So apparently episode 9 was not the last one (eventhough the animate website didn't give a date for the next episode like usual and let it intentionally blank up untill a days ago)
But then again, the silly overdramatic skit at the end of episode 9 kind of gave away that there was possibly another episode.
I haven't finished listening to episode 10 because i was converting and uploading it, so i am not even sure if this one is the actual final episode.

edit: those Inui Sana garagekits from Volks are going for pretty high prices in the japanese auctions at this moment.
I forgot to save the link of that auction, but one went for over 20.000円
