let's just say he's the opposite in most harem MC's who keeps roaming around the edge when it comes to romance. He went straight for the goal on the same day he acquired his slave lol. You'd think its a good thing that he isn't another Issei-san in a harem series, but the way he did the deed? yeaaaahhh. I'm a guy and even I find it a bit creepy.

Is he abusing his slave? Well, we didn't get any Intermission chapters featuring the slave yet to know how she truly feels about it. When he does his thing the narrative tries hard, very hard to justify whatever it is he's doing like there's nothing wrong at all.

The slave-girl gradually warms up to him and admires his strength, but really that's just because of the setting and his mandatory OP power as an MC.
