Dropped in after reading Risa Yoshiki's effusive endorsement of Rena's PB (Kingyo). I'm a little surprised the interview I read didn't comment on their shared birthdays!
Gotta admit that, as lovely as Rena is, I'm more impressed with the dedication of the posters in this thread! Terrific. I doubt I'll become a massive Rena fan, but I am such a fan of the posting here that I might still go back and start at the beginning!
