Kairai Kugurugi (潜木 怪儡, Kugurugi Kairai) is a member of the Shiranui Household affiliated with the Kugurugi family, and the double of Mogura Kugurugi.
Kairai is, by his own admission, a pervert who enjoys being stepped on, even going so far as to insist Medaka Kurokami step on him every morning once they are married. He is quite malicious, as he eagerly taunts Medaka about the death of Fukurou Tsurubami, even with Kamome Tsurubami standing right next to her. According to Tsurubami, Kairai and Gizou Yuzuriha both have a bad aura, the worst among the doubles.
Kairai often has his eyes squinted. He has dark red hair tied in a long braid, except for a thick strand that hands down in front of his face. He wears a white, fur-lined jacket on top of a dark shirt. He wears wrist bands and has a thick sash around his middle. He also wears striped, violet trousers and purple boots.
Kairai was originally born from the Shiranui family, before becoming a part of the Kugurugi family.
Jet Black Bride Arc
Kairai is lying on the floor of the aircraft carrier Black, hoping to be stepped on by Medaka. She manages to avoid him, after which he sits up and apologizes. After Tsurubami accuses him of being a pervert, he accepts the label as a compliment, and reveals the other suitors waiting behind him are perverts as well. Listening to Medaka, he tells her to insult them as much as she likes, but reminds her that she will be marrying one of them. He then tells her that once they are married, he will have her step on him every morning. Kairai taunts Medaka about the death of Fukurou Tsurubami; before she can lunge at him, Bukiko Udou gets between them. Kairai listens on as Udou explains the rules of the second Jet Black Wedding Feast, and asks Gizou what order they should go in. Kairai is the first to battle Najimi Ajimu, stating he will defeat her in five seconds. However, he is easily defeated by one hundred of Ajimu's sword skills. As Kairai lies defeated, it is revealed that he and the others are actually nothing more than doubles for the real suitors.
Unknown Shiranui Arc
Kairai lies on the road in wait for Medaka and her group, and expresses his disappointment when Ajimu stops their jeep without running him over. At Misogi Kumagawa's comment that he has recovered well from Ajimu's beating, Kairai reveals his true weapon is a revolver…only to be defeated by Ajimu once again, this time with a hundred gun skills. Bloodied, Kairai rises to his feet, explaining that he was sent to act as a guide, and welcomes the group to Shiranui Village. Having to abandon the jeep due to the terrain, Kairai leads the group on foot. He tells Medaka that her former suitors are doing well, though Momo Momozono is still depressed. Asked by Zenkichi Hitoyoshi if he is happy as a double, Karai can only answer yes, as he is still fulfilling his role. He suggests Zenkichi ask Hansode Shiranui, who has already finished her assignment. At a three way branch in the path, Kairai explain the group has to choose the correct route on their own, explaining that his purpose as a guide was to guide them back. After Medaka picks the correct path, Kairai comments that he can see why his lady lost, but mentions the problem is not bringing Shiranui back to Hakoniwa Academy, but whether she wants to return. When Obi appears before the group, Kairai moves to stand beside her. He brings up the rear as the group moves through the Shiranui Village. He stands beside Obi as she administers the last test. Kairai is pleased with Shiranui's response to her friends, remarking that it seems there was no need to worry. At her friends' refusal to leave however, Obi orders Kairai to bring them tea. Kairai questions where she is going; Obi tells him she will be checking on Iihiko Shishime. After serving them, Kairai stands behind and away from the group.
When Medaka acquiesces to Ajimu's order to flee, she takes everyone else in the room with her, knocking out Kairai in the process. Medaka carries the group to Ajimu's jeep. Kairai and Obi observe Medaka as she enters Altered God Mode to fight Iihiko. When Iihiko takes Zenkichi's glasses to use as a weapon against Medaka, Kairai notes that Iihiko is starting his game. After Iihiko breaks Medaka's torso, Kairai states that the fight and Medaka's fighting career are both over. With the arrival of the members of the Thirteen Party, Kairai expresses his surprise, not recognizing them from the Jet Black Wedding Feast. He is shocked however to witness their combative abilities. Kairai is mystified by the behavior of Oudo Miyakonojou and Mizou Yukuhashi, but awed by their Abnormalities in action. He is amazed when Iihiko is knocked of the mountain by a stealth armored truck. After Medaka and company escape, Kairai and Obi climb back to solid ground, Kairai wondering who could have been driving the truck. Sometime later, Kairai and Shinkirou Kotobuki transport Shiranui to her next workplace.
The three arrive at the ruins of Hakoniwa General Hospital to meet Fukurou. Kairai questions whether Fukurou will really be waiting for them. Listening to Shiranui, Kairai asks about Hato Tsurubami. After hearing Shiranui's explanation, he questions why Kajiki Kurokami would marry such an unsociable person. Arriving at the director's office, Kairai and Shinkirou both insist that they stick with Shiranui for a while longer. Upon entering however, all three are trapped in a cage. Kairai is horrified when Fukurou uses his styles to kill Shinkirou and seal his body in a name card. He becomes more and more confused as Fukurou reveals the extent of his research on Shiranui. He is shocked when Fukurou proposes to Shiranui. He is disgusted to learn that Fukurou purposely arranged Hato's marriage so that he could go after her daughter, and is further repulsed by Fukurou's methods to capture Shiranui. In a last attempt, Kairai reminds Fukurou of the threat presented by Iihiko. Kairai is surprised to hear that Medaka has come to the hospital, but realizes that it is an excellent opportunity for himself and Shiranui to escape. He is shocked however when Shiranui requests that Fukurou keep Medaka away. Asking if she still intends to act as Medaka's double, he is surprised to hear Shiranui's melancholy.
Kairai is still imprisoned when Tsurubami and Namanie Nienami arrive at Fukurou's office. He is shocked to see Tsurubami defeated. When Fukurou reveals that his son was just another of Fukurou's failed attempts to create a gentler Hato, Kairai loses his temper and calls out Fukurou on his behavior. He is shocked to see Fukurou's death with the arrival of Iihiko. With Tsurubami's explanation, he remembers Fukurou's behavior towards Shinkirou. Kairai is surprised by Medaka's appearance. He recognizes Medaka's preparation for the Kurokami Phantom, but is confused as the same move failed in the Shiranui Village. Kairai is horrified when Medaka falls. Kairai is amazed when Medaka regains consciousness and rises to her feet. He is further shocked to hear Medaka is using the same method Fukurou used to survive after being stabbed in the heart three years earlier. Kairai watches on as Medaka launches herself at Iihiko. He is surprised like everyone else by Medaka's clone gambit. When Iihiko dodges, Kairai is appalled. He is shocked when Medaka strikes Iihiko from behind. Kairai and the others are protected by Medaka as Iihiko destroys the hospital. Kumagawa and the others are attacked by Iihiko; the attack proves fatal. With his defeat, Iihiko's damage becomes reversible, and Kairai is healed by Medaka with the Five Forks. He wonders if Obi is calling Kumagawa about Iihiko's defeat. After Kumagawa knocks out Medaka's friends, Kairai carries Shiranui.
Bouquet Toss To The Future Arc
Kairai confronts Medaka at Hakoniwa Academy as part of the 100 Flowers Run, along with Iihiko and the rest of the Shiranui family. Medaka defeats Kairai with her End God Mode and ninety-nine trample skills. His message to Medaka is a thank you for helping Shiranui.
Ten years later, Kairai works in the now public Shiranui Village.
