The Past
This takes place several years before MK is born. Focuses on Fang returning to Megapolis to deal with a problem, as well as eventually facing her father after 10 years of silence between each other.
Return to the City
It has been 20 years since Fang left home. And 10 years since they last spoke with their father Wukong. Both having exchanged heated words with one another in regards to Fang's safety of traveling on her own, until Wukong conceded and let her be.
Now they wander the roads in the near West. Having teamed up with their friend Jun. And upon their adventure, they run into a strange but not uncommon scene of a demon being hunted by hunters.
Taking quick action they easily defeat the group, saving the fellow, who introduces himself to the two as Amsel Zephyr, a foreigner from the far West who is on a mission to assess the migration patterns of a particular species of moth's. Given that it is rather late at night, and this stranger is a Demon, Fang and Jun argue about what to do, until finally coming to the decision to help him. However, Fang offers their aid to them on the condition that they speak not a word of their encounter to anyone before summoning a nimbus cloud before them. Amsel Zephyr or 'Moth' for short, is startled with the revelation that they stand before a 'Celestial Being', for who else can summon golden clouds so easily? Though they know not of the Monkey King as much as most other demons, they know enough of the relevance in certain magic's to know who to be wary of.
But at that point it becomes too late to back out now, and they load him up and proceed to fly to the nearby grove where he requested they land. Upon closer inspection there's hardly any moth's in the area, specifically Lunar Moth's. A rare and often unseen species that frequents the area due to the magical properties of the magic gemstones embedded into the grounds of the grove which enhance the magical properties of the moon, granting them longer life through their travels. Apparently a few have been stolen and after finding an older moth unable to carry on with the others, they find out where. Megapolis.
Fang is against visiting wholeheartedly, but given that the situation in the city is unreadable given their current position (i.e no signal) they decide to escort Moth there to help scope out the situation and promptly deal with it.
What they weren't expecting however was a full on infestation swarming the city all around.
