At first the anime is hard to watch but it gets better towards the end, for the first half ill give it a score of 3 of 10, for the second half, ill give it a score of 7 of 10.
The story itself is a failure, sorry but its one of them anime that is almost a chore to watch. The art is a little lacking, it looks older and not as clean as newer anime. The sound when they sing isn't bad, so ill rate that a little higher. Character development is average, nothing special there till the end.
I enjoyed the ending,
but not the beginning, so ill rate it 7 of 10. Would I recommend it to watch? Yes if your able to binge watch it from beginning.
