Maa-Duu began during the auditions for Morning Musume. Masaki-kins went around the room and asked the other applicants their names and where they were from. She encountered Kudo Haruka for the first time and asked her, “What’s your name?”
“KUDO HARUKA,” came the blunt reply.
Taken aback, Masaki continued, “Oh. Where are you from?”
“HELLO PRO EGGS,” Kudo said.
Masaki, thinking maybe Kudo hadn’t exactly understood the question asked, with a bit more timidity, “Where is that?”
From that, Masaki-kins concluded that Kudo was probably a bit of a weirdo (reference).
Later on, she was happy to discover that this weirdo had also made it into the group. During their subsequent encounters, Kudo was bossy and blunt, but she was someone that Masaki really liked.
And thus a friendship, odd and cantankerous, was born.
After years of antics, possessiveness, and tsundere-pimpin’, Kudo graduated and Masaki-kins wrote a troubling blog post about it. And the speculation began. In my case, the first time I read a translation of Masaki’s blog post, I remember thinking, “Oh man, I hope she doesn’t quit.”
