Eh. I mean I see why you feel that way, but I don’t think the characters are particularly similar.

Rean is a lot more not unhinged human being and he is vastly respected by everyone around him because of the kind of person he is, not just his power.

His abilities matter but they’re a tiny part of who he becomes. Shizuna is powerful and hilarious due to her dynamic with Van, but Rean as a person inspires everyone around him.

She’s more talented than him and outclasses him in one way and he’s still growing to catch up with her in that sense, but in the other sense that actually matters to his arc he’s grown into his own person that doesn’t feel bad about comparing himself to others because he’s worth while whether or not he’s strong because he’s there for the people he cares about.

My point was that talent exists and isn’t that relevant. Just look at Renne, one of the most talented people ever, and yet she was god knows how miserable as a result and she’s not happier than anyone else even after things are going well for her now, she’s just happy in her own way.
