A group of grade schoolers who combine their efforts to help those in need, although their smiles usually do the trick anyways (to their surprise, confusion, and sometimes disappointment).

Mimi of the middle class is always at the ready to help, sometimes charging in recklessly if she knows there's something she can do. Of course, she knows when to fall back if the going gets too tough, but now she believes she can do anything with the help of her friends. As a middle point of the two classes, Airy and Berry agree to have Mimi as the main leader (although leadership is interchangeable depending on the problem).

Airy of the high class prefers to stay tidy, and she has the skills to make her and those in her care squeaky clean, ready for any future confrontation. Being of a higher class also means she has knowledge of proper etiquette, which helps if the problem is attracting or convincing a love interest or authority figure.

Berry of the low class isn't afraid to get down and dirty if the situation demands someone to be as such. This sort of courage is much-needed when fetching lost items down in small, difficult-to-reach areas. As something of the trio's vanguard, the others usually have to pull her out when things get dicey.

And then, when all is done, it's time to finish up studies and go home for dinner.

So basically they're the Cutie Mark Crusaders, but as Pokemon.
