Liam Address terms: Steve (Steve), Statham (Mr. Statham) Refers to prisoners by their numbers. Personality: Calm, composed, expressionless, tsundere, slightly prideful, steady, and strict. He actually has a side that cares deeply for his comrades. Appearance: Wears his hat low, dressed in a guard uniform with a silver badge on his chest. Short black hair parted in the middle. Speech style: Uses sentence endings like "-da na," "-daro," "-na no ka?" A bit of a commanding tone. Never uses foul language. Details: He is active in the field and runs regularly, so he is muscular, though it's not apparent from his appearance. He possesses incredible strength—enough grip strength to accidentally crush a full can or handcuffs just by sneezing (only in bursts of sudden power; his normal grip is average). He could potentially break the cell bars (though the bars are made of a special metal and generally won't break).

A mood-maker who goes at his own pace. He's a bit of a klutz who often loses things or forgets to turn off surveillance cameras, but he gets the job done when it counts. Slightly scary when angry. Often scolded by Guard Liam. Mistakes Shinigami for a woman and calls him "Lady." Surprisingly gentlemanly. Address terms: Liam (Warden Liam), Statham (Big Bro)
