...L... Watari got tired of feeding Du sweets and watching you, because he's obsessed with them too. He started having really bad withdrawl symptoms. Du ate all the sweets. So he left his place being your samurai manservant, and took all the sweets with him. Now he's a homicidal sadistic hermit who lives in the suburbs and eats all the Süßigkeiten he can find. He also has agoraphobia now so he huddles in a corner hissing at people as they walk Von and try to steal his food. And now, all the Schokolade Mello eats, goes straight to Watari's thighs.
