Like in AKB48, regular auditions to recruit new members are held, and the future successful candidates, the Trainee members, take part of a in-training team of members that work as sub and under for the official members in various activities (mostly the theater performances). And then, when any of the official members graduate, a girl is promoted to fill the space.
- Bolded names indicate members, which are still active in MNL48 or one of the sister groups.
- Italicized names indicate members with pending graduations
- The members' pictures are of members who are still active and are listed in accordance to the alphabetical order of members in each generation.
- Announced in April 28, 2018.
