>>33627248Goth imouto neighbor's name is Narumi, her character is Nyarupi.
Protag cares for Narumi but wishes she'd treat him with more respect like she used to when she was a kid. But also he's so gachikoi for Nyarupi that when she uses her Nyarupi voice he hallucinates that she's Nyarupi and will do whatever she says.
Narumi trash talks the protagonist and calls him a dumb simp. And sometimes Nyarupi lets out evil smirks as she manipulates him. But it turns out that Narumi secretly hates how bitter and jaded she's become, and needs the mask of Nyarupi to admit her true feelings. In fact, she only became a VTuber because she saw the protag experience unicorn heartbreak with a flesh idol - she literally handed a pic of that idol to her mama and said "I want a design with this kind of feel".
