Irewig (Japanese: ムカムカデ Mukamukade) is a Rank D, Fire-attribute Yo-kai of the Slippery tribe.

Irewig evolves into Firewig starting at level 26.



Irewig has the appearance of a centipede with a dark blue chitin and a yellow underbelly. His face, four arms and legs are orange, and has glaring eyes with light-blue sclera and sharp teeth with two prominent red fangs. He has red antennae that are somewhat jagged close to the end and an orange pincer-like pair of legs that with red tips on his tail. He also has red feet and straw sandals.

Irewig has a fierce and wild personality, which he passes onto the victims he Inspirits.

Anyone Inspirited by this Yo-kai becomes easily ticked off and prone to bursting into angry rants about even small, insignificant grievances. In the anime, Irewig does so by using the two legs on his tail to pinch his victims, making them angry.

Irewig himself is also easily ticked off, as seems to get angry for every cation done to him in almost every game. He can also multitask, as the anime shows.

  • "Irewig" is a portmanteau of ire (anger) and earwig.
  • "Scoltine" is a portmanteau of "scorpion" and "coltine" (put up with)


Irewig's based on the mukade or oomukade, a youkai born from the Asian red-headed centipede. Aggressive and with a painful bite, much like the actual centipede, it only differs for its massive size. Its weakness is human saliva.


Receiving food (favourite): "Grrr! Too good!" Receiving food (normal) "Not enough flavor!" Receiving food (disliked): "Argh...why?" Loafing: "Are we done yet?" Traded (YW2): "UGH. What am I doing here now?!" Befriended (YW2): "Maaan, I lost... Be my friend and we're even!" Traded (Blasters): "Where am I!? This place looks forelorn! It's irritating!" Befriended (Blasters): "I lost... Uh... How irritating! I'll be your friend and get revenge!"


  • Despite being a Yo-kai based on a centipede, translated ports and dubs name it after an earwig or a scorpion.
  • Irewig is the counterpart to Zappary. Both are D Ranks that evolve into A Ranks by levelling up, their evolutions accompany the said Yo-kai's clan leaders during battle and take charge in the present era.
  • He actually only has 8 legs although he is a centipede. Centipedes have between 30-324 legs.
