The Good Deeds of Old Adventurer Kane

Kane is a middle-aged and unambitious adventurer who, while in the middle of herb gathering, finds the rare item "Resurrection Fruit." Kane thinks about selling it and turn it into money, but he meets a girl seeking medicine to save her companion's life. Since she looks like Altena, his late childhood friend, he gives it in exchange for small change. Actually, the girl is the strongest adventurer Anastrea, who people call "The Sword Princess." The next day, Kane suddenly gets an invitation to join an S rank party, beats down the strongest and the worst monster, miraculously gains lots of money, and finally gets a confession by a 13 years old saint. Kane's simple life will change completely because of his encounter with Anastrea.
