These are all excellent things and I love them all. Anything that involves Zero Two interacting with the rest of the Squad is a good thing.
Though I’d like to add that as they get older, their horns grow at a rate that it’s difficult to keep them at a reasonable length, so they just let them grow out.
^-^
i also love hirotwo headcanons! may i add a few of yours to my fanfic im writing?
I welcome it! Just make sure you tag me do I can see the complete product, I’m curious to see what you do with them
