since nobody decided to write a review i will. as the synopsis says, this is the unaired 13th episode that only appeared on the BR/DVD release. i guess somebody cracked the set and uploaded this ep online because it just appeared on gogoanime a day or so ago. basically? it looks exactly the same as the TV eps... but it is the fan service filled, lucky lecher episode that probably couldn't be shown on TV because of all the 'naughty' stuff happening to an under-aged boy and the two yokai girls who appear to be under-aged. don't worry, nothing H rated happens... heck i'd barelyrate this one an R... probably PG or PG13... if Japan showed this one on TV, it would probably have to be after Golden Time viewing hours.

story, of course it's a short ep just like the TV series so... :) not much story, just the usual fun stuff.

art, looks just like the TV series. nothing amazingly new here.

sound, same as art.

character, well Yukihaha is actually a nice lady for this one so she's way outta character. otherwise everybody's normal.

enjoyment, of course it's funny! :>

overall, if you liked the first 12 eps, you'll like 13. :D
