1 main and technically 5 sides. I only really keep two accounts connected to the main as sides the rest are fluid depending on what I'm up to and subject to change depending on what is where.
The 5 sides are legit made by me when I was young. The main is something I switched to because I liked the UN and dubbed was always a side. I got it as a shell when I bought a UC and it was just too fitting for me to let go lol.(Though seriously IDK how the f my original main became the main name wise I always wanted to move anyways.)
Let's see. There's my main, plus three side accounts. Two shells, a backup main, and one I forgot the info for but I know I have lying around somewhere. So 8 total I think? I've had more, but gotten them frozen for whatever reasons.
