Appearance
Nishigaki has olive, braided hair and he ties them on the back with a low pony-tail. He has black eyes and dark skin. His hair style is similar to that of Kidou Yuuto and Demonio Strada. He also wears a blue headband like Endou Mamoru's.

Season 1
He is first seen in one of Aki's flashback, when him, Ichinose, and Domon are trying to perfect Tri Pegasus.

Then, when Raimon's match against Kidokawa Seishuu was decided, he was seen with their coach and the Triangle Z-triplets. Ichinose, Domon, and Aki noticed him and so they decided to stay and chat together like the old times. He told the three that he had joined Kidokawa Seishuu's team but was surprised to see his three childhood friends on the rival team. Ichinose told him that he, Domon, and Endou had perfected their own Tri-Pegasus and he was surprised. Then he departed from them.

During the match against Raimon, when he saw the Tri-Pegasus, he told Ichinose, Domon, and Endou that they had truly made it their own technique. And when the match was over, after seeing Tri-Pegasus evolve, he named the new technique "The Phoenix."

Season 2
He was seen as a member of the Dark Emperors with a piece of the Aliea Meteorite. Ichinose exclaimed that he was surprised that Nishigaki was there and had a flashback to when he met Nishigaki at the riverbank — Nishigaki using Spinning Cut on Ichinose, Domon, and Endou to block The Phoenix.
