List of Hayate The Combat Butler Characters - Segawa Household

Segawa Household

Izumi Segawa (瀬川 泉, Segawa Izumi?)

Voiced by: Sayuri Yahagi

Izumi Segawa is the student representative for Hayate's class at Hakuō Academy. She is the younger fraternal twin sister of Kotetsu Segawa. She met Hayate when they were younger (volume 17 flashback) as she was getting attacked by a dog and gave him a kiss for saving her, as well as telling him she would be his bride when they're older; although she mentioned nothing about that incident when she first met Hayate at Hakuō Academy, possibly due to both parties not remembering each other. Like her friends, she addresses Hayate as "Hayata". Izumi gets along well with Hayate, and is comfortable enough to even change clothes while he is in the same room (though not for him to actually watch her change). Later on, she realises she may have started to develop feelings for Hayate. She calls herself as member "Red" of the Hakuou Three Amiga.

Kotetsu Segawa (瀬川 虎鉄, Segawa Kotetsu?)

Voiced by: Go Shinomiya

Segawa Kotetsu is the combat butler of the Segawa family and the older fraternal twin brother of Izumi Segawa. As a running gag, his hobby is his extreme love of trains and train turntables. He seems to be shy as he has never had the confidence to ask a girl out. It seems that his terrible luck with women has left him feeling bitter about the entire female gender, but while he is at Hinagiku's birthday party, he runs into Hayate and immediately falls in love with him, or rather his alter-ego Hermione. He soon learns of Hayate's identity from Izumi. Angered by this, he kidnaps Nagi in order to bring Hayate out. After Nagi confronts him on his shallow attitude towards love in general, he vows to change his attitude and still loves Hayate even after discovering that he is male. He seems extremely hung up on Hayate and uses various methods to try to spend time with him, such as challenging him to ping pong to get him to spend time in a hot spring they were both visiting. He is rarely seen in the first season of the anime, making brief appearances once in a while, although Izumi has referred to him several times; he gets a larger role in the second season. Kotetsu is the only person whom Hayate really hates (besides his parents).

Stringer Segawa (瀬川 ストリンガー, Segawa Sutoringā?)

Stringer is Izumi and Kotetsu's father. He is very protective of Izumi, particularly against males, to the point that Izumi must smuggle Hayate in as a girl, though the truth is later revealed. He does not appear to care much for Kotetsu, betting his life against Hayate's in order to gain Izumi's hand in marriage.
