Nanako hates the rain because it makes her hair frizzy, but Amane tells her it’s not that bad—if she walks home with someone while sharing an umbrella, they’ll be “together forever,” and that’s something with which Nanako can get on board.
As a result of the last storm, a tree destroys the school rabbit hutch, so it’s up to Eiji to fix it, but while picking up branches his hand get riddled with splinters, necessitating a trip to the nurse…who is just Koto in nurse cosplay. Even not in the running, she’s going to have her occasional fun with him.
When Kino joins the reconstruction effort, she envisions a grand, avant-garde, Gaudi-like creation that’s simply too much for a rabbit hutch. Yet, when the hutch is rebuilt, the door falls off the hinges and all the rabbits escape, making Tao’s prophecy come true.
Thankfully, Amane sends a message through the PA for anyone who finds a rabbit to capture it and return it to the hutch, and all the rabbits are retrieved. All that’s left is for Eiji and Nanako to walk home, but since both of them forgot umbrellas, Amane provides a key assist by giving them one of hers. All’s well that ends well!
