I'm Really Not the Lone Hero

When millions transmigrate together, who said I'd fight alone? Facing certain death, my stunning goddess master descends from the heavens, my sworn demon realm brother charges through the gates, a top-tier demoness from the beast realm arrives with fangs bared, and even that chubby ghost from the underworld shows up! One signal pierces the sky, and an army of allies answers the call. In a world where everyone's been isekai'd, I've got the ultimate backup—a multiversal crew ready to turn any battle into an unfair advantage!
