As a huge fan of inazuma eleven, I can safely say that this is a masterpiece without a doubt. No explanation needed really. It speaks for itself. The plot is perfect. I couldn't find any plot holes whatsoever. All the characters are great. The artstyle is amazing. We got to see an anime version of gru, thats the only thing you'll ever need in your life. Whenever i get sad, i look at anime gru and i think to myself "yes". TL;DR: if you haven't seen it already watch it right now. This anime is nothing short of a masterpiece. Drop whatever you're doing and watch it now.
