Kido Master- Skilled with Kido, Kosatsu has shown to use up to Level 60 Kido. He has often conjoined Kido, making them stronger. He regards Kido as one of the strongest of Shinigami's skills. His favorite and most used Kido has shown to be Byakurai.
Shunpo User- Not as adept with it as he wants to be, Kosatsu is somewhat skilled with Flash Step. He uses it to move around, but tires out quickly.
Natural Water Affinity- His natural affinity has shown to be water. He has a special ability to control water to a certain degree with the aid of precise chakra control. It seems to stem from his Zanpakuto's Water/Kido nature.
Kosatsu's Zanpakuto is called Ningyo (lit. Mermaid). It is sealed as a nodachi with a blue handle and square guard. The edges of the guard each have an indentation, giving it and arch like shape. The release phrase is Lure.
Shikai- In Shikai, Ningyo becomes a long khakkhara that is entierly gold. At the top end of the staff, there is two hanging gold rings. At the butt of the khakkhara is a thin blue ceramic ball with a thin strip going through the middle. The only ability shown is to be water control.
