Is this arcade game corner the kindest or cruelest for idol otaku who love game for little girls?

The Aikatsu! arcade game was primarily designed for little girls, who can use separately purchased cards to dress up the on-screen characters in brightly colored, frilly outfits and watch them perform various song and dance routines.

So should the owners of the machines welcome the Aikatsu Oji-san with open arms, or try to drive them away?

A prime example is Aikatsu!, the excitedly titled series about junior and senior high school students trying to become idol singers.
