Victory Cry is an ability that is a passive one. This means that it activates on its own without you needing to think about it. Victory Cry will fully restore (in most games) the user’s HP and SP after each battle. This is an excellent ability that ensures that you go into every battle at full strength. While it sounds great, you can go the entire game without earning Victory Cry. In some games, like Persona 4, it is possible to get it as a skill card. In other games, such as Persona 5, you can only get it through leveling up. Izanagi-no-Okami, its Picaro variant, and Satanael are the only options. From there, though, you can gift that skill to another Persona by using one of those three as fusion material. This can effectively allow you to share the skill with any Persona you want but it will take a lot of fusion.
