Yeah, right? After all, [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/TrueArtIsAngsty]True Art is Angsty[/url], not?

Anyway, I'like to say that if things continue like this, it won't be long before Iruka begins calling Ryoka Onne-san, or should it be [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/OneeSama]Onee-sama[/url]? Hehehe.

Exactly! We're in Shine City, dammit! With all the common folk so sparkly, most of our characters must have problems! 

Honestly, I think both work well, though the Cool Big Sis one seemed also pretty appropriate (though Ryoki's in her late twenties >_>). Screw it, she's practically bipolar - give her all of the tropes XD 

Also, I found ANOTHER theme for Ryoki. This one seems really fitting, though :P

And as for the metal theme... 

I can't find anything ;~;
