You don’t have to be a psychic to figure that educating people living under a bridge with common sense wouldn’t go well. Surprisingly though, it wasn’t that bad until Stella showed up and demanded 100 trillion yen for running a school on her turf. Despite how much Riku tried to ignore her initially, she was clearly going to have none of that as she barged in on their bottle rocket science experiment. While Riku was busy fearing for his life, a lot of the humor came from Stella’s gangster talk as she demanded payment and told him to make sure his school produces the evilest armed crops like at her orphanage. Given her shady upbringing by Sister, it was pretty clear that Stella was serious about all that, but it was still all a ruse to hide the fact that she was lonely without the Testujin brothers.
Despite her dishonest self eventually coming around and joining in on Riku’s class, it still didn’t change how creepy Stella was for writing bottle rocket good luck charms such as “world domination”, “self-greatness”, and “unrivaled”. Even the things she taught Tetsuo and Tetsuro would make anyone think as much, with her opting to tell them that “kejime” means to “take responsibility” (the colloquial yakuza usage) rather than “make a clear distinction”. There were some positive outcomes from Riku’s new job though, which include chasing off Sonchou after he asked for Riku’s shirikodama (i.e. a mythical ball contained in the anus) and getting back at Hoshi by having Nino say she’d rather attend Riku’s classes than his concerts. In the latter case, it actually made for a sweet couple-like moment between Riku and Nino too, before teaching the Testujin brother’s of magnetism made them believe that Riku also has super-human powers that need to be suppressed.
Anyway, the gags are plentiful as always, but I find that they’re pretty hit and miss on me at the same time. P-ko’s infatuation with Sonchou’s green pepper-like color and long-flowing wild hair that he can adjust the length of on a whim would be an example of a disturbing miss, since it’s so wrong for so many reasons. After seeing that, I’m actually grateful we’ll get to see some normal people for a change, since Ichinomiya Kou’s people have finally come looking for him. However, judging from the dialogue he had with P-ko at the end, it seems like Riku/Kou has lost his own grasp on what common sense is from the time he’s spent under the bridge. *Insert dramatic music*
