Kai lied. He was a liar. A big fat liar. He didn't stop at 9 more quests to build synergy, no, he continued his "team bonding" quests for the whole week, making his girls take on ten A-Rank Quests a day for 7 days straight. All of this was in the name of building synergy.
His girls understood his intentions and were glad that he was taking the time to help them out while also building up their Party quest resume, which would allow them to rank up sooner. But it was pure torture taking on so many difficult quests without Kai's help.
"That's it! You got this, girls! Push it! You're at the final stretch!" Kai shouted, his encouragement pissing off his girls even more than they were.
"AHHHHHHHHHH!!!" Amaya slashed her sword vertically, cleanly cutting a wyvern in half. That's right, she was able to kill a wyvern now.
