First encounter with Suzuka: I admit, it was when she was in Shinkenger. At first I was mixed up and thought that she was an AKB girl.
My favorite thing(s) about Suzuka:There's something really soothing about the way she smiles. If she smiles while looking right at you...it's just mo~eeeeeeeeeeeeeeeeeeeeeeee.
A memorable performance:I've been more of a fan of hers from her TV/movie appearances, so while I'm sure she does a good job at it, I haven't really seen many of her singing/idol performances.
Moment(s) that made me laugh:The "you don't mess with Suuchan" video. Funny/cute and awesome at the same time.

Also her "octopus girl" role in the
Mutant Girl movie, as well as the
Yoshie Zero extra vid that came with the DVD release.
Moment(s) that surprised me:Can I say "realizing that she was already 18" and thus "legal" without sounding like a pedo?
Favorite solo line in a song:Honestly, I don't follow Idoling!!! enough to know when Suuchan gets any solo lines.
Something I would say to her at a handshake event:I'd probably ask her something stupid like "Were there ever any plans to have Kotoha (her character from Shinkenger) have a crush on Takeru/tono-sama?"
A picture that I like:I still like it better when she's got longer hair, but it's hard to not like this one. Sure she's obviously wearing a bikini in the pic (even if we just see the top half), it's not overtly trying to be erotic/sexy. It's a classy/tasteful picture.
A video that I like: Episode 6 of Shinkenger (the one with the bad-mouthing Ayakashi). For anyone that doesn't know the show, it's an episode that established the inferiority complex (and I think, subsequently, the quiet inner strength) that Suuchan's character had.
