Season 3 Episode 5 Nefarious Friends for This Sheltered Princess
Megumin senses that the necklace Iris is wearing contains magical power, and she reveals it a magical relic entrusted to her, but nobody knows what it does. Kazuma recognizes the inscription on the writing as Japanese and accidentally activates it, switching bodies with Iris. He then realizes the necklace is one of the Divine Treasures he is looking for. While Iris takes the opportunity to leave the castle unnoticed with Megumin, Kazuma stays behind to pose as Iris until the spell wears off. Kazuma takes advantage of his position to get in the bath with Darkness and Claire, while Iris gets into a fight with thugs.
