Gerald Walker is the half older brother of Usui Takumi through their mother. Gerard is 1/4 japanese, but despite the bloodline difference he and takumi have, a striking resemblance regardless of their different fathers. He first appeared in chapter 50, Misaki mistook him for Usui due to the uncanny resemblance. He and Takumi appear to be in bad terms, perhaps due to the fact that Takumi is the illegitimate child of Gerard's mother.
Unlike Takumi, Gerard is not good in cooking. It seems the only difference between the two is their hair and their personality. At the end of chapter 51, it is revealed that he is up to no good and commanded his bodyguard Cedric to fulfill his evil plan. Takumi is aware of this, as Gerard said: "I think a dog running away from discipline must have its bones crushed to pieces."
Like Takumi, he appears to share the habit of teasing his friends, as he teases Cedric constantly.
He dislikes Japan for its dislike of smokers, though he does like the cheap cigarettes. He is a chain smoker.
- Enjoys apples.
- He likes teasing Cedric, or 'Ceddy' as he calls him.
- He can't cook or possibly unable to use knives.
- Like his brother he is bilingual in both of his blood-related cultures ( Japanese and English). Misaki even comments how fluent he is in Japanese.
