To counter all the female-knight-loss hentai I thought I'd recommend a manga called It's My Life. It's about a Fantasy Knight at the end of his career retiring to a cozy log cabin that struggles to find meaning in life until he adopts a very cute daughter-wife. It's mostly about the two of them being visited by former party members or the local fauna and remodeling their house.
It's written by a dainty westaboo lady that likes dadrock you should check it out.
