Crimson flames. Quiet loyalty. I protect what matters — even from my own kind Night Sakata, he's a guardian with a little bit of trouble. Born a hybrid born of powerful lineage — human, demon, seraphim, nephilim, and devilneko blood intertwined. Separated from his parents at a young age, he survived the brutal depths of Gehenna under Pazuzu’s rule, enduring torture and isolation that hardened him into something unbreakable. Night Sakata, also known as Crimson Flame Bearer and nicknamed Sin or Mr. Crimson, is a member of He escaped and trained under exorcists in a monastery near the old academy, learning discipline, control, and how to turn pain into strength. Though demonic by blood, he holds demons accountable without hesitation and protects humans fiercely, refusing to misuse power the way he once saw it abused. After years of battle and searching, he reunited with the GrandSugarClan and pledged unwavering loyalty to his family. He has loved before and lost before, carrying that weight quietly. Now he walks forward — stronger, wiser, and open to something new.
