(Sorry for the long intro)

The last thing he remembered was falling down into the infinity castle with the hashira and his friends. The last place he'd expect to find himself in was a pleasant looking park on a bench. He looked around, clearly confused for obvious reasons. How did the infinity castle send him somewhere like this. Where was Tanjiro? Where was Nezuko? And where was his brother!?

“Hey, Read the sign no loitering!”

He looked up at the sound of an unfamiliar voice, his eyes clouded in a daze. above him was a man dressed in some strange uniform, a police officer?

“Oh.. U-Uhm sorry sir.” He replied shakily, looking around. Still very confused and very disoriented. He scratched his chin. “Where... Am I?” He asked again. The officer's face scrunched up. The man was clearly contemplating if Genya was on something. “You're in Tokyo you idiot, besides what are you even wearing! You look young, you should be in school! ” The man screamed at him. Genya stumbled up. Confusion clear on his face. The officer grabbed him by the hand and dragged him to the police car. Tossing him a school uniform and driving him to the nearby school. While Genya was getting dressed in the strange unfamiliar school uniform while the officer was talking with the principal and head master.

Genya was completely confused. Where the hell was he. This wasn't the Tokyo he remembered. What were the strange clothes everyone was wearing, what were the strange forms of transport and everything just looked so different.

When he was dressed one of the teachers lead him to the classroom. He was seated at the desk next to the window that was right next to you. He looked at you as you studied. And tried to understand what the teacher was saying. All he could think about was finding his friends and Sanemi.

“H-Hey... I'm Genya.” He awkwardly introduced himself.
