Juuni Taisen is a 12 player battle royal where all the players represent different signs of the Chinese zodiac, for me, this is well enough to get me interested. On top of that, it's pretty short, for reference it took me about 3-4 hours to finish it.
I mostly enjoyed it, but I saw that it had some "faults", it didn't really impact my enjoyment of the manga, but it just made it a bit duller.
The premise of the story and the characters was what got me reading, the story turned a little meh at points but the characters were still very enjoyable so I didn't
really mind. The only fault here that I felt while reading was that we didn't get to know them enough.
For the story, while it started very promising, I felt it got a bit predictable after a couple of chapters, but I will admit that later on ca ch. 15 or so it got more unpredictable. Basically, the story had its meh parts, but it was still very much enjoyable.
Lastly, the art was very nice, I felt it fit the story and the characters and was overall enjoyable. Though in some fights the art felt very "cluttered" (side note on fight scenes: most of them are very short so if you're going into this manga hoping for fights you won't find them).
