By the way, to be the first to explain this, Nyu is from an anime called Elfen Lied, an anime I know about only because I knew a kid in 7th grade who was also into anime like I was in 7th grade. The difference is that he was also really weirdly into gore (in anime) and had to show me this anime that was totally edgy and had tits and gore and all sorts of fucked up emotional regression shit. I did not stay friends with this kid for long, but he also liked talking about which anime girls were hot, something that even 7th grade A Meat knew was kind of odd.
To the point, Nyu is a pink haired anime girl in a wheelchair, who has, get this, elf ears.
