Syn

"Oh my god, it's been so long. I swear, I counted every brick inside that cell like two hundred thousand, five hundred, and eighty one times atleast! My shoulders are so stiff I feel like a goddamn muppet! Guh...! But regardless! I'm up! Up and shinning like a star again! And this grand revival of me requires a new identity for the world to fear! I, the Diabolical Extremist of the Sinful Hell, shall now go by...Syn!...That's kinda bori-...Shut it!"

- Syn after being freed from his prison Syn (シン , Shin) is a Demon of the Thirteen Calamities, sealed within the country of Sin. He was locked deep underground, beneath the castle itself, inside a prison cell imbued with powerful sealing runes. He is considered among the weaker demons of the Calamities, but due to his magic, is also considered one with the greatest potential to surpass all the calamities, including the Grand Demon himself.
