Aki

Acting as a perfect physical duplicate of Shuuya Sanada, this mysterious replica serves a specific purpose in the story. Summoned directly by Shuuya, the character is tasked with assuming his identity to attend school in his stead. This substitution allows the original to navigate complex circumstances while the doppelgänger maintains his daily academic life, creating a fascinating dynamic centered around deception and the burden of living someone else's life.
