Isekai Shoukan wa Nidome desu

In a world named Eclair, where conflict rages between humans, beastmen, and demons, a man is summoned to save it and fulfills his mission before returning to the human kingdom. There, he is betrayed by the king, fearing the hero's power, and sent back to the world as an infant through a magical transfer. Sixteen years later, he lives as Suzaki Setsu, a high school student who is often mocked for his bookish nature but continues searching for a way back to Eclair. He is unexpectedly summoned again by the human kingdom, this time with his classmates. He finds himself in Eclair five years after his last departure and reconnects with figures like the former demon king and beast king. Despite his lack of interest in conflict, he is repeatedly drawn into dangerous situations.
