Classless in a Game-Like World: I Have Infinite Skills in My Library

[Awakening Class... Awakening Failed! The user will be classless] [Awakening Unique Skill... Awakening Successful! You have obtained the skill: Akashic Records — EX Rank] Akashic Records — EX This skill allows the user to access a library where records of all skills that have existed and will exist are stored. The user can take a card with the chosen skill and absorb it. They can use it without any cost of [Spiritual Energy], in exchange each skill will have a determined cooldown. Each skill will occupy a skill slot until the cooldown has finished. [Error!] [Warning ⚠️: the user's skill is too dangerous — the Spiritual Realm is limiting your power] [Limit: You will only be able to access F rank skills — evolve your spiritual core to break this restriction] ____ One cannot survive in the Spiritual Realm without a class, it's common sense. Without a class you don't get skills, and without skills you can't kill monsters, which makes you a failed player. However, Sora Sieghart broke that law. He awakened a unique skill while completely lacking a class, something that had never happened before. Despised by everyone for being the son of a traitor, Sora must survive in the spiritual realm using only his unique skill to become more powerful, while hiding his identity from the world. The Spiritual Realm is not just another dimension that must be controlled to prevent monsters from escaping into the world, but also a show that is broadcast 24/7 throughout the world. Sora will have to bear the pressure of being watched while trying to clear his father's name and save his sick sister. But thanks to his ridiculously powerful skill, it won't be that difficult for him.
