Over the past 3 days, Jellyfish has introduced us to all 9 members of the label's soon-to-debut girl group, including current IOI members Kim Se Jung and Mina, former 'Produce 101' contestant Nayoung, as well as members Mimi, Hana, Soyee, Haebin, Sally, and Hyeyeon! 

Pretty soon, we'll get to see these girls get together for a remarkable debut! Stay tuned for more on gx9!
