Crimson Sage; Rebirth

Born into the tragic Uchiha clan, Ikari Uchiha was the middle child between Itachi and Sasuke. On the night of the massacre, he watched helplessly as his beloved brother slaughtered their clan, forever burning the trauma into his eyes - awakening his own Mangekyō Sharingan.
Years later, trying to escape his pain, Ikari joins Rias Gremory's Peerage as a Pawn after being reincarnated by her. For a time, he finds peace and purpose among them, protecting his new family with the same loyalty that once defined the Uchiha.

But when Issei Hyoudou enters the scene, the world turns upside down. The same girls Ikari fought for - even Rias herself - fall for Issei, leaving Ikari forgotten, his sacrifices erased by their obsession. His heart shatters, and with it, the last of his trust.

Right before the Riser Phenex arc, Ikari disappears.
No one knows that he cast away his Pawn piece, cutting Rias's link to him forever.

For a year, he travels the world with his brother Sasuke, mastering all elemental jutsu, senjutsu, and techniques of legendary shinobi - from Minato's speed to Madara's power, from Naruto's heart to Kakashi's cunning.

He returns not as Rias's Pawn... but as a legend whispered among Devils, Angels, and Fallen alike - the Crimson Sage.
