So now that Sayu is the member with the longest MM history, I think she will graduate after the second single with 12th gen. once its announced.
Like 9th gen. first single was Maji desu ka ska!, then Only You, and Ai-chan graduated after their third single (Kono Chikyuu~)
Then 10th gen. first…
Michishige Sayumi is now the longest active member in the history of Morning Musume.
Aibon, do you wanna eat Gocchin?
