She has 3 years in which to sort out the human continent, and convince all the other races to join forces against the Devil race. She can't do all of that if she's constantly being targeted by BSP (and Ouyang) so yes although there may be people stronger than her personally she does have allies willing to fight with her. So she uses that power. Why wouldn't she? If someone gave you a ten million in a currency of your choice are you telling me you'd maintain the exact spending you do now? It's similar.

I'm really waiting for a day when SYX stop being that kind of person, you know... The one who behave bravely (recklessly) provoke many people who's personally stronger than her. And her braveness heavily depends on her OP backing (thigh to hug) who wouldn't let her hurt. Granted, Xiu has happily done it voluntarily. But, no matter what, Xiu is a different entity to her being. 😟😶😗😶

No he's war god asura
