About How Not to Summon a Demon Lord

Demon Lord follows Diablo, stuck as his game character with Rem and Shera under slave collars. Season 1 has 12 episodes from Ajia-do, directed by Yuuta Murano. Season 2 named Omega has 10 episodes from Tezuka Productions with Okuruto Noboru on two hours, directed by Satoshi Kuwabara. A short mini anime runs alongside as an optional extra.

Season 3 named Ult was announced April 6, 2026 at Tezuka Productions with returning staff and cast, but no date or count has been set. Both aired seasons are marked finished. The light novels continue past the anime, so Ult would follow Omega directly.

Good to know

Watch season 1, then Omega, then Ult when dated. Omega continues the church and demon plots with new heroines, so it needs season 1 first. The mini shorts sit outside the main list entirely. Keep release order and add Ult at the end once it has a firm date locked. Note Omega has 10 episodes, not 12.
