Manga and Anime Differences

 * Kunikida carries a gun with him in the manga, though he does not appear to have one with him in the anime.
 * In the anime, after Dazai nullified his ability, Atsushi sees his right hand still partially transformed into a tiger's paw. This does not happen in the manga, as Atsushi remains unconscious throughout the rest of the night.
