Is that image of Umi making you think of a different particular character? If so, then I'm not quite seeing that. But am I seeing "magical girl outfit" here? Definitely.
A large chunk of the Love Live! costumes are indistinguishable from magical girl costumes. I'm not sure the exact percentage, but it's at least 10% and it might be as high as 35%. In the anime itself, the Season 2 Episode 12 costumes truly make μ's look like a team of magical girls. And some of the costumes do make me think of specific magical girl characters. Eli's costume here, for example, definitely makes me think of Sayaka Miki's puella magi outfit.
I hope you do go to Japan some day. Though I'll admit my hope is at least somewhat selfish. I'm sure you'd have some wondrous pictures to show from that trip.
As for your Vivid question - Almost the entire StrikerS protagonist cast shows up in force for a short arc in the middle of Vivid. Caro is part of that, and has a decent-size role to play there. Frequently, Vivid feels like "StrikerS: The Sequel". It's not as much "Vivio's story" as I thought it would be. If you like Caro a lot, I'd definitely recommend watching through this short arc at least. IIRC, that would be about 8/9 episodes of Vivid, so you wouldn't have to watch the whole show to get it.
BTW, a guy I know on another anime forum recently took a trip to Japan and decided to take a few days to tour locations featured in Tamayura, Non Non Biyori and One Off. Have to say I'm now tempted to do something similar (though overseas travel is a few items down my "stuff to save for" list right now and I suspect I'd also be tempted to get some new camera gear first...).
Just remembered something I wanted to ask you about. How much of a role does Caro have in Nanoha Vivid? I dropped Vivid pretty early on, but I actually am pretty curious what she and Erio get up to post StrikerS.
I haven't had a ton of free time lately but to an even greater extent it's been a matter of focus and attention. Those are finite (if regenerating) resources, and when they drop below certain levels I get really reluctant to get involved in much. I'm not even as up on current shows as I typically am right now.
That, and these days I hand out here mainly to keep track of what people like you and Pocari are thinking (I lurked a lot of your posts on Euphonium, Seraph and Charlotte* among others), participating in the threads themselves has become more of a secondary concern.
*I liked Charlotte's second episode a lot, Key humour can sometimes be a miss for me but I like the hunt for the archery club captain quite a bit. And I thought Euphonium was great last season, though I never got quite as into it as with Hyouka. The both had some fantastic artistry and drama, but I think they differ a bit in pace - Euphonium is very driven, Hyouka is a little more meandering and stops for a hundred fun little moments along the way, which amusingly seems pretty fitting when you look at the storylines. Those hundred little moments are part of part of what gives Hyouka it's edge for me though.
Weekend will be busy as it's first of the two big, full weekend anime cons held in Vancouver each summer. And I'm not even done with the photos from the smaller events over the past few months...
Happy birthday - belated I guess when time zones are taken into account.
Attended another mini convention earlier this weekend, will probably drop a preview later (doing a full sort and edit of my photos from the day is going to take a while, I haven't even finished with the ones from last con yet...).
