What Happened to the Betrayed Hero After That...

A high school student summoned from Earth who became a hero is betrayed by his companions in the midst of battle against the Demon King—and by none other than the princess known as the Holy Maiden. What path will the surviving hero and the Demon King take? What does the traitorous Holy Maiden want to do? What about the other companions? The protagonist, no longer a hero but returned to being just a high school student, realizes he didn't know this world. People wounded in conflicts between nations, persecuted demi-human races. Learning of the existence of gods and his own fate, what does the former hero think and what will he do? This is the story of what comes after for a hero betrayed by his allies. (The protagonist's name has been changed from Sakuramachi Mikuro to Shiina Issei.)
