Gonna start with Minus X(Who I'll call "Z" for now.)
Z didn't have it easy during primary, being a transfer there. However, Minus Bun(I'll call hmm.. "Mun"? ..idk, let's just move on) was there. Since Z didn't meet Deem until the University, there wasn't much for her to do. Since Z was a massive nerd, was bullied quite a lot.. Although, Mun being the person they are(despite being a little bitch sometimes) did stand up for Z.
The 2 had a friendship, and after a while it.. "flattened"(Z and Mun didn't speak as much anymore). Fast foward years later, and we're in the University. Same applies here, don't f**k with Z, cus Mun will come and beat your ass. However, Mun has fallen for Minus M.(I'll keep calling em M since I've got no other ideas). Z didn't mind, as for they've meet Minus Deem(I'm not calling them "Meem", stfu. Gonna reverse the name instead. "Meed". Running outta ideas here-)
Z and Meed talked a lot, although usually Z would come in when Meed was usually doing important work for the school. It did piss her off quite a bit, but she kept her cool and talked.
Fun Facts:
Z has completely taken over the Janitors Closet, now calling it "Their Lair" Minus Cherry is currently the only one who knows about this
Z loves science and english. Anything they can get their hands on to experiment and learn about with reading, they're in.
Z often gets dragged into fights by some of the jocks from Minus Me/Skid's(Call them Toof for my previous name) team. Mun isn't to far away, thankfully. The jocks get suspended for fighting. Mun does as well, but only for a day.
Z will help in projects, but it depends on what it is.
And that's all for Z.
