From Space...

From Space... (宇宙(そら)からの..., Sora kara no...) is the thirty-first chapter of the One-Punch Man manga series.

Part 1
A large craft is seen flying over A-City, where it stops an 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 it's 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 into their own ship.

Meanwhile, Iaian is still fighting the alien Melzalgald, 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, which are all cut by Atomic Samurai, who was worried for his disciple and even noticed the lost of Iaian's arm. Iaian then warns his master of the danger behind, while the alien bodies behind him reassemble and begin to attack. Atomic Samurai then slashes the alien fiend many times, and proceeds to tell Iaian to stop his bleeding. The alien then reassembles itself once more, this time into single body with only one head. Bang and Metal Bat then show up to help defeating the monster, and while it is distracted, Puri-Puri-Prisoner shows up from behind and attacks it as well, remembering the words of the Sea King and attacking with no remorse.

On top of the association building. Child Emperor is wondering how the heroes are supposed to reach the spaceship, and Superalloy Darkshine even proceeds to the "Strongest Man On Earth" King, who tells them there is nothing he can do and that they should just wait for Metal Knight. Said statement angers Tatsumaki, causing her to ridicule King, claiming that she shall do it herself. Genos offers his help to Tatsumaki, but she turns him down claiming she already said she'd do it herself, all the while Superalloy Darkshine tells him if he angers those who are considered "stronger than them", he will get killed. Genos is then shown confident, for Saitama has already gone ahead into the enemy ship.

On the ship, Saitama is confronted by Groribas, who he then swiftly kills. Saitama however is still a bit bothered, as he destroyed quite a bit and defeated many soldiers, but the ship does not fall and the leader may have not shown his face yet. At another place in the ship, the alien Geryuganshoop is monitoring Saitama, worrying as was capable of killing Groribas, one of their best, wondering of how the intruder even got in and why the guard Melzalgald hasn't stopped him. Geryuganshoop is then approached by the ship leader Lord Boros, Geryuganshoop then proceeds to tell his boss of the damage done by the intruder. Lord Boros reveals that the ship will only fall if the power sphere is destroyed, and tells Geryuganshoop that since lesser warriors have no effect on the intruder, that he shall call Melzalgald and Groribas and all three shall face the intruder. Geryuganshoop tells Lord Boros that Groribas has already been defeated, but that he has no reason to fret for he shall call Melzalgald and the two of them shall face and beat the intruder, hearing of the intruder's great feat, Lord Boros takes an interest in him.

The fight on the ground continues, with Melzalgald about to attack Puri-Puri-Prisoner, and Bang jumping in to intercept and counter. Melzalgald then decides to call the ship to fire their cannons for support, and even dispatches one head to do so, the dispatched head is then chased and hit by Metal Bat. The main body of Melzalgald then is contacted by Geryuganshoop who tells him there is an intruder on board the ship.
