Yeah, the powers in this setting are pretty weird.
My two favorites have to be Special Thursday, which lets you telepathically command a UFO, and Sudden Death Sauce, which lets you control the spiciness of any curry within your line of sight, with the spiciest curry making the eater's head literally explode.>>59251195
Real talk, all the cutest waifus are genderbent dudes. Jyakenou is a genuinely sweet and thoughtful person, and their female form is beyond adorable, they're the one with the pink hair in the middle of this picture. But they're male form is the biggest ball of testosterone you've ever seen, and that is their default gender.
Otome is pretty cute too, but still, genderbent, as a boy for most of the story.
As for natural females, the student council has some good ones, though I don't know all their names from memory.
There's one who's bland but pretty sweet all around. However, her power is a virus that only targets men when active. It makes their balls explode before their entire body is afflicted with every disease known to her.
There's Deathako. Who is the yandere to end all yanderes, but she's still pretty cute and innocent in her own way. All she really wants is someone who won't shun her. Her power makes her crushed go insane until they kill themselves if she thinks they betrayed her.
There's one who's pretty peppy, and her power isn't even horrifying. It just lets her detect mental stability, and force them to be mentally sound.
There is one other girl though, I might actually have to get into her in a separate post, she is... definitely a piece of work.
