Saikyou Yuusha Party wa Ai ga Shiritai

Buildings crumble. Chaos erupts in the streets. And in the middle of it all, the strongest hero throws himself into the line of fire bracing an attack meant for someone else, close enough to feel their heartbeat. Some heroes fight for glory. This one keeps ending up in someone's arms instead. The world has already been saved... perhaps a little too well. Thanks to the strongest Hero Party in history, not only has the Demon King been defeated, but wars have ended, racial conflicts have vanished, cities have made peace, medicine has advanced, education has flourished... and just about every problem imaginable has already been solved. Unfortunately, that leaves one group with nothing left to do: the other heroes summoned from another world. Robbed of their destiny, these aimless heroes have gone completely off the rails. From hopeless romantics with impossible dreams to eccentric oddballs with the strangest obsessions, they're less "heroes" and more walking disasters. Strongest Hero, please save the world... from its own saviors! (Source: Crossed Hearts)
