Opus.COLORs was an Ok anime at best, they put the whole devolepment in only 2 characters, and say "fuck it" for the rest of the cast. The only thing saving this anime of beign just bad, its the super emotional final. When I watched episode 12 I was SOBBING. This is so good but I am so sad that this anime is so mid, no world construction or side characters devolpment. Still pretty OK. If the ending was a LITTLE worse it would be a 5/10 easily. I'm glad they knew what they were doing, they knew really well their whole point was only 2characters and they did it REALLY WELL, side characters are only supports, they dont even have a history by themselfs.
