Wasurerareshi no Eiyuutan: Seiyuujo Party ni Yasashiki Tsuihou wo Sareta Otoko wa, Kioku ni Nokorazutomo Kanojo-tachi wo Sukuu

Kazuto is a young man summoned to Fernad, a realm of swords and magic, where he dedicates himself entirely to the bonds he shares with his comrades. Empowered by the Goddess of Bonds, he gains extraordinary strength, but this gift carries a devastating price: he must serve as a "Lost Namer." Whenever he parts ways with those he fights alongside, their memories of him are completely erased. Despite this cruel condition, Kazuto endures countless harrowing adventures, ultimately earning a place within the S-rank Saint Brave Maiden Party. However, on the eve of the ultimate confrontation against the Demon King, the party's leader, Romina, gently expels him from their ranks. True to his curse, Kazuto instantly vanishes from the minds of the women he swore to protect. Six months later, living quietly as an ordinary solo adventurer, he receives word that Romina and her companions have triumphed over the Demon King. Though they no longer know his name or remember his sacrifices, Kazuto returns to town carrying no resentment. His heart remains steadfastly devoted to them, continuing to cherish the bonds that only he can still remember.
