Here is the rest of Izaak's system!

Vix (he/him) is a more analytical guy, he wants to do actual experiments, and is annoyed by Izaak's lack of scientific method.  Annoyed by everyone really.  However, the experiments he wants to do are unethical, and he doesn't care about the well-being of test subjects.

Staples (they/them, she/her) is a very promiscuous entity, they are an incubus/succubus.  They are very forward to a fault, too bold and careless.  They are really playful and like to make jokes/poke fun.

X-y-z (he/him) is really sad and anxious all the time, he is the most caring but also the most wary and untrusting.  He just wants to be a chemistry professor.  He wants to help people but he doesn't feel capable of that, and he cries a lot.  He likes to read.

They all have different body language and glasses wgen fronting to use the body (I have a sketch I will post later).

I hope you like them!! It's really important to me to have system characters, I don't see them very often in media and the ones I do see aren't that relatable to me usually!

Also Staples is wearing pasties to cover their nipples but I will tag it anyway just to be safe lol
