Youkyo is a Mexican vtuber who plays shooters most of the time, but sometimes tends to try all kinds of games, reacts to videos sent to him, talks about his life and focuses his content on multiple things like drawing, singing sometimes, and several other things.
He also speaks English, albeit somewhat basic, but always tries to pay attention to his chat to make them feel part of the stream.
He was previously known as Zadkichan but apparently had a rebranding somewhere in March 2023 leaving the previous content and creating a new channel since then.
Youkyo's lore is still largely unknown, he occasionally talks about his story through the streams to give some details, he says he has worked on it but doesn't feel confident to show it yet.
But in summary it is the story of an individual who inhabits a place known as the citadel, belonging to something known as the order and secrets that exist in this place/dimension known as the void.
