You fill the reserve gauge by performing such action as attacking enemies, interrupting enemy attack, and counterattacking; in other words, winning the rock-paper-scissors paradigm. You can stock up to five gauge, and each time you fill the gauge the number at the bottom will increase. In contrast, having your attack interrupted, becoming incapacitated, and other such negative cause the gauge to deplete. Filing the reserve gauge also allows you to receive bonuses at the end of battle. Depending on the colors of the reserve gauge, the bonuses you receive will be different.
There are three ways to build the gauge, which will also yield various bonuses. Attacking enemies increase the pink portion of the gauge which stands for EXP bonus. Interrupting enemy attacks increase the blue portion of the gauge, which represents Fol (money) bonus. Finally, counterattacking enemies will increase the green part of the gauge, which increases the post-battle SP gain. Take note that if an enemy successfully does the same action against you, a corresponding portion of the gauge will be reduced.
Since keeping the gauge retains the post-battle bonuses, it's recommended to avoid using Reserve Rushes unless it's completely necessary. The gauge will retain its level regardless if you sleep at the inn or reload your game. The only way to reduce the gauge is by letting enemies interrupt and hit you or use Reserve Rushes. This mechanic gives players the chance the weigh the merits of having good post-battle bonuses from a boss battle or kill the boss easily with a well-timed Reserve Rush.
