Ryuki is a high school student who appears as a minor antagonist in Assassination Classroom during the class trip. He is so slight a figure that the source material barely acknowledges him, even joking about whether he genuinely exists.
Ryuki is drawn with brown eyes, lightly tanned skin, and dark hair combed straight back.
As a fleeting antagonist, Ryuki is given no real characterization in the source material. His presence amounts to a brief turn during the school trip rather than any developed personality.
