Ooh! That's Duusu, peafowl kwami, of the Miraculous of Emotion. He* is a Miraculous Ladybug character. :)

*Pronouns vary, as kwami gender is complicated. I tend to say he, thanks to the AU I'm writing where Duusu has used multiple different pronouns over the centuries (magical being) and openly states that, with his present wielder, he prefers to use the male set.

This icon is of Duusu's Miraculous, the magical artifact to which he is linked. Also the one I'd wield in a heartbeat if given the chance. XD

I'm going on and on here! Whoops. :P
