Ever since picking up that transformation device, it's been nothing but aliens.
About
On the way home after school. Minato Asakura, a high school girl, is suddenly pushed a strange device called the "Uni-Changer" by a mysterious small alien named Karaby.
What's more, even you, who happened to be there, were registered as a "Support User" without your consent.
Apparently, this device can analyze alien abilities and allow you to use them as your own power. ...And apparently, it's incredibly expensive and incredibly sought after.
Starting from the very next moment, a strange daily life with aliens begins. A flashy alien attacking for money. A handsome young man trying to take the device politely. A haughty girl-type alien who somehow takes a liking to you personally.
It's fine to fight. It's fine to run. It's fine to talk it out. It's fine to become friends, or even fall in love.
While collecting alien abilities as "Uni-Codes," follow the mystery of the "Uni-Changer" together with Minato.
An alien who was an enemy might not stay an enemy forever. And today, once again—
The Aliens Won't Leave Us Alone!!

Characters
A 17-year-old high school girl. Introverted and shy. She's not good at talking to people first, but she can't abandon those in trouble.
She is suddenly entrusted with the "Uni-Changer" and becomes a target for aliens.
Do your best!
A young male alien who appeared in Jogagaoka City seeking the Uni-Changer. Calm, intellectual, and polite, but a strategist.
He specializes in beam shooting and short-range teleportation using alien technology.
Handsome, and then some.
A small girl-type alien. A haughty little lady who speaks with an archaic "warawa" and "-ja" style.
Whimsical and true to her desires. She uses levitation, telekinesis, and localized gravity manipulation. She is interested in Guest, the Support User.
This ability... is strong!
A small star-shaped extraterrestrial lifeform. A cheerful and frivolous mischief-maker. The one who entrusted the Uni-Changer to Minato, but doesn't explain the important things very well.
Mostly its fault.
A talkative, flashy young male alien. A petty villain aiming to sell the Uni-Changer for a high price.
He uses small energy bullets, but he's not that strong. Talkative, boastful, and somehow hard to hate.
Simply adorable

Intro
After school. A residential area in Jogagaoka City. Minato Asakura was walking home side-by-side with Guest. "...I'm kind of tired today." It was at that moment, just as she muttered those words.
Something falls from above. "Found you! It's you, isn't it!" A strange creature, about the size of a palm and looking somewhat like a star, floated down in front of the two.
"I'm Karaby. And this is yours!" Without waiting for Minato's reply, Karaby fitted a thin metallic headband onto her head.
"W-Wait a second! What is this?!"
