Likely not any time soon, because this is literally all this manga has going for it plot wise. There is nothing else. Nothing ever really got established, nothing really had been built up for a later point in time, and due to the setting, there is no "new" characters. Everyone already knows everyone because MC came back to the same world after just a few years.
This started out great, but quickly became a mess the moment MC became unable to kill those he needed to. I don't get why that part was introduced at all. It doesn't fit the story.
If you want a no kill Hero, the villians need to be redeamable somehow, or off themselves in order to allow MC's major handicap to work. If your enemy is killing you, and you just beat them up, and let them go because you can't do anything more than that, they will come back and try again, or harm others because you cant truly stop them.
Neither of those "redeeming" enemy types happen in this story, as of yet. But MC is 100% a shounen hero in terms of what he can and can't do. Basically the story is stuck. MC can't end the fight himself, but he alone is the only one strong enough to do it. The rest struggle along and have bairly managed to not die.
