Yoshida, who worked for a black company, died in an accident. Due to a mistake during reincarnation work, he couldn’t be reincarnated in his original world. God suggested him to reincarnate in a different world with a mischievous angel, who unwillingly accompanied him, as his support; and the two were born into the world of sword and magic as twin brother and sister. A few years later, Yoshida took magic lessons from his angel sister and began his special training so that he could lead a fulfilling life. But the younger sister, who changed her mind to enjoying this world, was aiming for a parasitic life where she could live comfortably, so she continued training her brother so that she could use him well. Being an adventurer, or the third generation of inn owners, Yoshida’s second life with a younger sister, who doesn’t wanna work, begins. Source: NU

From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): One day, a girl named Nagatsuma Saki meets a little creature named Tsumasaki Otoshi. Otoshi's role is to cut off the toes of unsuspecting peoples' shoes, but ordinarily humans are unable to see him. Saki is an exception to that rule, and he finds her pushiness and lack of fear terrifying. Saki seems to show up extremely often while Otoshi goes about his usual business of shoe-snipping.
