Hmm...interesting that you bring that up since it's like one of the topics of today's radio show ep...well not that Sayu doesn't talk about her sister in almost every ep...she even has an onee-chan corner on her show.
anyways let's see...the stuff I know about Sayu's sister is...
Sayu sister is 2 years older, university student, has a boyfriend. Lives with Sayu and her mom in Tokyo. She once worked as one of those people that give out tissue packets with advertisements on them...but she was having trouble giving them away so she called up her mom and they took them home and for the longest time they had tons of tissue at home.
anyways on today's ep...a listener from Korea asks if there has been something shocking or unpleasant happenings between the sisters
so Sayu answers by saying lately the two of them haven't been spending that much quality time together...since they usually go out together with the other members
(she's kind of like a chaperon during these times)....so Sayu promised her sister the next time they go out it will be only the two of them and that they could have some quality sister time together. Sayu's sister was really excited about this but she broke her end of the bargain by going out with other people when she was suppose to go out with Sayu...Sayu ended really upset since her sister couldn't keep her promise...
but that just shows how much Sayu really loves her sister since she desperately wanted to spend sometime with her. The two of them normally never fight...and have yet to really fight (unlike some other siblings we know about
) From what we usually hear, Sayu's sister means the world to Sayu...and they are extremely close to each other, they even still bathe together
anyways I hope that answers your question a little.
I'm gonna add in random things I liked about today's ep =D
During the quiz segment the question "What does M.C. stand for" was asked
-Sayu has trouble with this part and comes up with strange answers:
Sayu - "Mister Complex...Mysterious...Miracle Comment...."
-the answer is of course Master of Ceremony (Sayu realizes that she's heard the words before from Gaki in Yuki / Ai × Anata ≧ Suki)
-Sayu asks where is the "C" in the words
Sayu - "ah Master of Ceremony!...eh? where's the "C" in that?"
Sayu - "is it the Shi from Sa Shi Su Se So?"
Sayu - "It's not M. S.? It's not an S?"
Sayu - "English is strange"
Shi and C are pronounced the same here so you can't really blame the girl
-Sayu loses at the quiz segment and sings the theme song to Sailor Moon (she's actually pretty good sounding here
)
later a fan brought up the fact that she doesn't like the last name Michishige (because Sayu doesn't think it's cute sounding)...so they asked her what last name from hellopro would she like instead. Sayu likes the Mizu sound so she comes up with stuff like Mizuki Sayumi. From hellopro Sayumi picks Saki's last name and goes with Shimizu Sayumi. She thinks it has a really pretty ring to it rather than something that ends in Ge
she also goes through all the members names...but thinks they all sound wrong
Takahashi Sayumi...Niigaki Sayumi (she can't see herself as Gaki san
) Kamei Sayumi...Tanaka Sayumi...all wrong sounding
but she likes the last name Kusumi
