Chapter 31

"From Space..." (宇宙(そら)からの..., Sora kara no..., Tonari: 39 + 40) is the 31st chapter of the One-Punch Man manga series.

Part 1
A large craft is seen flying over A-City, where it stops and proceeds to destroy the entire city. Sky King is then seen, dead, his body falling apart as a large creature with several heads and wings comments to itself on killing the Sky King, and the destruction caused by the ship. Iaian, a hero, then crawls out of the rubble and witnesses the state of destruction of A-City, the only thing left standing is the Hero Association's headquarters. He then notices the giant ship above him, but only looks for a second before the large monster appears behind him and attempts to crush his head. The monster only crushes his helmet, its occupant having moved safely away. Iaian comments on how there would be no way he would not notice the monsters killing intent and then proceeds to attack it.

Part 2
Sitch is screaming, and after seeing that A-City was destroyed in an instant, he is certain the "earth is in danger" prophecy had come true. Bang asks Sitch why the Hero Association building is still standing, to which he is answered with the fact that Metal Knight had built it, and that it is much stronger than an average shelter, Metal Bat then notes that because it is built like a bomb shelter, the place has no windows. The heroes are preparing to leave to deal the threat outside, and just as Genos is about to ask Saitama to join them, he notices that his master is not there and that a hole in the "impenetrable fortress" ceiling has been made, apparently all the way to its roof.

Saitama is then seen on the roof, preparing to deal with the threat in front of him, a giant spaceship. Saitama leaps towards the spaceship and is shot with a colossal-size bullet, which he is able to dodge, and is also relieved, due to the fact that if the weapon was a laser beam, it would've burned off his clothes. Saitama is then once more shot with gigantic bullets, but repels them and sends them back to their own ship.

Meanwhile, Iaian is still fighting the alien Melzargard, who appears invulnerable to his attacks. The alien then retaliates and demolishes the area behind Iaian, as well as his arm. The alien then proceeds to split himself, into 5 different forms.
