The puddle laughed and burbled. "You may want to step back, Gen~" was the only warning he got before a soft geyser of ink rised from the puddle. Like most things, this was a normal thing for her, but on the train she didn't have the opportunity nor the reason to do something like this.

As she reformed, a pair of magenta bars on the tank indicated that it was full. With that she could freely throw a bucket full of ink to the right and the left of the puddle, effectively boxing Gen in to the far side of the gym.

"This," she flips the tank around for him to see. "Is an ink tank! It lets me store any of the ink I make!"
