Last time, on Precarious Woman Executive Miss Black General!
Thank you, General. Volume 10 picks up with Old Fart Numbers 2 and 3 - Usa and Turtle - and Flat-Chested Lady in an Outfit Too Young for Her - Oobaa - still fighting Hulking Shark Man. Carcha decided heroes today are too weak to preserve the peace the 4 of them fought for, so he's going to tear it all down. As the General, of all characters, will later point out, it doesn't make a hell of a lot of sense to fight hard for peace, then get angry because people aren't being as serious as you'd like in the more peaceful world you created.
Carcha is taken down via some teamwork from X-Chan (the tentacle monster RX's Scientist created) and Licht, the son of the world' premier hero. The two haven't seen each other since the exhausting 5th volume, when there were so many tentacle sex jokes I nearly abandoned the series, but Licht is clearly still infatuated and eager to work with the tentacle girl of his dreams. Anyway, they incapacitate Carcha long enough for Braveman to land one big hit and calm things down. But hey, Mother Justice has got to be pretty impressed with her son, helping to end all this chaos, right?
The battle and resulting fallout on both sides, takes up the first third of the volume. The "Organization" - all 3 of them - are captured, and Carcha is allowing himself to be kept in custody. The Hero League has, you know, I still don't care about internal struggles between faceless (literally, they're just drawn as shadowy outlines) bureaucrats, move on.
The Villain League, despite being instrumental in the victory, are mostly not pleased with how they did. This leads to infighting, and a competition to see which of the non-RX groups can get the most views on a video they posted about their group. The Monster's Benefits Society starts strong, but doesn't nail the landing. The Mecha Mountain Gang inadvertently post a terrifying video. The Rogue Roses, um, violated terms of service with their video, and BDS's video was a complete flop. It's a silly chapter, but it helps highlight the differences between the groups.
Then Jin busts out consecutive chapters at the pool, because he wasn't getting enough fan service in there already with the Rogue Roses' video. The first (Swimsuit Episodes are Always Good, No Matter How Many Times You Do Them) about RX hijacking the city pool for a vacation day and the damn pervy cat trying for a photo of one of his female coworkers after a clothing malfunction. The second (Enough with the Swimsuit Episodes Already) turns into a souped-up water gun war as several of the heroes, planning their own fun day at the pool, discover RX's treachery. It does have a cute ending as Frosty is very happy to be get to have a fun day at the pool. Turns out people typically don't invite the person with ice powers along.
After that, Jin adds another new character, as RX tries to seize on their newfound notoriety thanks to the whole mess with the General-robot, by going on a recruitment drive. This brings the General back into conflict with a creepy lady she met in an early volume. Well, creepy lady got herself a partner, a big lady named, appropriately enough, Eight Foot Tall-Chan.
While incredibly strong, Eight Foot Tall-Chan really just wants to make friends, and the General, for all her many, many, many, many, many faults, can be a friendly and considerate person. So she offers a position in RX. Is this shy, innocent young woman really cut out for a life of villainy or, whatever it is RX gets up to most of the time? Well, it's all in how you frame it, and RX, the pervert cat aside, are a tight-knit group. Boss can't really bring himself to scold the General for running off, and Secretary-San tells the General she wants to come along next time the General goes rogue.
Workplace solidarity is lovely.
