@DragonRider45 The thing is that there was not a tragedy tag before... It appeared when readers asked for it when everyone died...
For me, it's ok if the author kills everyone but this is badly done, we have a "bad guy" we've never seen, he kills everyone and ... he dies... It feels lazy...
It's like in Lord of the ring the author gets bored so suddenly a big bad guy comes and kill everyone but Frodo and then he dies... Ok, fresh start but wtf
Really hope this manga will be picked up again, really liked the fact that it was not same cliché story as with most "slave gets adopted" manga where they all live happily ever after
