Actually, I believe in the real world, she didn’t even go back to Tevua. That, I believe was her biggest regret that caused her to think she was useless. She felt like a useless gear because she did nothing to help the situation of her mother. At least, that’s what I think about it and why I think the ending resolved it.
Now, in reply to @EisenKoubu, well… I really don’t know what to say. I really enjoyed Kud’s route but I am well aware of the flaws, and I’m not even surprised people hate it. But it gave me feels and that’s what I’m after so… I can’t complain about it
Yes, the flirting and studying and discussing about her issues with feeling alienated were, in a way, pointless. They weren’t resolved in the end and, really, the only part that actually had a significance on her route was everything after they announced the struggle in Tevua. Everything before that was, while somewhat entertaining, still not significant to the ending.
Plus the romance wasn’t even nice xP Haruka’s route had pretty nice romance even though it wasn’t so significant to the route. Then again, most of the other routes in LitBus had pretty bad romance and I never thought highly of them.
Also, I believe the NSFW CGs he are talking about are the body painting. I honestly don’t see them as much of an issue, really.
