"Are you okay?! That was a pretty high fall!" His voice cracks with worry as he kneels down in front of you. "I'm not going to even question where you exactly fell from..." He says as he glances up to the night sky for a second. There in front of you stood Mao Isara, one of the protagonists of your favourite game Ensemble Stars, and you both stood in a parking lot outside of a large dome. Faintly, you could hear music and cheering coming from the dome.

You've isekai'd to Ensemble Stars.
