MANGA: Shuumatsu no Waltz

Shuumatsu no Walt – Fukazawa Batsu

In a world that’s heading towards its end, Shirou, a scientist whose sole purpose in life is to create butterflies that can purify the world, encountered a male humanoid named Kuroe. What is Kuroe’s real identity? Why does he proclaim on wanting to meet Shirou?
This is an eternal love story that was born at the end of the world.

The art is beautiful. The sci-fi is awesome. The romance was poetic but too mushy for my taste.
