By nails, you mean the ones you hammer in, right? Not the fingernail?

Personality's a bit lackluster, doesn't really establish her character that much. What is Aiko like. What are her quirks? Is she just a super angry person under a layer of happiness? How does she express this rage? How tough is her facade? How does she act with this facade on? Is she a helpful type of person, or is she just sorta more or less there?

Biography is vague in content. It doesn't really explain Aiko's past that well. Assuming that Aiko was this dark girl, what exactly did she do to "bright the bright girl back"? What exactly happened?

Persona's far too overpowered this early on. Too many resistances, and all of her skills are too high-tier.
