This is cute but there's one thing that doesn't let me immerse in this completely ... And that's the fact that Ui just managed to let go of her sister, so unless I watch a previous arc with a shonen battle Ui vs Azu I just can't accept this
Yui being yui it wouldnt be so strange that could pick off azu-nyan if there isnt anyone of the opposite sex that is appealing XDDDD
Like azusa said she is so strightforward that it kinda flow naturally this ship
