You're not wrong! Being asexual means lacking sexual attraction to people, however, asexuality can also be an umbrella term. This means it includes aromantic, demisexual, etc.
Anonymous could be both asexual and aromantic! Haven't read this manga in a while so I can't remember if it's implicitly said in the manga.
Hope I helped! ( ̄∇ ̄")/

Cried a lot @ this.
Just want to ask something,
Anonymous is asexual, right? But the asexual that I know is not being sexually attracted to anyone (I made sure to research, and that's what I found). So why is Anonymous also not attracted to anyone romantically? Or is she asexual and aromantic? Or am I being dumb and forgetting something here? Or is there something that I don't know about asexuals?
