a more advanced "coffin" controlled by Hishigata. Accelerator tries to learn more about DA. Esther reveals more about how her necromancy works.

Accelerator takes on the two DA members in the hospital morgue, and receives assistance from an unexpected source. When DA once again messes up a mission at the hospital, plans go into motion to have them removed from the operation.

As Accelerator is sidelined while his Misaka Network electrode recharges, Antiskill leads a raid on a supplement factory being used as a front for DA. Meanwhile, the members of Scavenger carry on their mission to eliminate DA.

Yomikawa attempts to defend Esther, Huotou, and the Sisters clone from Scavenger's attacks, and learns why they are so hostile to the city's teaching staff. Huotou fights back against Naru, with help from Esther, but will it be enough?
