The Horizon

Both very slow building, emotional and character driven. No other works have portrayed despair as well as these. They are both very nihilistic, but with a hopeful message toward the end. Pun pun is pretty depressing the whole way until the end, while Horizon is an emotional rollercoaster. I can guarantee these manga will give you the feels affect you much more than any Shonen trash.

The main male characters in both shows are son of a lord and are inflicted with something supernatural which causes their father to want to kill him. They were both thought to be dead, but actually are still alive. They are also both a threat to their homeland due to being alive, with one being an offering to demons, and the other housing a water demon who could cause droughts. Female lead has to teach the female lead more about the world that they were ignorant to. These shows are basically identical to the point of plagiarism.

Both anime tells the story through multiple perspectives to drive the plot. Both require decent levels of iq to appreciate for what they are. Both have very dark themes and make you question your morality. On most of the anime lists I have seen, if you put Ginga Eiyuu Densetsu as a 10, you also put monster as a 10. Both these animes are absolute masterpieces and deserve to be watched.
