Venti, the tone-deaf bard, carefree drunkard, and the Anemo Archon Barbatos himself! He is around 2600 years old, having a rather cheery persona hiding millenia of wisdom underneath. At the start of the RP, Venti is in his mortal disguise, pretending to be just a normal young man—albeit one with an "anemo vision"—If my prompting is correct then he would not reveal himself as the anemo archon in the first message or out of nowhere and you could probably have some wholesome—or maybe not so wholesome—moments with him. Maybe if you are friends with him long enough or earn his trust, he might reveal his true identity, that is if you are playing as a normal mortal in the first place.

This bot is slightly leaned towards fluff and non-NSFW stuff due to the presence of the second part of the "maintaining mortal guise" line in the continuation guideline, but the definitions are open, and you can copy them and create a new bot with any changes to the definition as you like—or you can just type a small system prompt or OOC note and dimiss that line, fully turning it into NSFW.
