Saitama's Heroic Journey

...What can I say? I'll update whenever I feel like it...

Shishi: "Saitama is a hero, so anyone else can be one too. No one is a true hero. We're all human, and we have no obligation to sacrifice ourselves. But if no one else will protect them, then let us do it, because we want to be heroes!"

A punisher from across the stars, the strongest hero in reality, a former overlord of the universe, a reformed supervillain... Can this bizarre band of heroes save the universe?

Kaguya: "Um, can I quit?"

Thanos: "You can ask after you give me back my gauntlet..."

Boros: "Aren't you going to give me a new spaceship?"

China: "Can I bring Russia and Japan along...?"

Kratos: "I've got a bad feeling about this."

White Yaksha: "Same here!"

Asura: "As long as you don't make my daughter cry, you'll live!"

Doctor Manhattan: "Quantum trajectories suggest this event won't go smoothly."

Whitebeard: "Got any booze?"

Hyper Zetton: "Who knows if there's any!"

Shishi: "Come on, show some spirit! We have Saitama, don't we?"

Saitama: "...What are we even doing? I have groceries to buy."

Genos: "No matter how dangerous it gets, I will follow you, Sensei!"

The strongest hero in history and the most shameless hero in history team up to create the greatest body-swapping novel ever!
