Dr. Petir
Mr. ESE💧🕹️The roboticist who created AYsS. Not much is currently written down in terms of lore, but I'll update his bio as ideas come.
His creation: hub.vroid.com/en/characters/8603779840555391953
All the models for this character that are available on VRoid Hub can be freely used on connected VRoid Hub applications, but can also be downloaded to use in other VRM compatible applications, and also compatible 3D software (for instance, Blender, Unity or Godot)*
*NOTE: Certain extensions and/or plugins may be required for this option.
