The Hero Laughs While Walking the Path of Vengeance a Second Time, Vol. 6 (light novel)

Metelia ambushes Kaito just after he completes his latest feat of vengeance, forcing him through a portal to his home of present-day Japan. Stripped of his memories, Kaito comes to terms with his tragic new reality—a world where almost everyone he knows is dead, having been sacrificed when he was summoned as a hero the first time, and the few survivors of the incident are being hunted by a group of conspiracy theorists. Even this fragile status quo is disrupted when an assassin nearly succeeds in taking his life. But the brush with death restores Kaito’s memories and powers, giving him the perfect opportunity to take revenge on his assailants and chart a course back to his partners in crime.
