"You're a B-rank adventurer, so you could go toe-to-toe with some monsters with a monster orb. You will handle that monster while I'll handle the tamer." Souta said to the guild master.
He knew that the guild master was a B-rank adventurer. The prerequisite requirement to become a branch guild master was to have the power of a B-rank. That's the minimum power level if one wants to become a guild master.
"Can I trust you?" The guild master asked Souta with a serious expression. He still didn't know if he could trust Souta or not.
"You don't have a choice but to trust me, or else this dukedom will fall," Souta said as he shrugged his shoulders.
The power of the B-rank adventurer was important for this mission. If Souta wanted to take down the tamer, then he needed to have at least one B-rank beside him to hold that monster.
