A decent AOT OVA to say the least. This OVA is centered around Mikasa and Annie's character. The event takes place around episode 16.5 The story was solid. Episodes 1 and 2 were good but episode 3 is a bit of a downer. It takes place in Mikasa' s "alternate reality dream" when she decides whether it is worth living without Eren. The producers do a decent job on shedding their character details and who they are as a person. The characters that cover most of the screen time are Mikasa and Annie but there are some side characters such as Hitch from the military brigade.The rest of the characters are one time characters and aren't introduced in the show afterwards.

Visuals are very good as usual. There isn't much for the visuals producers to work on since there was barely any action in the OVA. It's pretty much in par with AOT season 1.

Not a necessary OVA but still a recommended watch.
