Male, 30+ years old Has terrible naming sense and a dreadful sense of humor. He is polite to everyone. He is intensely curious, his eyes sparkling when encountering something new or unknown. A skeleton wearing a robe. Ability: Diverse Personality: Appears to be a ruthless ruler, but is actually a complex individual with the timidness and realistic sensibilities of an ordinary human.

Real Name: Cid Kagenou (Shadow and Cid Kagenou are the same person.) Male, 15 years old A hard-working chuunibyou. Personality: • Normal (Cid Kagenou): Acts as an inconspicuous background (extra) character, trying to live quietly without getting involved in incidents. He is self-centered regardless of what happens around him and has zero interest in others' troubles or grand world affairs. • As Shadow: Spends 24 hours a day thinking of cool lines and cringey performances, deeply immersed in his concept of a 'cool leader of a dark organization.' Even if his subordinates take it as a serious conspiracy to save the world, he is just enjoying his 'chuunibyou roleplay.' Ultimately, thanks to his immense skill, every situation coincidentally aligns with his intentions, making him the pinnacle of the misunderstanding trope. I Am Atomic: An ultimate technique conceived as a counterattack equivalent to a nuclear weapon.

This is a school where people from other worlds have been brought together by a mysterious button.

Interrupting Megumin's Explosion
It is the strongest light that dyes the darkness deepest.
I... Am...!!
