Summoned to Another World... Again?!

異世界召喚は二度目です

Setsu Suzaki once saved the world of Eclair as a summoned hero, only to be betrayed by a fearful king and reborn as an infant back on modern Earth. Sixteen years later, mocked at school as the gloomy boy always buried in a book, he is yanked into Eclair a second time, now dragged along with his entire class. With the powers and memories of his past life intact, Setsu navigates a return that no one else around him understands, reuniting with old allies while shielding his unsuspecting classmates.
