Sagitter's manga / #Werewolf(3)

In which our mc was isekaied and turned into a werewolf mage and has to fight against humans. He defeats one city but instead of killing everyone, he decides to instead keep everyone alive and use it as the center of trade for his new city where monsters and humans can coexist. This is really interesting because the mc has a brain. He thinks about ways he can use the city instead of killing everyone. Also, he thinks like a healthy adult instead of being all like "HOLY SHIT I CAN NOW DO WHATEVER." He does things that are beneficial to all and is all in all, pretty cool and badass.
