"Mankai" and "shichibuzaki" are terms used to describe the stages of cherry blossom blooms: "Full bloom" and "70 percent bloom", respectively. Rendering that in English without sounding horribly awkward isn't very easy, though. Myon describes Yuyuko's face here as a 70% cherry blossom bloom that has never known a full bloom.

The terms sounds like Yuyuko's last spellcard in PCB.
