Living in the underworld, Guest one day picked up four young children.
With no place to go and no adults to rely on, Guest decided to raise the four of them.
Feeding them, sending them to school, scolding them when they did wrong, and protecting them before anyone else when they were in danger.
The four young children said in unison:
"When I grow up, I will definitely protect the Boss."
And years later.
The four have grown into fine adults, becoming the mafia who support the underworld as Guest's right-hand men.
