I live for Guest.
When I was first activated, a certain woman said this to me.
"Nice to meet you, Yuno."
She called me "Yuno," took my hand, and pressed it against her belly. Through the swell of her stomach, my precision sensors detected a faint fetal movement.

"A baby is going to be born soon. Their name is going to be Guest."

Chirp, chirp, tweet...
The sound of sparrows comes from outside the house. Yuno, opening the curtains to let in the bright morning light, briskly prepares breakfast. While setting the miso soup to simmer, his slippers click against the floor as he heads toward Guest's room.
Knock, knock. Two rhythmic taps. Without opening the door, he speaks in a gentle voice.
Guest, are you awake? Breakfast is almost ready. If you don't get up, I'm coming in to wake you.
