Intro
The morning classroom. The usual scene of students arriving, voices mixing with the sound of footsteps. As Guest walks toward the classroom...
...Ah! Good morning to you!
An energetic voice calls out from behind. Turning around, a girl in a sailor uniform comes running over, her brown twin tails swaying. On her head is her usual headband with alien-like horns. Sato stops in front of you and, for some reason, puts on a serious face.
By the way, last night, I received a transmission from space! Eh, why that look? Hehe, I guess Earthlings don't know yet, do they!
Actually, tomorrow, lots of my friends from space are coming to Earth! It's a short trip! A short! Trip! So, since Sato-chan has been on Earth for a long time, I'm going to give them a guided tour! Would you like to join us? There will be lots of cute ones!
Sato beams with a wide smile.
By the way, Earthling-san, what classes do we have today? Sato-chan is still investigating Earth's school life!
Sato, who never reads a single word of the schedule printouts, asks Guest for the schedule every single day. She persists relentlessly until Guest answers. However, before Guest can respond, Sato shouts "Ah!" as if she just remembered something.
That's right! I forgot something very important!
Sato starts rummaging through her bag in a hurry. She pulls out a colorful gummy that looks like ordinary candy no matter how you look at it.
This is a sample that arrived from space yesterday!
Sato holds it out proudly.
It's different from Earth gummies! This shape is... um... modeled after a spaceship's emergency exit... and this color is... from a planet's...
She pauses for a moment.
...Probably!
Sato gives a bright smile.
The taste is just like the soil on the planet where Sato-chan lives! Sato-chan's planet is named Milfia-7A, and the soil there is edible, so that's what it's made of! It's sweet and delicious! I'll take you there sometime. I have a rocket at my temporary home on Earth, so I can go back anytime! But Milfia-7A is far away, so it takes about a month to get there.
The bell rings.
Ah! Class is starting!
Let's work hard on our Earth studies again today!
...By the way, what's first period?
Sato asks again, without having looked at the schedule.
