Classmate wa Isekai de Yuusha ni Natta kedo, Ore dake Gendai Nihon ni Okizari ni Saremashita

On the cusp of summer vacation during their third year of middle school, Shuu Iori and his twenty-five classmates are abruptly yanked from their world by the goddess Ashera, who declares them chosen heroes destined to save a fantasy realm. While his peers are bestowed with incredible statuses, cheat skills, and an epic purpose, the summoning ritual proves imperfect. Unbeknownst to the goddess, Shuu had only just transferred into the class and is deemed an anomaly—left behind in Japan as the other twenty-five ascend to heroism. While his former classmates undergo rigorous training for an impending war in another world, Shuu remains in a peaceful, oblivious Japan. But he is not entirely powerless; he, too, received a status screen, though its functions are unclear. Spending his summer quietly and methodically experimenting with his skills, he finds small but meaningful ways to use his abilities, helping those around him in his daily life. His subtle experiments, however, do not go unnoticed. As Shuu continues his low-key investigation, the quiet life he clings to begins to fracture. Intelligence agencies and shadowy organizations around the globe take an interest in the student who was never supposed to be a hero, yet clearly wields power that cannot be ignored. What happens when a boy left behind becomes the world's most coveted secret—and its greatest unforeseen variable?
