Around 23 with personalities, names, designs and all that (well, except a couple parents I haven't drawn yet). There's more people that I know exist in my story but I'm not counting them until I know them x'D
All of them exist in the world of my comic, although not all get to actively appear in it. Around 15 of them will appear in the comic (even if it's just in one panel).
I tend to focus way more on develop my characters a lot than in making new ones, I literally don't know how people can keep track of 100+ characters >.>"
