To clarify 400m isn't half a mile it's a quarter mile, more specifically slightly less so. But an eighth is fine too.
Everything's A-okay. Since the things you mentioned only ever appeared once or twice on the anime's.

So as long as I play her abilities to within the reasonable restraints you mentioned, she's fine?

Now to more supplementary material... If a picture is worth a thousand words, then videos are worth so much it'd be practically tiresome to count. On hindsight I should have checked youtube since these videos probably explains in better detail than I could have. But that's done now.

A fortunate coincidence maybe, since there seems to be a great lack of Yozakura Quartet content on youtube. There's quite a few that has her in it, she seems like a popular character for the series' fans it seems.
