Yuuki Naegi's Links
Hayabusa gets the brunt of their hatred. While it’s usually the older sibling bullying the younger, the roles are reversed with these two. Even with Hayabusa’s size over Yuuki, they still manage to win their fights, even with Hayabusa’s own skill in fighting. Yuuki believes that there’s a constant competition between the two, and that Hayabusa’s winning, leading them to be angrier and more spiteful at their brother.
Tsukiya was often more of an older brother to Yuuki than Hayabusa was. He was always treating them with kindness and respect when he came around to hang out with Hayabusa. After his falling out, they still kept them close. However, he began to feed into their hatred and jealousy of Hayabusa, making them more aware of the supposed favoritism he got from their moms. Still, he cares for him deeply, and their death led them to a breaking point to try and end the game, even though it cost him his life.
