Ep. 9: Tatsumi y Kasumi navegan un baño compartido inesperado con Wakasa

9

Kasumi comes over to visit while Tatsumi is changing the bathwater and demands to take a bath together with her brother. Tatsumi initially refuses because he does not like having Wakasa see his sister naked, but Wakasa persuades him to accept. Kasumi and Tatsumi try blindfolding Wakasa to protect Kasumi's privacy, but Wakasa insists on joining in because it sounds like the siblings are having fun and he feels left out. Kasumi and Wakasa make friends over their shared taste in bathing products, and during the credits, Kasumi persuades Wakasa to send photos of Tatsumi to her by promising to pay him with his favorite shampoo.
