What's a manga that, in your opinion, has a really unique story?

I really like this one because I enjoy stories where main characters are trying to find purpose in their lives. It's a nice slice of life with really good themes and advice I was able to apply to my own life :)

1/2 prience
Chouka Kou (history but so good)
Kanata Kara
Ohayou, Ibarahime ( so different and good story)
Koushaku Reijou no Tashinami
Niehime to Kemono no Ou
Skip beat
Ou-sama Ni Sasagu Kusuriyubi
Sennen Meikyuu no Nana Ouji
My dear blood king (webtoon)
Keishichou Tokuhanka 007
Taiyou No İe
Miss Not-So Sidekick (webtoon)

I love impactful stories like this. Thank you!

Whoa! Thank you so much for all these suggestions!

I thought this one was pretty cool

This one was the last one I read that made me go "Wow!" http://www.mangago.zone/read-manga/the_red_world/

I love Bikke's work.

I loved the novel better than the comic adaptation for 1/2 Prince. (ps I read the manga first which I recommend if you you're into reading)
