A pretty good One Punch Man ova. It simply goes over on how Saitama got his suit and how his life was like before he lost his hair and became the strongest man on the planet. With similar tones and writing to that of S1. The animation was pretty good, they didn't have do much work on that since there were barely any fights and the entirety of the episode took only in one place. The music was good and was similar to that of the S1. For the characters he entire focus was on Saitama and the creator of his suit so there wasn't really muchto go on around about that part.

I liked it for the most part and it was the length of a full episode compared to that of the One Punch Man Specials which were only 12 min long.
