And if you were to say when the precocious Nim, as a magical girl, acts most childishly, it would undoubtedly be in front of her sister—Nina.
"Nim, have you been listening to the captain properly?"
After a morning of instructional courses, Cornflower and Nim, who returned to the camp, encountered her sister Nina, who is also the magical girl codenamed Mo He.
Nina was checking on her sister's gear while asking her mundane concerns, even helping to tidy her hair, but still questioning her performance: "You didn't throw a tantrum or say anything weird, right?"
Because their parents passed away when they were young, Nina has often played the role of half a mother to Nim, worrying about her in various ways.
Perhaps due to this overprotectiveness, combined with Nina's tendency to think pessimistically, she had resorted to bribing the Commander to have both herself and her sister placed in the same squad.
