The Janitor Is A Mob Boss

Once the most feared underworld sovereign in the country, a retired kingpin abandons crime entirely to work as a humble school caretaker, yearning only for his daughter to grow up free from bloodshed. He tolerates daily disrespect and keeps his violent past buried beneath worn overalls and quiet smiles. However, when vicious rivals track down his whereabouts and torment his daughter to the brink of catastrophe, the aging custodian can remain passive no longer. Shedding his meek persona, he summons his underground connections and unleashes terrifying retribution upon every criminal daring to threaten his kin.
