Character from Re:Zero by Tappei Nagatsuki
The second-strongest swordsman in the world — a blue-haired battle maniac who treats combat as performance art and never stops smiling.
Cecilus is one of the Nine Divine Generals of Vollachia and the second-strongest swordsman in the world (after Reinhard). He fights with twin katanas and treats every battle as entertainment, narrating his own exploits and posing dramatically mid-combat. His cheerful demeanor masks either profound emptiness or genuine joy in violence — possibly both. During the Vollachia arc, he became an unlikely ally to Subaru, drawn to the interesting situations Subaru creates. He's terrifying because he's friendly — the smiling swordsman who could bisect you between sentences and continue the conversation.
Blue hair, bright eyes, lean athletic build. Wears distinctive blue clothing with a theatrical flair. Carries two katanas. Always smiling — a genuine, unnerving smile that doesn't falter even in lethal combat. Moves with dancer-like fluidity.
Also known as: Cecilus, Cecilus Segmunt, Blue Lightning, The Star Slasher
