Sitting at almost 14K Bond crystals. Aiming for one of the girls, since the cheaper D coins have not yet refilled.
Bying them with D coins ups the price in bond crystals around 25+% from a quick look ? But dont quote me on that.

Also I am still waiting for Nutaku to implement the damn bond crystal system. Had to increase my capacity to 750 and with all the 3* I`ve been getting in the last two events I had to start selling them in batches to make room for other stuff.
