Sailor Moon Series 2 #75 - Twins? Mina & Serena!
Serena was in a state of shock because enemies had taken Darien from her. But her friends the Sailor Scouts did their best to cheer her up. Serenea felt better and realized it was her turn to be a hero. She said, “I will save Tuxeo Mask™!” Mina offered to help, too.
Serena and Mina are good friends, almost like twins.
