Yonei

Yonei once impersonated Dan to gain fame and steal his life. He was Dan's classmate throughout junior and senior years, driven by jealousy due to his own loneliness and feeling like a nobody. He entertained the idea of assuming Dan's identity to escape his own reality.

However, when Dan uncovered the truth, a fight ensued which resulted in Yonei's right side of his face being burned.

Out of defeat, someone eventually offered their hand and invited Yonei to the "League of Nefarious," where he becomes a full-time evil spy in the agency.

His appearance remains similar to Dan's but with differences, including blonde hair, a prosthetic eye resembling a sniper's aim, freckles, and burns. Yonei also wields a scythe as a weapon.
