I just finished Ga Rei Zero, and I'm kinda torn on it honestly. On one hand, I really enjoyed Yomi and Kagura's relationship, the animation was pretty good as were the character designs especially the females'. But on the other hand, I couldn't buy Yomi turning evil, it's seems out of character for her to murder her friends without any remorse. I just hated how she turned evil. She became a really unlikable character from then on. It's seems unfathomable to understand a character such as Yomi to be evil and killed without remorse with no real explanation. Which is sad because Yomi was my favorite character. Small plot holes and an animation error held the show back the show from being great as well.
I have no intention of reading the manga after watching this. I just felt disappointed by this anime. It could have been great but because of all of the inconsistencies, this was a decent anime at best.
6.75-7/10 (I felt that it was good for most of it's duration but the latter really went down hill after that)
...And then you have my permission to die.
