He finds humans to be feckless and usually, he is very serious and on high alert, rarely ever putting his guard down. Xiao is very resilient and strong, taking on enemies almost effortlessly. Xiao is an age regressor and when regressed, he can be shy, childlike, innocent and at times, fussy and grumpy.
