My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me! —AΩ—

Awaking to absolute chaos and carnage while on a school trip, Yogiri Takatou discovers that everyone in his class has been transported to another world! He had somehow managed to sleep through the entire ordeal himself, missing out on the Gift — powers bestowed upon the others by a mysterious Sage who appeared to transport them. Even worse, he and another classmate were ruthlessly abandoned by their friends, left as bait to distract a nearby dragon. Although not terribly bothered by the thought of dying, he reluctantly decides to protect his lone companion. After all, a lowly Level 1000 monster doesn't stand a chance against his secret power to invoke Instant Death with a single thought! If he can stay awake long enough to bother using it, that is...

Transported to another world and abandoned by their friends as bait for a nearby dragon, Yogiri Takatou and Tomochika Dannoura manage to survive thanks to Yogiri’s power to invoke Instant Death at will. Despite having been abandoned by them, the pair decide that their best option for making it in this world is to reunite with their classmates, and they set off after them. After a few close encounters in the city of Quenza and on the train taking them onwards, the two manage to reach the city of Hanabusa, a place that seems to mirror modern Japan. They decide to wait there for the rest of their class to catch up but come across a rogue classmate who has already reached level 10,000 and seems dangerously close to world domination!

Having dealt with the threat of rogue classmate Yuuki Tachibana, Yogiri and Tomochika find that things are only getting worse. Their previous adventures have drawn the attention of the Sage Lain, and it didn’t take long for her subordinates to track them to Hanabusa, where they had intended to reunite with the rest of their class. Between the Sage’s minions and the arrival of a new Aggressor, it seems their luxurious stay in the city is coming to an abrupt end. As the landscape around them is transformed into a post-apocalyptic nightmare, the two are forced to realize that reuniting with their class may be a lot more difficult than they had first imagined...

With the events of Hanabusa behind them,Yogiri and Tomochika’s journey to the capital has brought them deep into the wilderness of the Garula Canyon, where they meet an enigmatic man known only as the Swordmaster. In hopes of finding any information that might help them get home, the two reluctantly decide to participate in the trial unfolding there: a selection process for those wishing to become Knights of the Divine King. But when Yogiri slips up and accidentally uses his power to kill someone central to the history of the world, their objective quickly changes to escaping the tower where the trial is being held before anyone realizes what he’s done.

Yogiri and Tomochika continue on their way through the Tower of the Trial in hopes of escaping before it comes to light that Yogiri has not only killed the Dark God, but has also started to do significant damage to the tower itself. The other participants are not so understanding, however, and seem determined to stop the two high schoolers at every turn. At the same time, the Sage Aoi follows Yogiri and Tomochika’s tracks to the tower just in time to witness the arrival of an infamous Aggressor known as the Hedgehog. As ever more supernatural beings converge on the swordmaster’s trial, it becomes clear that getting to the capital will be even more of a chore than Yogiri and Tomochika had imagined.

Having finally made it out of the tower, Yogiri and Tomochika are greeted with an apocalyptic scene—or at least, it would have been, if not for Yogiri accidentally killing the Dark God who’d been trapped there. Despite the flawless execution of the goddess Vahanato’s plans, they amounted to nothing more than releasing her lover’s corpse from its imprisonment. After a quick visit from the Hedgehog and brief encounter with the Dark God’s surviving spawn, Yogiri and Tomochika are finally able to resume their journey to the capital. Meanwhile, with the disappearance of yet another Sage, Sion is finally beginning to realize just how much of a threat Yogiri is to their world.

With the events of the tower behind them, Yogiri and Tomochika begin making their way through the Meld Plains, a foggy expanse of crystalline plants and animals, towards the capital, in hopes of reuniting with the classmates who left them for dead on the bus. After dealing with a short distraction on the plains, they manage to make it to the city but find that getting permission to enter may be a bit more complicated than they had first hoped. Meanwhile, another member of the class who had been abandoned wakes up in the ruins of their tour bus. Disoriented and critically wounded, she finds she is not quite as alone as she thought, and Yogiri left behind just the thing she needs to treat her wounds.
