>So does Umaru have autism?
no but kirie probably does
Nah, the show is just trying to show how the way we present ourselves to the world is different from how we act on our own( or in Umarus case, around her brother/Kirie). It's about how when our internal personalities start to show we can be happier. Shows always over exaggerate personalities to make their points.
the ability to sosun is insignificant next to the power of the shinkansen
>Ebina's self conscious of her accent, that's why she's awkward.
Also she's a high school girl from a rural area living by herself in a big city. She's the only girl in the show with no family support, so she's under a lot more stress.
