Mai features exclusively in Cream Lemon Part 4: Pop Chaser as a waitress at the Sailor Uniform Saloon. This frontier-town establishment functions as both a bar and hotel, employing only waitresses in sailor-style uniforms. When Zack’s bandit gang harasses the town, Mai approaches Rio—a motorcycle-riding bounty hunter lodging at the saloon—to seek her help against the gang. Mai thanks Rio for accepting. Later, Zack’s gang kidnaps Mai and the other waitresses, prompting Rio to rescue them.
