How eccentric argument.
A kohai (which does not even know xD) asks a favor to her that will eventually allow she to earn € 2,000 in a week... while her girlfriend secretly triumphs as gravure. Yep, super believable everything. xD
I have my doubts about what really they do in her works to achieve such amounts xD
And the happiest, the owner of the rings store. xD
One is an esper who managed to teleport them to some far away place. If you have the power to destroy your atoms, send them to some light-year distance planet, and reassemble it again, then chances are you also have the power to modify your body in any way you want.
The other girl is probably rich and famous already as her brother is a famous musician.
Not realistic but it can happen in their universe.
