since ai said that she's not ready to be leader yet and if miki does leave MM, i wish that instead of Ai and Risa being leader/subleader, hope they become co-leaders. which would be great....i think.
just imagine, during an interview, Ai was question and she is struggling to respond, then Risa comes in to save the day and Ai will just follow Risa lead. Ai's great, don't get me wrong, but as far as leadership abilities....Risa would probably best Ai.
