I have nothing against plums, but when it comes to Ben-To there’s one rotten Ume that’s dangerously close to spoiling the whole tree.
The good part is that, so far at least, Ume hasn’t been a prominent part of the series. After the truly unfunny scene where she stripped Satou in the classroom she pretty much disappeared, and the episode took a huge upswing. The twist this time is a new group, The Hounds. The school kendo team has devised a pretty clever method of getting themselves bento, throwing up a wall of bodies and clearing the path for designated poachers (in this case Satou and Oshiroi). All this was in support of an effort to get those two out of the Ice Witch’s clutches and into The Hounds, but I never thought Satou would go for it – clearly, he’s in this now for the thrill of hunt. For a wolf, there’s no satisfaction in being fed dog food out of a can.
Katou Emiri, filling out a truly impressive cast). She’s an old pal of Satou’s apparently, who shares his love of gaming and perhaps a lot more. Given that she woke up in his bed (and that she’s the second character introduced in the OP), we clearly have some significant backstory to work through there.
