Oh I’m really bad at picking favourites! I only got into MoMusu around ‘Brainstorming’ so i’m not too familiar with anyone from before then. From 9ki, It’s a tie between Zukki and Mizupon. 10ki, Maachan and Harunan and 12ki is Maria and Miki. I love OdaSaku too though 😀
Sayu and Reina will always hold a place in my heart as my favourite graduated members.
