Takashiro Giou

Takashiro Giou serves as the leader of the Giou clan and initially appears as Yuki’s long-lost older half-brother. He has survived for over a millennium by using a forbidden ritual involving a dura, granting him immense regenerative abilities and knowledge of the eternal war's secrets. Driven by the conviction that victory demands significant sacrifice, he manipulates the reincarnations of the Zweilt Guardians to fight Reiga. Despite his deceptive history and complex relationship with Yuki, he remains a central figure in the ongoing conflict.
