This story's summary seems to be a lot similar to Special A but in my opinion, Last Game is better of various reasons. ( it's just my opinion, ok ) This manga doesn't focus much about the challenge either and it is very innocence and pure. The story is actually very simple but very entertaining at the same time. The art is cute and ok and the mangaka did not dramatize much on the character's experiences. I read this manga twice and it is always been funny. Definitely for people who need comfort and prefer light and innocence manga.
The only criticism here is the ending is not as I expected to be to be exactly Kujou's career but it was simply a masterpiece!!!!
