These 3 girls may get in MM.

Koharu Kusumi is now 14 yrs old....Tsunku may consider these girls who are younger than Koharu....
also for the "senior" member who will graduate in the future (dunno who will)....
e.g. 8 girls --> 7 girls....then add 3 new members --> 10 girls.....to even the number....joking...
