History
Before becoming an assistant to Teppei Sasaki on the manga White Knight, he made a debut in Jump with a one shot and was an honorary winner of one of Shonen Jump's monthly awards.

Synopsis
Igarashi is introduced as a one of the 4 new art assistants working to make the White Knight manga a reality. Upon meeting Sasaki, he states that he respects him and that its a pleasure to meet him.

A few days after the initial meeting, Igarashi and the other assistants are on the way to the studio in order to check on the progress that Sasaki had made on the 54 page first chapter, only to find that the room he's in unbearably hot, comparing it to a sauna.

After Sasaki tells them that he hasn't completed the pages, and wants to redraw them, while Genki is enthusiastic and believes with enough guts they can make the deadline, Igarashi is more pragmatic, saying that they cannot afford to miss the deadline for the first chapter of the series.

Once Sasaki finishes the redraw, he is seriously impressed the, saying that the greatest of all time is born. However when sasaki rips up the redrawn chapter in front of them, claiming its not good enough, the shock to him and the rest of the team is immense.
