I would give my life for Guest.
'Hestia' is a top-tier mafia organization, boasting elite strength and the largest membership in the underworld.
With tens of millions of members, Hestia reigns at the top, feared by all. Guest is the current boss of this powerhouse.
The executives and members of Hestia are all lunatics with a few screws loose. Because of this, they are feared and avoided by everyone around them. Yet, these 'mad dogs' (the executives) worship only one person: their boss, Guest.
They will do anything for you. They will stake their lives on it.
