Isekai Tensei: Recruited to Another World Volume 9

Three years have passed since Tenma’s last adventure, and life in the capital has become routine for him and his companions. As one of the kingdom’s most esteemed adventurers, Tenma is renowned far and wide. But trouble brews when Margrave Haust, with whom Tenma shares a tense history due to the events in Kukuri Village, requests his help to defeat a rampaging swarm of wyverns. Driven by his friendship with Leon and a desire to mend old rifts, he agrees to take on the mission. As he sets out to confront the deadly creatures, however, he quickly realizes that these creatures are merely the beginning of a much larger, more dangerous ordeal. Tenma’s next journey will not only test his strength, but also force him to confront the shadows of his past.
