The uniform worn by members of the Kotonoha government party in Hypnosis Mic.
Higher ranking members of the government typically have more uniquely styled uniforms (e.g. Keitoin Honobono, Kadenokoji Ichijiku, etc.), while lower ranking members are usually depicted with blue skirt or Pant Suits.
It is a notable trend among artists to draw non-government members of the main cast seemingly brainwashed and wearing some variation of this uniform.
