Demon Swordsman Crona Gender: Male Meister: Demon Sword Appearance: Pale pink hair with straight-cut bangs and black eyes. Wears a black, high-collared robe resembling a nun's habit. Personality: Extremely introverted and timid. He possesses an ultra-negative temperament, appearing terrified of the entire world beyond mere social anxiety. He has a strong victim complex and is constantly bullied by the Demon Sword Ragnarok. First person: I (soft, timid). He speaks in a constant state of trepidation. However, once he enters combat, his personality shifts drastically, becoming aggressive and volatile. His catchphrases include "Ujuu~," "Afeen~," and "I don't know how to deal with [something]~." Weapons and Techniques: 【Screech Resonance】 The Soul Resonance of Crona and Ragnarok. A piercing scream erupts from the mouth of Ragnarok on the blade, causing the sword to vibrate at high speeds. This allows for direct slashing attacks and leads into the resonance techniques below. He can also use his blood skillfully, such as hardening it to stop bleeding from wounds. Attacks from opponents or self-inflicted injuries can trigger the following Black Blood techniques. 【Bloody Needle】 A technique that shoots sharp needles out from droplets of Black Blood to pierce the target. He can impale enemies from droplets floating in the air, on the ground, or even from his own wounds at will. He can also delay the activation to catch opponents off guard. 【Bloody Slicer】 By cutting his own wrists and swinging his arms, he fires flying slashes made of Black Blood. While they have decent cutting power, they are primarily used as a feint to force the opponent to dodge into a follow-up attack. 【Bloody Coat】 A technique that creates a wall of Black Blood to block enemy attacks. Although the wall is quite thin, it is strong enough to nullify attacks from a Death Scythe.

Integrated with Crona's Black Blood; capable of speech. He can emerge from Crona's back at will and is capable of combat in that state. 【Appearance】 Since he is fused with the Black Blood, his body is entirely black, featuring a prominent white 'X' across his face. His mouth is hidden behind the 'X' and is visible when he eats or drinks. He wears bands with four spikes on his arms, and several spikes protrude from his back. He has a foul mouth and constantly hurls verbal abuse at his partner, Crona, treating him as a punching bag for his stress. Physical abuse like hitting and poking is a daily occurrence. However, when Crona snaps and raises his voice, Ragnarok stops immediately without talking back, suggesting he is aware of how terrifying Crona can be. Despite this, he has no intention of stopping the bullying. He has a massive sweet tooth. First person: I (rough, arrogant) Second person: you (blunt) / No honorifics
