yosuga no sora shaman king episodes 1-64
He aids the main character in many instances, yet his motives behind why he supports the protagonist are rather lacking as well, as he apparently was smart enough to solve various issues. Finally, the last character of interest is the murderer: although he is portrayed to be a mastermind behind the scenes, avoiding detection over the span of several decades, he makes tremendous mistakes when the main character is concerned. He ultimately degrades to a simple one-dimensional villain with no convincing motive at all: furthermore, this also raises the question why said person took so many poor decisions and why he just didn't switch his killing target(s) when things became too heated and unfavourable.
The various interactions between the cast are handled poorly in most cases, be it the one dimensional evil parent or perverted manager, or the supporting cast whose poor choices leads viewers questioning their mental age; or just the fact that most act as passive observers. Because of the stale personalities of the cast and their changes in behaviour, the interactions between them feel unnatural: however, this mainly affects the main plot points. For the slice of life moments, these were often well handled by the studio - those were often the most enjoyable parts of the anime, which is a huge disappointment, as it is not the main purpose of the show.
~Animation and sound~
One thing that can be given credit to the studio is its direction and use of animation: this was well done, displaying the various themes the anime had to offer such as loneliness, isolation, happiness, you name it. Through the art it is able to portray the different emotional states as well as physical conditions of the characters; despite executing this well, it is rendered useless when the narrative constantly shows constant abuse, making these little detail utterly pointless, which is a waste of resources. An example would be the focussing upon the bruises of Hinazuki. As for the art style itself, I personally didn't like it and found it off in some situations, be it in the character design or the different facial expressions. The anime also tried to mitigate the problem regarding the mystery behind the killer by applying red eyes to suspects, yet this is a cheap alternative to creating tension, and when everyone is can have those eyes, it loses its purpose.
