I saw this anime some time ago, but I must confess that I don't remember anything about it, however, I know that I found it very interesting at the time. And well, you're right, 12 chapters are perfect to watch at this time of the year.
Thanks for posting on The Anime Realm. Greetings!
Well, this means you should watch it again, hahahaha, to refresh your memory and to see if you agree with me. Take advantage of the fact that it's short 😁😬
