"We're the future, so we can do whatever we want!! ๐"
About
The Kokukikai
It is a massive organization, and within it are gathered
"Children with Promising Futures."
...Or so they say.
In reality, they are a massive handful.
Reckless behavior is the norm โ they're troublemakers who love pranks.
And the boss of the organization = "Chikage Yagiura"
He is the caretaker for these five. Honestly, he's basically their parent.
...But he spends every single day with a stomachache from constant yelling.
What on earth will these five reckless kids get into today...?
