Hayate Kajihiro

Hayate Kajihiro (火事浩 はやて, Kajihiro Hayate) is the second-born child of the Kajihiro Clan.

Appearance
Hayate has tan skin, with messy brown hair and eyes of the same color. He is said to greatly resemble his twin sister, Asuga, in appearance. Also, his hair has an ahoge.

He tends to wear comfortable, but at the same time, tidy clothing. His favorite day-to-day outfit is a plain short-sleeved white shirt with a dull green necktie, black pants, and black shoes.

Personality
At first glance, Hayate may seem stern, but he is very friendly and approachable. He is a realist who is moved more by logic than emotion in serious situations, but still enjoys having fun and spending time with his siblings. One of his defining features is his extreme curiosity, which leads to him getting frustrated when he doesn't understand or know something, though he always has good intentions.

Hayate is a person of virtues, who values honesty above everything; because of this, he is not afraid to make controversial points or be brutally sincere when he needs to, as he'd rather do this than lie, also being unbiased. As he appreciates the truth, Hayate will not easily forgive anyone who lies to him.

Being the leader of his clan has always been Hayate's dream since childhood, but at this point in time, he has come to peace with the knowledge that it's unlikely he'll ever fulfill this due to not being the eldest child. Instead, then, he strives to help his older brother Takuya get prepared, though his offers of help are mostly rejected. Still, Hayate doesn't plan on giving up, showing a determined and stubborn side.

Background
Hayate was born as the second child of the Kajihiro clan. In his childhood, he wanted to become the clan's leader, but as he got leader, he accepted it was likely he wouldn't, and decided to help Takuya instead, though these offers were mostly rejected.

Family
Hayate has a good relationship with most members of his family.

Takuya Kajihiro
Hayate is Takuya's younger half-brother. At first, Hayate wanted Takuya's position as the heir, but eventually decided to help him prepare for it instead; even when Takuya refuses it, Hayate doesn't plan to stop.

Asuga Kajihiro
Hayate is Asuga's older twin brother. The two share a good relationship, with Asuga being able to bring out Hayate's more outgoung and fun-loving side since the two were kids. He trusts her deeply.

Naohito Kajihiro

Kitano Clan
Due to the two houses being close to each other, Hayate developed relationships with some of the members of the Kitano clan.

Kayaru Kitano
Hayate and Kayaru's relationship is complicated. Despite them knowing each other since childhood, Hayate doesn't consider Kayaru one of his friends, contrasting with Kayaru's affection for him. Hayate is often annoyed by Kayaru's trickster personality, and mianly disapproves of the lenghts he'd go just to get his attention, as well as the lies he constantly tells just to tease him. He often ignores Kayaru when in his presence, being aware that all he wants is attention.

Miyu Kitano
Hayate is Miyu's friend. Knowing each other for a long time, Hayate has deep trust in Miyu and is fond of her. Also, sometimes, he brings her candy in her house.

Lie Detector (人間のポリグラフ, Human Polygraph)
This ability greatly improves Hayate's perception and senses, and thus, allows him to notice when someone is lying more easily through their behavior (such as sweating, moving too much, breathing quickly). The ability is not fully mastered yet, however, so it is not 100% accurate, as external factors can affect it:
 * If someone is merely nervous when talking about something, this can confuse the ability and make it look like the person is lying.
 * It only works with deliberate lies, and thus, if a person truly believes false information, it won't be counted as such.
 * A more experienced or casual liar can end up fooling the ability.

Trivia

 * Hayate's name "wind", matching with his twin sister Asuga's name, which can mean the same.
