Maiko Plasma (舞妓プラズマ, Maiko Purazuma) is one of the two Monster Association monsters assigned to attack D-City.


Maiko Plasma appearance is that of a Maiko with her black hair tied up in a traditional Japanese way with many decorative hair clips with stars, clouds and thunderbolts. As a Maiko, she wears a long kimono called hikizuri with cloud and thunderbolt printed on it and a black obi sash with two belts tied over it and wearing wedge heeled wooden sandals. Around her, she has eight Tomoe drums attached to her back and carries two drum sticks in her hand.


Maiko Plasma seems rather calm and acknowledges that there are more powerful beings than her in the world, a trait very few low level threat level monsters have.[1]


Human Monster SagaEdit

Monster Raid ArcEdit

She and Electric Catfish Man go to attack the recently rebuilt D-City. At the city, they encounter Lightning Genji. Unfortunately for Lightning Genji, their attributes nullify his stun attacks.[2] The monster pair eventually defeat Lightning Genji.[3]

In the Monster Association, she and Electric Catfish Man are discussing their victory over Lightning Genji and remarking that it was thanks to Gyoro Gyoro and her carefully-planned choice of who they would fight that the pair won against the A-class hero.

  • A Maiko (舞子 or 舞妓) is an apprentice geisha, while Plasma is one of the four fundamental states of matter.
  • Maiko Plasma in Japanese stands for Mycoplasma from Mycoplasma Pneumonia.
  • The drums attached to her are likely a reference to Raijin, a Shinto storm god, who is often depicted with having similar drums attached to him to create thunder.
