Ningyou Shibai

 ...then you might like
Fushigi na Shounen
|
Series of one-shots with recurring characters and a philosophical outlook. They both deal with topics such as death and the reason for living in a positive sort of way, though Ningyou Shibai is more hopeful. The recurring characters are not human, and teach people about these things (though the boy in Fushigi na Shounen is still learning them himself).
