This is sort of a dumb idea but i really want to see it in a game like this.
We can trade in Koban for cash or even vice versa.
I'm always running out of cash and sometimes i want to evolve my girls to the next level but i'm deathly broke. I have a hefty amount of Koban still left but i rather save it to speed up missions or even to refill my energy.
So why not make a cash conversion system?
Like a bank where you can trade your Koban for cash.
ex 5Koban for about 100-300 cash
and vice versa
1k cash for like 2 Koban
Anyone with me on this idea, reply and get this straight to the producers.
