[ Sona ✩ Abilities ] Cry's abilities revolve around being supportive and escaping. In his guardian angel form, he is not allowed to unleashed attacks that may cause damage to innocent people. Sure, his abilities can be used for a workaround to cause damage, but never directly with the first intention to be causing damage. His main abilities are the ability to unlock and lock anything that has any short of locking mechanism, and his secondary ability is the ability to open space rifts/portal keyholes.
Keyholes: Cosmic portals opended using his weapon, the Keyharp. With it, Cry can open keyhole shaped portals which leads to anywhere he knows the location. He can open portals in unknow locations, but that would be extremely risky, and he cannot choose the unknow location if he doesn't know at least the coordinates.
Keyharp: His main weapon, a key shaped weapon, which is also a harp, as the name implies. The key side is used to open Keyholes as mentioned previously, while the harp side is used to summon, be summon small support creatures, or summon supporting abilities, like healing abilities, all in which requires a specific melody to be played to summon them.
