Synopsis: An Otherworldly Summoner Unrivaled in the Modern World Against Mythical Monsters ~The Love of the Strongest Summoned Beasts Who Made a Contract With Me Is Too Strong

Reima, a Summoner, was transported to another world where he defeated the Demon King and became a hero of the people.

Bidding a silent farewell in his heart to the summoned beasts who fought at his side, he thought his life had ended... yet he awoke in a hospital in a parallel Japan? It's just like his original world, but now there's dungeons to be explored and monsters on the loose. Strangest of all, his summoned beasts are still with him! "I'm relieved that I get to see my summoned beasts again but it seems their love is heavier than before...?"
