I find it challenging to rate this. It's no surprise that this is the first review after almost 5 years after it aired...
This is basically a 3 minute comedy with no relation to the storyline whatsoever and...there's not much of a story either...
Can't hurt to watch, right? Something which has the purpose of creating amusement to a more serious anime.
It also reveals a more lenient side of Kaname, which is interesting considering how serious he is in the Anime. I'd say it's a challenge to write this review without spoiling anything, as there's not much to be shown in 3 minutes other
than it's off-track comedy.
(Message me if you can't find it but want to watch it.)
