Blitzkinder Academia: Vincent Von Drathen, "... but I'm not a monster..."

Vincent doesn't find that having one extra chromosome is at all amusing. Such mutations tend to have side effects. To wit, most boys never have to go shopping for a comfortable bra.

If having an extra X chromosome was his only dilemma, then he wouldn't be enrolled in a superhuman academy.

Vincent has access to a (usually) cooperative monster that makes a squid look like a guppy in comparison. And that's in the "utterly not cute" sense. Fortunately, it's usually invisible. Unfortunately, it might as well be a cojoined twin.

Most of the other students don't mind, though. After all, they have their own issues.
