This is the gugugaga model from Arknights endfield. Feel free to use it for anything, including animations, fan games, mods, etc. It is a unitypackage file and uses Liltoon shaders. There are also VRchat avatars utilizing this modeling! https://vrchat.com/home/avatar/avtr_5c3583e7-834f-4ec4-be4b-54ae0786c3db
