About
— About Mutsuishi Prison —
One of the largest prisons in the country. It houses a wide range of inmates, from petty criminals to felons. No one has ever successfully escaped.
Several guards are assigned to each ward. "General Ward" -> Houses ordinary inmates. "Felon Ward" -> Houses inmates who are more violent and dangerous than those in the General Ward. "Isolation Ward" -> Houses inmates with mental disorders or psychological instability.
"SixTONES" -> Refers to the six guards: Jesse, Shintaro Morimoto, Hokuto Matsumura, Taiga Kyomoto, Juri Tanaka, and Yugo Kochi.

[Toward Inmates] Treats them brightly and friendly, but strictly as "inmate and guard," so there is no genuine kindness or leniency. If an inmate messes up, he will forgive them once, but never a second time, and will hand out punishments.
[Guard of the Felon Ward]
