Violet Evergarden, Fumetsu no Anata e Recommendations
If you enjoyed the drama in violet's story u might also enjoy the well-written story of the immortal creature.
I find the MC quite similar because they don't know much about themselves or the world and throughout their journey they learn a lot about it. Both of them meet a number of people who have their own stories and situations.
A protagonist with little emotions learning the tragedies of human lives.
Both MCs are cold and emotionless at the start of the show. Both of their story progresses by them encountering different types of people. Violet meets several people to understand the meaning of "love" while the orb (name of MC is sort of a spoiler) goes on a journey and spends time with the people that it meets as it learns how to be human along the way. Oh yeah, both shows are also depressing af.
Both the MCs are inexperienced on how a normal person lives their daily life. They both are very strong, you may even say overpowered compared to the other casts in their shows but they carry a heavy burden on themselves one full of regrets. Both the storylines have very well written plots.
Both anime are about the journey of empty shells, who develop human emotions through the series of people they meet.
Both are about hollow people who dont understand human emotions and they slowly get better and better at understanding humans and their emotions.
