Mukuro walked in the office with a smirk on his face.

Looking up from the paper he was reading, Tsuna raised an eyebrow at his mist. "And what are you doing here, Mukuro?"

"I love it when someone insults me. That means I don't have to be nice anymore." Mukuro stated happily.

Tsuna only gave Mukuro a questioning look. "Since when have you been nice?"

"Since today," he replied before disappearing.

Tsuna just shook his head, already used to his mist's weird personality and ways, and continued his work.

At that moment, a familiar scream could be heard, followed by a few explosions and a disturbingly loud laughter.

Groaning, Tsuna put his pen down and took a deep breath.

"MUKURO!!!"
