While MK was being chased by Red Son throughout the city, Mei rescues MK and takes him to Pigsy's Noodles, where she learns that Red Son was actually trying to kill MK instead of playing tag. When Pigsy gets mad at MK due to a customer giving Pigsy's Noodles a zero-star review, Mei takes it as a compliment until MK goes inside the noodle shop to speak with Tang.
When MK told Mei, Pigsy, and Tang that he found the Golden Staff, Mei and the others thought he was being delusional until he uses the staff again.
At the Sea-Crate HQ, Mei and Sandy were inside discussing if they even need a headquarters until MK comes in to tell Mei and Sandy that Pigsy is missing. When Mei checks the camera she installed in Tang, MK realises that Tang is also missing and the others then notice that Pigsy and Tang were kidnapped by the Spider Queen.
Later, Mei and the others ventured across the Silken Web Cave by using Sandy's Speedboat to rescue Pigsy and Tang, but only for them to get ambushed by the Spider Queen. However, when Mei dropped the Dragon Blade when she was caught, Pigsy and Tang were able to use the blade to free themselves and the others to rescue MK, who was being chased by the Spider Queen.
After MK's Team confronted the Spider Queen, Mei and the others attempt to rescue MK but only for the Spider Queen to attack MK again, but only for her to cause a giant hole, causing Mei and the others to fall down until Sandy rescued them by using his Speedboat and escaping.
At Pigsy's Noodles, Mei was on her phone until MK runs in after being freed from the Calabash. However, when MK said that he's glad that Mei, Pigsy, and Tang aren't perfect, Mei and the others get mad at MK and remarked that they are perfect.
After MK received the key, he and Mei used it to go to several places in the city and have fun until pulled a prank on Pigsy by using the key. However, Red Son steals the key from MK and escapes by using his Inferno Truck. Although, Mei uses the White Dragon Horse Bike to go after Red Son.
Eventually, Red Son was able to outrun Mei until MK used the Golden Staff to stop Red Son and get the key back. However, Princess Iron Fan arrives and engages in a brief fight with Mei and MK until Red Son gets the key back.
Mei is overall a nice, cheerful girl who loves races, playing video games and hanging out with MK and his acquaintances. She can also be a bit of an air head since she thinks Pigsy's noodle shop getting a bad review is better than no reviews at all. She is also very protective of her friends since she became filled with murderous rage when she believed MK was killed by Princess Iron Fan and wanted to kill the Demon Bull Family.
Mei is a young girl, presumably a teenager. She has short chin-length hair with part of it tied in two small pigtails and two strands dyed green.
