Lucky bintang peminat-peminat . Miyuki Takara's Age

Knowing miyuki is still 14 and not as older like kona chan , kagamin , and tsukasa . and knowing that yu-chan is still older than her , is that even true ???? i saw it on the wikia when i was in the middle of searching for data in the wikia . i know it sounded impossible , but its not , she is a smart girl she can even jump classes , and seeing her that tall that even beats kagamin and tsukasa is well usual for someone younger to be taller than the older . can Miyuki Takara peminat-peminat and the hard core lucky bintang peminat-peminat have the answer?
