-My opinion only...You have the right to disagree-
Though I have watched only 2 episodes of this 'GEM' I find this as an outstanding creation of the year 2016..
Many good ones have appeared until now but this on stands nearly at the top.(Nearly because of berserk, Re-Zero and such)
The concept of being a high-school student once again to improve the future is quite intriguing(I would like to try it once I get older) and there is comedy at the right moments..
Well that is all I can think of to write right now, and I recommend everyone to watch this...Happy Watching..
