Battle Spirits: Brave

First off, I'm going to start by saying this: This show can be watched as a stand alone, but I would not recommend it. It would be better to watch the prequel (Dan) first.

After the dissapointing execution of an interesting plot in Toppa (first battle spirits series, absolutely skipable), came Dan. To me, in started becoming interesting half way through. I had hopes for it's sequel series Brave, and I was dissapointed.
I found the first half of Dan to be a typical episodic card based isekai, and the second half to be much more plot focused, and my enjoyement went up. In Brave ... however, the series starts off strong, and keeps it's momentum for most of the watch through. I was dissapointed because I expected it to also grab me after a twist, but I was already grabbed.
TL;DR: Dan was good because it had a slow start, but Brave is good throught, and thus has no surprise 'wow, that's awesome' moments.

The story is interesting. It revolves around character relationship a lot, and even though I dislike Youth (one of the most prominent side characters), he develops well. Also, if you're expecting more from Kajistu and Yuki, they exist, but aren't very plot relevant.

The series isn't very linear, and the plot is all over the place. However, it reflects well on how they deal with everything happening around the world, and I like it. I'd give an 8 for story, and a 9 for characters.

Art: 7. I don't have much to say. I'd also give the sound a 7.

Enjoyment: 9/10. I would also feel confortable giving it an 8, since, like the previous 2 series, the card game isn't super interesting IMO.
Total: 8/10.

If you liked Dan, you should like Brave.
Nota:
Yes, Dan is more mature.
There isn't more focus on the relationship between Mai and Dan than in the previous series. It's just accepted that they like each other, but Dan has another passion. Not much more than that.
As I said, the story is all over the place, but if that doesn't matter to you, then that's one of the charms of this series.
Indeed, the only characters from the previous series with an important role are Dan and Mai.

The story starts 2 years after bahin dan's fight with other world king. Here Dan wins all the battleship tournaments and craves for powerful rivals and thrill of watching the spirits alive as it was possible in the other world. When he was in such agony, Mai comes from future and takes him to the future. Future world is ruled by mazoku (other world beings with monstrous appearance and powers). There is conflict between mazoku, the ruleers and mankind the slaves. MAI joined the world saving human organization where clarckey works as the captain of a ship, which he named as "beautiful sophia". Here dan's ... battle with Barone, a mazoku leader of rome, changes both of them. He in the future world considered a legend of battle spirits game. As the story progresses, our hero has to collect 12 zodiac cards to stop the planet from being destroyed.

Art: too good.

Sound: good. Especially you can observe it while the battle spirits fight goes on.

Characters: Barone character is the one which seems to change a lot. He thinks of the humans in another perspective . Most amazing characters- though were not shown quite frequently -are the queen of mazoku and the wife of a captain of mazoku -Duke (who work hard for both the species). Both of these ladies understood their environment and planned well their future. For instance, Queen perceives that here court officials are trying for a coup d'etat, plans beforehand. She even understands others though the way they battle. She bowed to Dan when duke was defeated in a battle with Dan. She hold on to her promise with Dan. But her bow to Dan makes her to face severe consequences, she never quivered. Again duke's wife seems to understand the emotions of people around her. In the final episodes, she comforts mai well. She even accepts a human as a son so that her husband's ideal may be achieved.

What i do not like in this series:

1. To show Dan more mature and serious.
2. To forcefully show romantic relationship or at least hints between Dan and Mai.
3. Search for the 12 zodaic cards is not executed well. I mean to say is that for some episodes these were shown and for some Dan says we got 8 we need some more. No struggle at all shown for achiveving the cards from Suzuri's prospective.
4. Clackey is left completely side character.

Finally i disliked this series. So i gave very low ratine in my watch llist.
