Words, doodles and magic

Green Creek Series:

Kelly Bennette: Canon, (yay!) but was worried the author was going to pull something for a moment (no fault of the author, I'm just used to having the rug pulled from under me). But he's very ace, and I love him dearly.

Hirano to Kagiura:

Hirano Taiga: Hirano to Aro/asexuallity, it was Laios Touden is to autism. Canon in any way but name even if unintended by the author. Love him dearly. Also Hanzawa Masato: Not canon, but if you ignore certain dialogue he kinda swings that way. Works really well with repressed aro/ace or comp-het headcanons.

In Stars and Time:

Siffren, Mirabelle, (Loop): Canon (yay!) Also Odile: Because she gives vibes of someone who's not interested in romance. Also rule of cool (If I think a character is slaps or they are my fave, they get an automatic label)

DC/Young Justice:

Bart Allen/Impulse: A lot of the writers treat him as naive about girls/relationships, so it's very easy to headcanon him as aro/ace. Tim Drake/Robin: Okay listen, if you ignore the fact he has a girlfriend, you can read most of 1998 Young Justice and assume he's aspec from the disinterest his has with any of the girls that flirt him him. (I also didn't know about Steph for far too long.) Cass/Batgirl/Orphan: Rule of cool.

Trigun:

Vash the Stampede: Oh my gosh I've waxed poetic about it here. But he is such a good candidate for aro headcanons. Especially the Trimax and Stampede versions. Rule of cool.

My hero academia:

This is going a while back, but my two headcanons for Kirishima Eijirou's sexuality was either aro/ace or bi/pan, with no exceptions.

Undertale/Deltarune:

Napstablook: There's so much emphasis in their story on just, connection in general. Whether familial (Metaton) or platonic (the player). Also rule of cool. Flowey: I mean, it kinda comes with the "having no feelings" territory. Rule of cool. Kris: I mean it's mainly the anti-social vibes, but also rule of cool. But it would be nice to see their thoughts without the player influence. Whether they have crushes on any of the other characters or not. I can also see them QPR/third-wheeling Susie/Noelle very easily.
