Ikustan

ikustaN is a being supposedly from the Shadow Realm and the partner of Yajin Niroku. She has black eyes and pink hair.

History
Ikustan was born in the Shadow Dimension and became a founding member of the DDC. One day, a rift opened and exposed the DDC to light for the first time. This caused Ikustan to get the desire to break people's necks, and she also got the ability to conjure barbecue skewers whenever she pleases.

Ikustan fled from the DDC after Riyu went mad from the light and killed Iroyas and supposedly killed Akinom (Akinom survived). She was found by Yajin Niroku, and the two of them formed a partnership.

Yajin Niroku and Ikustan then broke Lord Nemesis out of Darkprism, but then the two of them betrayed him after. Ikustan began a heated rivalry with Natsuki, who became Anti-Kuroninja's apprentice to learn the power of The Void to stop her.

Later, Ikustan was killed by Lord Nemesis, which caused Yajin Niroku to fight against him.

Personality
Ikustan enjoys grilling barbecue skewers on her grill. Sometimes she uses these barbecue skewers as explosive weapons. She also leaves barbecue skewers next to her victims as a calling card.

One thing that Ikustan has an unhealthy obsession with is breaking peoples’ necks, up to the point where Yajin Niroku is annoyed by this.

Trivia

 * Her name is “Natsuki” spelled backwards. This may or may not be a reference to DDLC, but it’s very likely, since Kuroninja’s Earth-0 Counterpart created Ikustan, after all.
 * Ikustan might’ve been inspired by Natsuki’s corruption during act 2 of Doki Doki Literature Club, where she had black eyes in some scenes.
 * Ikustan’s obsession with breaking peoples’ necks is a reference to the infamous scene in DDLC where Natsuki snaps her neck.
