SY3 is a content creator who streams whenever he can. He mostly plays games that range from turn based games to FPS to indie games. He tries his best to provide a stream that you can lurk in and have on in the background, so there are really cozy vibes. SY3 use a pre-made Live2D model. He is currently working on a personal design and will hopefully have one soon.
SY3 is a speech-to-text creator. This means he doesn't use his voice and instead uses captions to communicate with his audience. He can have captions in different languages, but he only speaks English. This is the language he uses for captions as well.
SY3 is a guiding entity that helps Flashes (lost souls) to pass on since they seem to still be here due to their overwhelming desire for something. That could be something as simple as a child's toy or more complicated like an abstract concept. It's all by a case by case basis.
He does this mostly through old TVs since he can't leave the digital space at the moment. It's easier to fabricate a world for the Flashes to get their desire fulfilled that way. Of course he has help from the Lost Ones (viewers) which are little white, glob like creatures?...souls?...no one really knows what they are. They just seem to like SY3, so he entertains them as thank you for their help with his job. He does this mostly by taking them to games (where he can control the character) or letting them watch things or chatting with them in his digital space.
