Isekai ni Kyuuseishu to shite Yobaremashita ga, Around 30 ni wa Muri na no de, hissori Book Café Hajimemashita

Summoned to another world by a talking orb that claims to be a god, Tsukina is informed that she must serve as its savior—tasked with restoring balance through her immense magical prowess, though the specifics remain vague. Now in her thirties, she initially declines, suggesting the role would be better suited to someone younger. Despite the existence of other summoned individuals already in that world, the orb insists on her involvement and offers to grant any wish in return. Tsukina seizes the opportunity, requesting the strongest protective magic and a function that allows her to summon any item simply by searching for it. With those powers secured, she abandons the hero's path entirely and instead establishes a quiet, secluded book café, determined to live at her own pace. This charming tale follows Tsukina, a single office worker in her thirties whose greatest joy has always been losing herself in a good book. When divine intervention drags her to a fantasy realm, she has no interest in epic quests or grand destinies. Settling into her new life, she channels her magic into crafting a cozy little book café, where her first customer turns out to be a handsome soldier who shares her passion for reading. Yet her peaceful retreat is disrupted when a fellow summoned "savior" begins stirring up trouble—forcing Tsukina to confront whether she can truly stay on the sidelines.
