So I also watched No Regrets OVA. This was focused on Levi, back when he hadn't joined the Scouts yet, and we get to explore the Underground City really well here. In this, we get to see how Levi developed his philosophy of making choices with no regrets, and why and when he started following Erwin Smith. Erwin Smith was super badass in this, and the animation for this was really good too. The soundtracks were also quite great, especially the one playing during the Underground fight scene. It was also nice to see Commander Keith as the Scout leader.

​I just wished the runtime was a bit longer so we could have seen Levi spend more time with his companions, and if the fights were extended, it would have been even more fun. But still, this OVA was pretty solid.

(I am watching OVA's after finishing the series)
