星霜の心理士, The Counselor Through the Years and Stars

The hearts of the hero's party were worn to the brink— In a world locked in a bitter war between humans and demons, the hero’s party is hailed as saviors by the people. Yet behind the praise lies the unrelenting toll of battles where death is a constant companion. Sofia the Sage, desperate to save her comrades from emotional collapse, summons a glimmer of hope from modern-day Japan: a psychological counselor named Hoshino. Though unfamiliar with swords or magic, Hoshino begins to practice her therapy—"counseling"—on the broken heroes. Her methods gradually start to heal the party’s inner wounds… and in time, her presence begins to reshape the fate of the entire world. A unique and heartfelt isekai tale where mental health meets magic and war.
