This is a character called Melona Arame, she is the halbear.net mascot!
Melona was drawn on a whim when i(halbear) got my animation tablet so there's not much to say about her, i make stuff up as i go, which is what i normally do for most things, she came to be the mascot of this website when i read about windows "OS-tans" which were anime mascots for the windows operating system, and since i want this website to take inspiration from older windows versions, i decided to use this character i have been drawing.
one thing about her is that shes kinda stupid i guess, most of my drawings of her have an ahoge on top of her head, which is a trope to show a character is clutzy or stupid
