Rainbow: Nishakubou no shichinin

Truly when speaking of a Seinen, Mature, Adult-like animes Rainbow is definitely one of the top ones. This show almost leaves no place for the comedy side of anime which I like. I prefer less comedy more seriousness and this anime delivered it to 100% The story, drama, characters, development, build up, this anime got everything, there are happy moments, there are sad moments, and as we follow these 7 individuals in a tough environment, each with different backgrounds and struggles and dreams, you start to like them one by one as they progress with their unbreakable friendship, in this anime you will see the very represenation of what True Friends Are For. I recommend it 10/10
