Kage no Jitsuryokusha ni Naritakute! - Episode 2 - Claire Knocks Cid Back

Cid's older sister Claire is an incredibly skilled swordfighter. Cid hides his skills.

Cid cured a blob of demonic possession, and it turned into a beautiful blond elf. Cid named her "Alpha," the first of his Shadow Garden group.

A villain had kidnapped Claire, so Cid and Shadow Garden quickly moved to rescue her. Claire didn't need any help to escape, but Cid and his girls killed everyone in the villain's lair.

Alpha took the first turn of the Shadow Garden girls in the end card.
