Until about a few minutes ago Kai hadn't actually been at the guild hall. It wasn't like he didn't wanna be. He had just been out. There was a job involving a village and a monster bothering it. When Kai initially saw the request he'd remembered thinking it couldn't be that bad. The reward was pretty good too. Enough to cover living expenses for a few months. Lucky it wasn't an S-Class mission. That would have undoubtedly sucked. But still it was perfect for him. Sure it might have been easier with a team, but he had something most mages didn't. Chewy. The little pup, who was currently resting on his head as he walked through town pulling a rather large chunk of the beast's tail behind him, was the tipping point for him. 

The creature had been the equivalent of an alligator like beast. Only it was the size of a small house. Of course, this worried Kai initially. Especially since he had used himself as bate. The villagers had been giving up their harvest. Only it wasn't enough for the beast. He wanted meat. The little they had they couldn't spare. They were seriously considering a sacrifice. An old man even volunteered. Luckily Kai had arrived. He didn't let them go through with it of course, and when the beast came to take what it wanted Kai gave attacked. It was powerful though. More powerful them him alone. It had size too. Plus it was pretty quick. 

In the end Chewy transformed and wrestled it to the ground before clamping his teeth into the beast and holding it down with his powerful jaws into beast holding it in place long enough for Kai to strike the finishing blow. However, the end of the fight brought upon a new problem. About half of the place was destroyed. That was why Kai remained an extra few days to help fix things up. Sure Fairy Tail would get some bad publicity for the destruction, but it'd all get some good publicity... Or maybe just he would. 

"Welp... I've got some high quality meat for the guild so it shouldn't matter." The hunk of tail was rather large, but it was frozen solid. He needed to preserve it after all. The only reason he had it was because the people were so grateful. Especially after he actually stayed to help fix the place up a bit. Now he was almost at the guild. "Home sweet home." He smiled as he approached the doors. "YOOOOOO!" He greeted the guild out loud at he kicked the doors opened and entered the guild with a gleeful smile on his face. Chewy was awoken, but the sudden noise and movement, and let out a cute noise like a yawn before laying back down still a bit tired.
