If you do not like love stories then do not bother watching this. To be honest I cannot go into detail about the story because its so short. Just take my word for it and watch it. Within the first 12 minutes I was already developing tears, 20 minutes in and they fell down my face. Its that sad.
The only real fault here is the art style. The characters look awkwardly proportioned with the detail being a bit off. The CGI for the mechs and whatnot look very cheap but again, this does not matter for the purpose of getting the message that it conveys.
The only other kink in this OVA's armor is that the music didn't stand out. But at least it wasn't annoying or anything. The voice acting on the other hand is perfect.
I think a 9/10 is perfect for this OVA with only 1 point taken off because of the art. If it was completely 2D like say Gundam then I think this would have been a complete 10/10 for me.
