Hmmmmmm... dunno how I feel about this topic... I'll see how people react I guess. I would suggest adorable character (or adorable human) might be a better way to go. I mean, it's not like there's anything wrong about this, but I can see it devolving into an argument about gender stereotypes.
That being said, Ribbon from Kirby Crystal shards is adorable. Edea from Bravely Default as well... she doesn't quite fit what you'd normally consider adorable, but the chibi art style in that game makes everyone cute. Also probably Colette from Tales of Symphonia, and Bernie from Fire Emblem Three Houses who is adorably awkward.
