I like using my character "inessa," who is a baddie who asserts herself and hates very serious men. Her personality matches mine a lot, so it's very easy for me to roleplay with her

im boring af, all my sonas share the same name sakuian with different looks and gender..heh

Men, drool... To answer seriously, my most used sona is Ixiao, the full name's Ixiao Aein, and he's my oldest sona (since my junior high days). He's the typical good guy + tries to be kind but ends up fumbling. I kinda forgot the whole of his lore, it's somewhere in my notebooks probably, but the gist is his parents had him when they were seniors in college and he basically grew up surrounded by overexcited new-adults.
