The Sennyu Suit comes with Ninja Squid as the primary ability, which, being exclusive to the main slot of Clothing, prevents the wearer from also having Ability Doubler, Haunt, Respawn Punisher, or Thermal Ink. As a 3-star item, the Sennyu Suit comes with three additional slots for secondary abilities. Since it is made by the Cuttlegear brand, it has equal chances to roll any secondary ability.



  • The Team Blue of the Splatoon manga all wear the Sennyu Suit during the events of the Octo Expansion.
  • In said manga, it is explained that the pin on the Sennyu Suit turns the wearer's headgear black which is demonstrated on the Sennyu headgear set being black versions of the Blue Team's normal headgear. It is also explained that the pin also acts as a transceiver.
  • The codes for this gear expired on July 21, 2020, and therefore is no longer attainable.


Sennyu is the transcription of 潜入, a Japanese word meaning "infiltration", referencing the spy theme of the suit.
