One-Punch Man: Saving Fubuki from the Start

Transmigrating into the world of One-Punch Man.

At this point, Saitama hasn't joined the Hero Association yet.

City A is under attack by a Dragon-level monster.

The track-and-field girl and team captain Mizuki, Three-Section Staff Lily, Do-S, Tatsumaki...

Defeat the real Subterranean King!

When Boros's ship invades, led by the self-proclaimed leader of the Dark Matter Thieves, Lin Yu advises the Hero Association: "Launch a counterattack directly at the planet Boros is on."

Saitama: "Lin Yu made me realize that even the Serious Series is still far from enough."

Fubuki: "My psychic powers can affect an entire city, but Lin Yu's can easily cover the whole planet! No wonder he's a man I approve of! He's so powerful!"
