It’s been a few years since we got the home video release for Inou-Battle, aka When Supernatural Battles Became Commonplace, but Sentai brought out a new bilingual edition 2020.
The series features the opening sequence “OVERLAPPERS” by Qverktett:II, as well as the ending sequence “You Gotta Love Me!” by Kato*Fuku.
With thirteen volumes of light novels to its name before ending in 2018, Studio Trigger handled the anime production for the series.
