just take the mage's rings off or cut those then see how many shots left for the villain, that should make him pale. the twin's death is unavoidable if no new factor happen, make it quicker the better.
i guess if aurthor takes it that far he has to kill of that guy brutally in the next chapter. if he doesnt then the author himself deserves to get his contract brutally tortured
You know, and there will surely be a lot of angry people disagreeing with me, but even given the fact that children are usually stupid, author portrayed them in such a way, that i am not even feeling any pity for little shits.
