The first time Minoru spars with Mutou; after being unable to hit the gorilla, he decides that a jumping kick will work. Mutou's response? He easily avoids it, grabs Minoru's leg, and throws him onto his back, while stating that something like that won't hit him. All with a rather bored expression.
At the club's party following the Kaburagi Ryu preliminaries, Minami finds out that none of the girls he invited are able, or willing, to attend. After seeing Kohinata and Mutou with their respective girls, he loses it, proceeding to chug down a bottle of booze and start doing a nude Happa Dance, decking Minoru when he tries to calm him down, before being joined by Pedro and Saizou. The girls all freak out except for Haruka, who's seen casually sipping her drink at the end of the chapter.

Chapter 178: Minoru takes Nana out for Christmas Eve, but it becomes a textbook example of a Bad Date. They go to a Thai restaurant, rather than a more upscale place. Then it turns out that Minoru didn't even know that it was Christmas. Then it turns out that he's more interested in the Muay Thai matches that take place in the restaurant. Then it turns out that he only bought Nana along to take advantage of the couples discount the restaurant offers. By this point, one of the restaurant's employees has to physically stop a furious Nana from bludgeoning Minoru with a wine bottle.
