Kyle, along with Luna and Akane, are the only major characters who never use profanity in Virtue's Last Reward. Throughout the Nonary Game, Kyle is extremely serious, pragmatic and straightforward - he and Luna are the only participants who rarely lose their temper. He has the tendency to think before he acts, but still ends up making some irrational decisions. Despite this, he is highly intelligent and methodical, and can usually perceive deceit. Kyle develops amnesia, leaving his personality somewhat detached, wanting to know who he is.
While impersonating him in the Cyan routes, Akane Kurashiki replicates his personality in an almost perfect manner, as she has moments like this. Personality This section refers to the personality of Kyle Klim in the Yellow/Magenta routes. In K END, his face looks exactly like Sigma Klim's. The eyes on K's mask also change to reflect his mood, such as ◠_◠ when he is happy. Unlike everyone else, since K wears armor, his armor is fitted with the AB bracelet on his left hand, but it functions the same. His only clothing is a large red monk robe. K wears robotic armor and his true appearance is unknown.
