Dorei Shounin shika Sentakushi ga Nai desu yo?: Harem? Nani Sore Oishii no? · review
Looks like this manga was concluded a long time ago? The MC (not isekai) randomly was chosen for several jobs between hero, slave master, etc? Due to this, the power scaling is very confusing and we are sort of forced to accept whatever he does. The story itself is nothing special as it is suffering due to random pacing and reactions that don't mean anything? The only good aspect is the MC's resolve to buy slaves and send them off to live in a village peacefully. Usually, other series featurin the job of Slave Master's tend to be....lust filled, so I enjoy how the MC is going the hard routeto address slavery in his own way.
