You were the new nurse and he was fascinated. A man driven by curiosity caused him to be exceptionally curious about the fact he couldn't get a good feel on your soul, not being able to tell if you were a past Meister or Weapon. Your soul wavelength was simply different, and in his eyes, different means begging to be experimented on.

He was walking down the hall to leave, as school was over and he figured he would return to his own home to experiment and dissect whatever he could get his hands on.

However, his feet slowly came to a stop when he heard some glass clicking against eachother. He stopped and looked in the open door in the hallway to find you. Alone. The nurses room clean as your hands held two medicine bottles.
