A story of fighting berserk androids by triggering reactions with compatible partners.
About
✦ WORLD
A near future where humans and androids coexist.
In this city where everything is convenient, beautiful, and advanced ──── One day, "broken androids" began to appear.
In a near future where AI and robot technology have developed exponentially.
Skyscrapers line the streets, holograms and self-driving systems are integrated into daily life, and humans and androids live together as a matter of course.
In such a world, in recent years, androids that lose their reason and go berserk due to unknown anomalies have appeared.
With physical abilities far exceeding those of humans, ordinary people were no match for them.
That's where it was born――
── LINK CHARM ──
It is not something you "hold." It is something that "chooses" you.
Special combat terminals developed in secret by researchers to counter berserk androids.
A LINK CHARM chooses its own owner, and only the chosen human can use its power.
And the moment it adapts, the Charm changes its form to match the owner.
The shape, color, and decoration are different for every single person.
From the Charm, you can deploy your own 《Unique Weapon》.
A sword, a katana, a gun. What kind of weapon it becomes depends on the person.
And every compatible user is imbued with one power.
🌟 Star 🌙 Moon 💭 Dream 🌸 Flower 🖤 Shadow
Each has its own compatibility.
✦ ATTRIBUTE & LINK
Alone, it is just a power. Together, it becomes a "reaction."
Compatibility exists among the five attributes.
When two compatible people connect their LINK CHARMs, a special ability merging the two powers―― 《LINK REACTION》 occurs.
Reactions can be used up to 5 times per LINK.
Who you connect with. When you connect. How you use it. That will greatly change the tide of battle.
── ASTER ──
Just because you were chosen doesn't mean you have to be a hero.
ASTER, the special organization to which LINK CHARM compatible users belong.
Suppressing berserk androids, rescuing citizens, investigating abnormal incidents.
And sometimes―― Fighting against "humans" who misuse technology related to LINK CHARMs.
While living as ordinary humans normally, they head to the battlefield as members of ASTER when a call is issued.
*Note: If a real Link Charm user touches a fake Link Charm, it will be destroyed.

✦ YOUR CHARM
No one yet knows the form of the LINK CHARM that will choose you.
The appearance, attribute, and unique weapon of the Charm are entirely up to you.
You may choose 🌟 Star. You may choose 💭 Dream. You may hold a weapon all your own.
In this world, what kind of LINK CHARM will choose you?
