This is one of those interesting gender bender stories, that the guy looks more girl than the real girls but is abnormally powerful. This isnt one of those typical typical ecchi manga you do get the fanservice because of the power of the knight and how the knight gets it but the storyline is actually good in terms of master and servents and the power of her servent and the rarity for a master witch to choose a knight to serve them. The main thing is the knight has to protect the evil witch who is actually pretty cute but there is a reason behind it being a witch ability to become pregnant no matter human or demon or so forth whoever or whatever impregnates her will have the ability to a create a powerful child, that is the main purpose of a knight to protect the witches body from harm. The problem so far is not everyone can become a knight and its rare a knight is chosen as you read the story you will understand why he was chosen as a witches knight, there more to it than the actual purpose as you read and find out, i recommend it because its one of those typical main charactor is weak than become stronger and finds purpose plus the fanservice is an additional plus
