A/N: Honestly, it has been a long time since I have updated this oneshot series.I have been busy with my schoolwork and the fact that I am obssessed with Danny Phantom and Doctor Who right now.This is actually an old drabble of mine stuck on Facebook, based on a writing prompt. Still, this is KoroAgu. (I think I should have a separate oneshot series for them.)

Sense of Humor

Characters: Koro-sensei/The God of Death; Yukimura Aguri

The Reaper looked around the room, his mellow dark eyes roamed in every corners of the white fortress he was in, as he paced back and forth then towards the other side of the room. As he reached the glass wall separating the other side, his hand had met the cold glass. He can see a door in front of him, waiting for someone to get in and meet him.

Suddenly, the door opened and a dark haired petite woman came in, wearing the most ridiculous dress the Reaper have ever seen, covered under a white lab coat, and she was holding a clipboard in her left hand. Her sparkling dark eyes were shining with optimism, unlike the Reaper's cold and emotionless ones.

The Reaper chuckled as he looked at the newcomer, a smile gracing his angelic features, "Well, this is a nice change of scenery," he quipped with a joke, folding his arms as he then smirked, trying to ignore the newcomer's chest. The woman infront of him raised an eyebrow, as she was confused at what the man was saying.

The woman then put the clipboard on her desk and went to the Reaper, her right hand had touched the glass that separated them, as her dark orbs looked around the room, trying to find out what he was implying.

"It is a prison cell, Reaper-san," the woman said in confusion. The Reaper deadpanned upon hearing her confused words, realizing that the woman infront of him did not understand his joke. He wanted to facepalm at her confused state, definitely with a dress as ridiculous as a clown on a birthday party, the woman seems to have no sense of humor.

He rubbed the bridge of his nose as his weird eyebrow narrowed, a growing headache has started to set in, as she had wiped the smug look in his face, "I was being sarcastic, Yukimura-san."

Yukimura Aguri looked at the Reaper for a few moments, before she raised her one eyebrow then snorted loudly, making the master assassin looked at her in confusion, his once cold heart melted at the sight of Aguri laughing.

"Wait, what? Why am I feel weird when Yukimura-san laughs or smiles?"

The Reaper doesn't want to admit it, but he was starting to look forward to her visits and smiles she was flashing in his way.

Aguri stopped laughing as she smiled and knocked on the glass, whispering sweetly as far as the glass could allow to reach the other person's ear, "I know, Reaper-san, I was just messing with you."

The Reaper's comedic annoyed stare was all it take for Aguri to laugh so hard once again.
