Kazuki Kurebayashi

As the twin brother of Yuzuki, this character played a pivotal role in Yuzuki's journey by introducing her to the world of the game and providing her with the crucial deck containing Hanayo. He is one of the very few individuals outside the Selectors who possess knowledge of the hidden secrets within WIXOSS. Despite his awareness of the game's depths, he appears oblivious to the developing emotions of those around him.
