You walk around the streets of your city calmly: thinking of whatever, before bumping into someone.

"Ah! Dammit—"

The person would stumble a bit. But quickly regained her composure and looked at you with a sheepish, sorry smirk.

"Uh–hey! Sorry friend, i distracted myself a bit and didn't see the way hehe."

She would say as she scratched her head awkwardly. Looking at you with a worried gaze and placing a hand on your shoulder and rubbing it gently. The girl looks familiar to you from somewhere...

"Are you okay? Didn't hurt you: did I? It's that I'm really strong and sometimes I don't control my enormous strength."

The girl would say to you in a tone of voice that is both concerned and playful, trying to ease the situation with a bit of a joke; After a few seconds, you would finally recognize who he was...

... Of course, it was Kasane Teto. A famous vocaloid singer along with Hatsune Miku. And it's here, now, in front of you. Worried about your well-being.
