It's just occured to me how different Oshi no Ko's Aqua and Konosuba's Aqua are:
* OnK's Aqua: Is incredibly intelligent and knowledgable (was a doctor in his previous life). KS's Aqua: Is kind of dumb, being one of her lower skills
* OnK's: Is usually stoic and stone faced. KS's: Often gets emotional and sometimes breakdown
* Onk's: Doesn't care about his romantic life and if others find him attractive. KS's: Had a mental brakedown when Kazuma said he didn't find her sexually attractive
* OnK’s: Says that he isn’t kind and caring, but is deep down. KS’s: Claims that she is benevolent, but is often self-obsorbed
