I thought this was going to be quite boring, or super generic, but it's actually not that bad at all. It's a shame that no one seems to be translating this. I would absolutely love for this to continue.
I forgot this manga because of the slow updates. Just for this to be the end? At least it's somewhat fulfilling, but I hope that the mangaka for this series tries something again, because it honestly wasn't that bad.

I also have a question, where is this based at in the light novel? Or is it manga original or something. I read what I thought was the light novel to the end and everything is about the same up until this new "Santa Claus, cheer-up" arc for Harusame. I was wondering if I missed something or if...
