A 10-year-old girl lives in Shuang Ye Town, where the immortals live. Traveling with the goal of becoming a coordination trainer is one of the companions who travel with Xiao Zhi in this work. Her goal is to become a top coordination trainer, just like her mother johanna. Her beginner Poké mon won the Piplup from Yamanashi College. Interestingly, this Piplup has the same personality as her. She likes to say "no problem" and "it doesn't matter" most, but it happens that she often says this sentence with the most questions.

With the goal of becoming a top coordination trainer, Xiaoguang took part in gorgeous competitions all over the country, collected all five ribbons one by one, and finally appeared in his dream grand celebration. After this department ended, I decided to continue my trip to Fengyuan.

Her Poké mon was either released into the wild or put in foster care at the institute or at home. The two-tailed monster hand and Buizel are more of Poké mon's own choices.
