Summoned to Another World for a Second Time

Once, a man was summoned to a foreign world and, through his valor, saved it. His feats made him incredibly popular, turning him into an isekai-normie—a celebrity in exile. Yet a devious trap dragged him back to his own world, and he must begin anew as a baby. This is the chronicle of a wildly exceptional ex-hero who lived as a brooding high-schooler, only to be summoned again to the very same other world in an unforeseen twist.
