While mistakenly believed to be evil and an underling of his uncle, he prefers warping timelines to help others instead of causing meaningless destruction through his alterations, and isn't interested in revenge/reviving the Demon Realm. Fu dosen't like to fight but instead loves science and the possibilities his changes in history can create, taking after his mother in a positive sense. Fu's interest goes so far to experimenting on scenarios, fight mechanics, create time paradoxes to gain power
