S1·E6 Let the Shipping Wars Begin!

A new anime, Katchu Ranbu, or Kachu Rabu for short, has started, and it's hugely popular. Bot Kae and Nishina are elated about the show, until they find out that they each ship Lord x Akane and Akane x Lord respectively and get into a huge fight. Their friendship appears to be heading to a halt, so Igarashi, Nanashima, Shinomiya and Mutsumi try to help the pair out. Unfortunately, it looks like their reverse ship war is just heating up.
