Liz is a succubus who appears in one of Marin's favorite slice of life series, "SuccIDK." Marin had some interest in cosplaying Liz-kyun but didn't think she could pull it off until Wakana gave her a little push. With the cosplay ready, they head to a studio for a photoshoot, but the studio happened to be a rather unexpected location.
