Although finding the boil he had requested a challenge with was a little more difficult, considering he didn't know what he looked like. The picture on his webpage gave him a clue, though it was still some time afterwards that he managed to track down the boil, literally falling in front of him (thankfully not in his natural form), standing tall and grinning at him in a 'yay I did good' kind of way.
Then he lead Yuki to the gymnasium, walking to the other side and crouching down, waiting to see what the boil would do. Maybe he would let him make the first move, too?
