Kaiba, Casshern Sins Recommendations
It's distant future, the golden age of humanity is in the past. Main character finds himself in a strange place and realises he have no memories. He starts the journey and piece by piece finds out who is he. Both anime are gloomy, with strong spirit of loneliness and bittersweet ending.
- Main character lost his memories and have a invulnerable body.
- People have an artifitial bodies.
- There is a battle for the throne of the world.
Both are self-contained. Questions what existence means: existential thought. Plot-wise Kaiba is more unconventional, while the pacing in Casshern Sins is relatively linear.
