Okami-san Goes on a Double Date with Jizou-san - S1.E7

A girl named Ami Jizō has been secretly preparing food for baseball player Jin Hanasaki, as she has a crush on him, but is too shy to talk to him. Although he doesn't have feelings for her, he offers a date to repay her, with Ringo making it a double date with Ryōko and Ryōshi to ease her nerves. They go to the cinema, the arcade, the pet store and the park. Halfway through the date, Ryōko spots a cat stuck up in a tree and, upon going to rescue it, falls into the pond and hits her head. She ends up contracting amnesia, believing she's 13 years old, and has a completely different personality to her usual self. While Ryōshi looks after her in this state, Ami and Jin are left alone on their date. When Ryōshi and Ringo try to figure out how best to deal with it, Ryōko feels she is being ignored and runs off into the rain where she runs into Shirō. As Ryōshi catches up with her, he learns that Shirō assaulted her when she was younger and no one believed her, and he swears to hunt him down.
