Thanks :) The pixel art icon is a self portrait made by me and the profile background is from 'The Dark Eye: Chains of Satinav' xD I don't even remember the tools used to make the animated raining gif xD

No, it's from Heartbound

It's from Shigurui. The manga is about the fight between Fujiki Gennosuke, who is the definition of samurai, completely loyal to his lord to death and Irako Seigen, who is the exact opposite and too ambitious for his own good. Seashell is the analogy for samurai whose only purpose is to protect his house. Both manga and anime are great, but it's adult rated.
