Plot Summary
In Iraq, a group of archaeologists discover ancient relics that prophecize the coming of a superior race and the end of all civilization. Meanwhile, back in Graviton City, as A-Ko and B-Ko's rivalry over Kei intensifies, Mr. Daitokuji sets up an arranged marriage between Miss Ayumi and Kei. Furious over the engagement, both A-Ko and B-Ko do whatever it takes to prevent the wedding from going through. Little do they know that another alien fleet is on its way towards Earth.
My Thoughts
The Project A-ko movie series reaches its finale. It begins with the school teacher depressed, longing for that special someone. B-ko's father is playing matchmaker and arranging K to marry her. A-ko and B-ko don’t like that at all! C-ko is, again, pushed to the side and ignored. All the while, a mysterious fleet of ships approaches Earth for… an invasion? This movie is a bit slower than its predecessors. The ending is sweet, though.

Project A-ko 4: Final can be downloaded via torrents from Nyaa. This site is the best, safest, and most dependable resource to get anime for free.

Notes
- If you don't know what torrents are, YouTube has tutorials. Be mindful that torrent downloads aren't instant. Depending on your Internet speed and number of seeds, it could take up to 24 hours for an anime to download.
- If you need a torrent client, these are the best (they're all free).
- The majority of video downloads from Nyaa are in “MKV” format, and less commonly in “AVI”. If you need a good video player to play these formats, VLC Media Player is the best (and it's free). It's available on every OS, including iOS and Android.
Is the MKV too big?
If you download a large Blu-ray quality MKV from Nyaa, it is possible that your computer or phone/tablet isn't fast enough to play it at full speed. In this case, you can use HandBrake. It's a free video converter; use it to shrink down the video. If you need help using HandBrake, YouTube has tutorials. Another option is to use Plex (mentioned below) because it automatically downsamples large videos when it streams them to your TV.
Playing on your TV
The easiest way to play MKV and AVI videos on your TV is with Plex. It streams movies from your computer to your TV through your Wi-Fi. It's a free app. Install it on your Windows or Mac, then install it on your set-top box (Apple TV, Roku, Fire sticks, etc.). Just note that Plex will only detect these movies in an Other Videos library because the “Movies” library doesn't detect rare/obscure anime classics. If you need help, YouTube has tutorials.
