There are a lot of hero/isekai/betrayal stories out there, that try to do the whole revenge thing. But this is pretty much the only one that's actually any GOOD. Because the plot is interesting, the characters are memorable, but most of all, he's creative and entertaining in how he goes about seeing his own brand of justice dealt out. And this latest revenge is proof of it. The kids were assholes too, but he still let them off (mostly, they'll have to fend for themselves from now on, which I choose to believe is their punishment). The adults suffer the same pain as the soldiers they denied, have their crimes revealed, and are then painfully killed by the living relatives of the people they victimized and wronged. And all it took was a few well-placed illusions and some clever telekinesis tricks, like untying the ribbon and sending it flying.
Fucking top tier revenge. 9/10. This manga was already the best edgelord betrayal-revenge story I've seen (though that's admittedly a pretty low bar), and the quality of the scenarios just keeps going up. It's good. It's real good.
