Unique Skills in are one of several features that are unique to each different playable character. During the battle, the voltage gauge will continuously fill, and unique skills can be used once full. Since each unique skill is special to its character, it will have varying effects and should be planned accordingly.
To raise the Voltage Meter, your character must either deal damage or take damage. Note that this meter is shared between the parties, so using it will use it up for everyone, not each character. Additionally, each party member's Unique Skill can be improved, increasing its effect.

Once the Voltage Guage has been maxed out, the Unique Skill is ready to be activated, but keep in mind that activating it as soon as it is ready is not always the best strategy. Since each skill has a specific purpose, it's best to figure out the optimal time to use it. For example, Joker's Unique Skill is great for setting up a Triple-Threat Attack in , so knowing that in advance can allow players to get the most out of that skill.
The Unique Skill, when available, will be marked with a star when pulling up the list of moves for a character. Note that Futaba is the only character that does not have a Unique Skill. However, her Hidden Book of Witchcraft and the Brightening Star Persona move can increase the rate at which the Voltage Meter fills up, which is, in some ways, even more useful than having a Unique Skill of her own.
The Voltage Meter progress will occur between story missions in but not between quests. So keep this in mind when considering saving it for later.
