@LysandersTreason I don't know why you would ever call him a eunuch when he didn't even get neutered or have ED and the like... all he learned was suppress his lust for sexual craving and carnal desires and more or less devoted hundreds of years to swinging his sword to no end. And that only netted him 4 Sage Skills (not counting the way they elongate their lifespan). A protag that devoted himself in getting strong is basically better than outright Powerful MCs right off the bat... but that then
HEAVILY depends on the author on how to handle that MC and the world around him/her/it.
It's not that he doesn't have any, it's that it was just kept suppressed for the sake of another thing that he devoted himself for. So if Brauer does her awkward courting towards Sansui right, he'll completely take her seriously.
And it's fine this way. Action Isekai stories shouldn't always be Auto-OP charas as MCs nor libido-driven charas to make it interesting, our MC is fine the way he is, he just need to be involve more in the human world and their way of living. This was given as a task to his master and he gladly accepted it alongside raising Rain.
About attendants, it's more common to see it on the 4 Houses, if my guess is right, they're more damn privileged than anyone else if I also get that one right. (I'm completely interested in this series so I might get the LN)
@LavSingh you'd be surprised what that Divine Blade has... for character... :|
or not... :|
