Differences from Light Novel

 * The Time omits Hajime throwing more grenades at the Hydra after causing the ceiling to cave-in on it.
 * In the Light Novel, Eri and Suzu do not interrupt Kouki while he is talking to Kaori and Shizuku about Hajime.
 * The Anime omits Kaori and Suzu's conversation with Eri over her perceived uneasy feelings with regards to her Job as a Necromancer.
