Elf, Jukishi wo Hirou

Vanicia, an elf who is surprisingly all muscle and no brains, and Dico, an anxious and introverted heavy knight, are two adventurers living together. Found collapsed with amnesia, Dico was taken in by the caretaking Vanicia and became her live-in companion. He finds his heart racing and his life turned upside down by the adorable, defenseless, fussing, and headstrong Vanicia... While taking their time to slowly uncover Dico's past without any rush, the two live a peaceful life together.
