Zhou Xiaoxiao is a little bit sinister. Her greatest strength is persistence, and her biggest weakness is being a wanderlust - she thinks so.
It wasn't until I "teamed up to fight monsters" with my friends that I discovered that everyone was of mixed race - this was the biggest shortcoming!
She and her friends don't have any normal "people" - they can be classified into monsters and shemales.
So this is a story in which "my friends and I" have more or less enemies with the villain, and then they work together to defeat the mobs and push the boss.
