Except for the last two episodes, there is no plot in none of the 10 episodes. Some are just background of Libra members (4,6,7), others are nonsense ( 1,8,9) and some are rushed (2,3,10). The episodes 8 and 9 are the worst of the season. The episodic episodes feels like a bunch of OVA mixed together.
Art (7/10)
In this aspect the show in much better than the other options. The fights have very good animation and the colour is beautiful.
Sound (6/10)
Besides the opening and the ending, i don't remember much of the soundrack.
Characters (3/10)
Despite the show have episodes dedicated to Libra members, after that, their presence feels nonexistent. Also they still are some Libra members that barely know anything. Leo is undeveloped until the last two episodes, he is just beaten all the time. Klaus feels more a background character in most episodes unlike the first season. Zapp have less screen. Steven in the only character in this season that was well treated.
The villains: all are generic, boring and are the same just with different designs. The Blood Breed of episode 10 and the villain of the last two episodes are the only with personality in the entire season. They are so bad written that i just remember the villains of the first season. Aligura and Femt barely appears despite being in the opening.
Enjoyment (3/10)
I don't like most of the episodes. Nearly all the episodes are just the same: some generic villain do something against a Libra member → characters try to finding them or do something to defeat them→ explosions everywhere and the generic villain is defeated. Even in the background episodes this happens.
Overall
I don't like this season. Despite the first season was average (5/10), this season feels more chaotic and a wasted of time in most of the 10 episodes. This season handled very bad the villains and forget Femt and Aligura. Only for the animation and the last two episodes, my score for Kekkai Sensen & Beyond is 4/10.
