- Monsters threatening the existence of humanity
- Same animation studio (Wit Studio)
- Same music composer (Hiroyuki Sawano)
- Post-apocalyptic setting
- Similar art style
- Steampunk setting
- Mankind forced to live in enclosed locations
- Hometown of protagonist invaded by overpowering force
- Side characters are dying quite often
In order to to save humanity from the brink of extinction from a mysterious catastrophe, the remaining people have built a barricade around the area that they live in. In both series, only a few special individuals have the power to fight the monsters. While SnK is set in a medieval-ish world, Black Bullet is set in a futuristic one.
They both share the same characters; you can literally match the characters from both sides.
The plot is also the same; humanity is on a brink of extinction because of a source they know very little about and now humanity is fighting back.
If you liked Owari no Seraph you will love Shingeki no Kyojin!
Both shows are sequels to two of Wit Studio's biggest works. Each show picks up right where the previous season ended. Humanity is on the brink of extinction in each show. Titans have almost devoured all of humanity in Attack on Titan. While in Seraph of the End vampires have almost wiped out humanity. Each show has giant monsters that humanity has to take out, although they are not the main threat in Seraph of the End. The main character in both shows has a mentality of wiping out all of the enemies because they killed his family. The main character can also transform into something else. In Attack on Titan Eren can transform into a titan. While in Seraph of the End, Yuu can transform into a demon. read more
I recommend this show due to the central themes. Both are about humanity struggling against overwhelming odds against monsters. Both have organizations and solutions to deal with the problem. Also both main characters seem to share the trait for vengeance.
