it’s where a swordsman is summoned to be the hero by a princess, in her room I think. But instead when he hears guards he puts the princess on sword point and threatens to kill if she doesn’t take him to the person in charge ‘the king’. After a long talk he kills the king and I think leaves the queen and the princess but I’m 60% sure he also killed the queen. He’s all about killing but gets 2 (beastmen?) Girl slaves that can fight by his side and whatever...... Please help me
It's one the two, there are no other jp stories with a summoning and killing of the summoners. At least i think so. Well there is a revenge story where MC is back to the summoning moment but that doesn't really count.
