This review title may not be that creative but that doesn’t compare with this story’s creativity. While it does follow the isekai trope (as it obviously should for the context) Katsuhito makes sure that this story stands out with its one of a kind world designs, and with unique worlds also brings unique characters, and Katsuhito also delivers a cast that you’ll easily bond with. The main character’s growth and his dynamic with his Key is so satisfying to see, and you don’t want to skip out on the badass action throughout it all!! Definitely worth the read!!!
