I was thinking of giving Hamachan her own thread. Does anyone remember her "title" for Hinafest?
Hama-chan (はまちゃん): Official nickname, given to her since joining Hello Pro Kenshuusei.
Taisa (大佐; Colonel): Used by fans. When Hamaura gave instructions to members for the Hello! Project Hina Fest 2015 ~Mankai! The Girls' Festival~ lottery, she marched into the room wearing an army cap and called herself "Hama-chan Taisa" (はまちゃん大佐; Colonel Hama-chan).[5] She returned to the role for the 2016 lottery.[6]
