Kapitel 1948: Final Support 

When he heard Argy's 'proposal,' something he couldn't refuse or he would surely be devoured on the spot, Minos understood almost immediately what the dragon leader of this tribe had in mind.

'Even if there is no threat to our world, if I reach the end of the 10th stage, your tribe would have an ally with some sensitive obligations towards you...' He thought for a second.
