At least in the anime she's better than Rikka but nothing beats a chuuni with actual powers.
Rikka in chuuni Ren was annoying and childish, I wanted Satone to beat her and Yuuta to force Rikka to grow up. There was no development in that clusterfuck.
s2 made Rikka more like that faggot's daughter instead of his girlfriend. Instead of her chuuni tendencies alleviating after accepting her father's death they just stayed the same. You began rooting for Saotome because she has actual inner conflict between the chuuni cosplay and her inner mental workings proving that she's actually outgrown chuunifaggotry yet has been maintaining the facade due to the unrequited love for the Dark Flame Faggot who completely ditched his chuuniboi persona and ran away, he ran so far away.
She is just one of several of her class, only that her build is unsuitable any purpose but personal fulfillment. She may have powers, but so do a lot of adventurers, and that makes her relatively normal in comparison.
Chuuni characters in general overrate themselves and then get put in their place.
