History
He is renowned assassin specializing in long distance killing with over eight years of experience and a record of thirty five kills, his nickname Red Eye stemmed from his ability to take down any target and see their blood from his scope.

Plot
Red Eye accepts an assignment to kill Class 3-E's homeroom teacher Korosensei during the school trip. Karasuma gives him some anti-sensei bullets and warns him about the target. Red Eye, believing in his abilities, thinks that he is being underestimated and leaves to do the job.

Under Karasuma's instructions and with the help of the students, Red Eye sets up to snipe Korosensei when the former was having a tour on board the Sagano Scenic Railway with his students. When the train stops on a bridge overseeing Hozukyo Gorge, a student named Hinano Kurahashi distracts Korosensei by pointing at a passing boat. As Korosensei leans out of the window to look at the boat, Red Eye takes his shot only to discover that Korosensei somehow managed to stop the bullet by using a yatsuhashi. Realizing that Korosensei is not an ordinary target, Red Eye is motivated and travels to the next destination.

Later Red Eye was hunted down and killed by the God of Death.

It was later revealed that he survived as he was able to "heal fast enough because of his youth."
