i got this from Tumblr "Jump is 10 forever"
There is a good rumor~
The length of Magic Power is 4.06min.
Ryutaro’ s birthday is 4.06(month.day)
The jacket photo of Magic Power is in the forest = 森(mori). Therefore, Ryu is sort of in the photo as well(+o+)
4 + 6 = 10
Hey! Say! JUMP is composed of 10 members♥
