I have a feeling it might turn into incest at some point...

Fortunately I don't think so. The chn only do the fauxcest ones at most, the stepsibling, cousin and "raised as family" ones... his sis is his spitting image so I guess they're full siblings... ngl... when she appeared and looked just like him... boy was I relieved... cuz I had the same fear as you...

I agree with you also they aren't doing the weird fan servicing they do when you're about to do some sort of weird fauxincest thing. He's not blushing when he hugs her they seem to talk about things about him thinking about how beautiful his sister is it's just a handful of little hints that it's not going to be incesty

Yep! And to be honest, even his relationship with the other girls that appear is not that bad! I mean, asides that classmate at the beginning that was weirdly competitive and whe white haired assassin that clearly likes him and they partied together for quite some time... the others are... normal... they meet, become acquainted, meet and help each other a couple more times and go their merry ways... they admire him for obvious reasons but don't act like he's the last man on earth or something... even the guys admire him to a certain point and don't just keep picking fights witb him... those points make me like this one more than the others... I would like him to change clothes at some point tho...

Man I know he don't even upgrade his clothes when he gets new armor. He just be using the same t-shirt and pants he'd been using since he got into the school like you could at least change the color. I don't know why it's so hard for them to at least change the color they don't want to change the style of clothing or something cuz I get it I don't want to draw all that either but y'all out here with the same white T-shirt blue pants or whatever he's been wearing while everyone else is dressed up like fantasy characters and that's the thing that's killing me Like simplify everybody else's outfits and give him something new every I don't know 50 chapters or something.

I don't even need something new every 50 chpters... as long as he wears something more fitting to his class is enough... even black pants and a dark grey shirt would be enough! Of course if he had a jacket that looked a bit like a mage's robe it would be even better... even his master looks more like a necromancer than him...
