Toaru Kagaku no Akuserareta - Season 1

Accelerator is considered the most powerful psychic in Academy City and one of a few able to shift to the level 6. He, however, now lives a peaceful life and tries to recover from the past injuries. His rest is interrupted, when a rogue group within Anti-Skill called DA that is obsessed with bringing justice to Academy City so much that it would even opt for kidnapping and experiments on humans, causes pure havoc in the city. While Accelerator does not like to be bothered and hates problems, Disciplinary Action, or DA is enough of a threat for Accelerator to take actions, mainly because of the fact that the group, for some unknown reason, is trying to kidnap The Last Order. Now only Accelerator can save the Academy City and The Last Order from the zealous fanatics, working in DA.
