I have awakened my Yuyu too but she is still a good unit as she packs a bit more power than Belinda who is a plat unit and for a gold unit that is pretty good, though Yuyus other stats aren't as high as Belinda's. Plus she can be mincosted to 11, 10 when awakened where as Belinda can only go down to 12 but of course will be easier to min cost than yuyu.
