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

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...

After their entire class was transported to another world, Yogiri Takatou and Tomochika Dannoura were abandoned when it was discovered they had failed to receive the Gift, a special power that the rest of their class inherited from a powerful Sage named Sion. What none of the others knew, however, was that Yogiri already had his own unique power — one that multiple world governments back home were keeping him under observation for: the power of Instant Death! With Yogiri’s abilities now exposed and being scrutinized by Sages and Swordmasters alike, this unlikely duo continues their adventure, determined to find a way back to Japan. The only lead they have to go on is to follow their former classmates’ trail and track down the formidable Sion in the hopes that she’ll be willing to negotiate. But even with the power of Instant Death on their side, the world around them seems intent on making the task as much of a hassle as possible!

After being summoned to another world, Yogiri and Tomochika were abandoned by their classmates as bait to distract a rampaging dragon. Thanks to Yogiri’s ability to cause instant death with a single thought, the two of them survived and made the arduous journey to reunite with their classmates in the capital city. Although they overcame tremendous danger along the way, rejoining the other students is still only the beginning. From the intricate schemes of the Sages Yogiri inadvertently made into his enemies, to being stalked by Ayaka Shinozaki, a synthetic classmate who acquired the power of a dragon and swore to take revenge on them all, to the machinations of Lute, the spawn of a monster Yogiri slew, who is now bent on releasing yet another Dark God imprisoned beneath the city, there is no shortage of people determined to kill them. Somehow, the unlikely duo must juggle these threats while attempting to draw out the Sage Sion in hopes of discovering how to make it back home.

Having overcome countless trials (without much difficulty), Yogiri and Tomochika finally managed to reunite with their classmates in the capital. But between the efforts of Ayaka, a synthetic classmate who swore revenge against her fellow students, the meddling of Sion, a Sage determined to cull the weak and produce a new superbeing from their class of candidates, and the revival of the Dark God Mana, the majority of the class — not to mention the entire capital — were ultimately wiped out. Somehow, amid the chaos, the unlikely pair were able to draw Sion out and acquire their first concrete clue about how to get home: they will need a number of Philosopher’s Stones, powerful artifacts carried within the bodies of the Sages. After taking one from Sion and finding another dropped into their laps by Risley, the only surviving clone of the Sage Lain, who they killed some time earlier, the two highschoolers set off in search of a third energy source, leaving a trail of ruins behind them.

With the majority of their class and the entire capital wiped out, Yogiri and Tomochika left behind the Kingdom of Manii in search of additional Philosopher’s Stones, the energy sources they were told to gather if they ever want to make it back home. Having received one stone from the Sage Sion, a second from Risley, and having taken a third from the self-styled War God Raiza, the pair next set their eyes on a new country in the east, following a lead on the potential location of another Sage. With the half-demons they were assisting now comfortably settled in the City of the War God, the two have left their previous companions behind to begin their journey home. But of course, nothing is ever simple. One after another, strange new people begin appearing in their path to block their progress, and some of their former companions may not yet be willing to let them go...

Leaving their growing entourage behind, Yogiri and Tomochika set sail on a cruise ship for the eastern island nation of Ent. But as always seems to be the case, things don't go quite as planned, and after attacks from pirates and the rebirth of an ancient High Wizard, they find their ship sinking with no land in sight. With the help of a mysterious ancient-dragon-turned-young-boy named Kouryu, they manage to escape the damaged vessel and just make it to shore in time. But as they continue on their journey to the Empire of Ent in search of the Sage Yoshifumi and the Philosopher's Stone he possesses, they are met with new obstacles as the twin goddesses Malna and Rilna finally begin to take measures to deal with Yogiri...sort of.

Having reached the island nation of Ent, Yogiri and Tomochika continued their pursuit of the Sage Yoshifumi and his Philosopher’s Stone, which led them into the Elven Forest. The forest proved to be more than meets the eye, however, as they discover that the space within it is warped and twisted, leaving them hopelessly lost with no clue as to how to escape. And while thanks to the machinations of a certain vulgar classmate they can hopefully say goodbye to the meddling of Malnarilna, it doesn’t take long before all sorts of other troublemakers start turning their attention towards the hapless pair, making their impossible journey through the Elven Forest even harder. And, wait, where did we leave those other three Philosopher’s Stones again...?

With their intense encounter with Yoshifumi behind them and yet another Philosopher’s Stone in hand, Yogiri and Tomochika begin making plans to leave the island of Ent in search of more Sages. However, with the acquisition of another Philosopher’s Stone, the infant they were carrying with them has now grown into a three-year-old. On top of reuniting with Vivian, Hanakawa, and many other friends they had thought long gone, there seems to be no shortage of interruptions to stop them from accomplishing their goal. And just in case that wasn’t enough, they discover they are now wanted—dead or alive—across the entire world, making their casual journey an even more challenging affair.

After retrieving a Philosopher’s Stone from the Sage Alice and collecting three more from Shigeto, Yogiri and his growing entourage finally make plans to put the events of Ent behind them and head for the continent in the East. Despite further setbacks, they manage to find a way off the island with the aid of the self-proclaimed goddess Hiruko. But it’s no easy task locating the next Sage on their list, and they discover that even getting into this new territory might be trickier than they first thought. Meanwhile, an ancient goddess awakens in the ruins of Ent’s capital and swears to take revenge on the world that dared to imprison her by exterminating all life, one person at a time.

Though Yogiri and Tomochika successfully managed to make their way to the mysterious continent of Belm, their success has come with a few drawbacks. As their companions are scattered across the continent, the duo (and their ghostly advisor, Mokomoko) soon find themselves caught up in the extensive warfare between Belm’s four factions. Yogiri’s abilities mean that they are safe from direct harm, but the bizarre system of laws governing the continent have left them in a position where even traveling around seems all but impossible. Somehow, they must find a way to reunite with their lost companions, find the Sage governing Belm, and retrieve his Philosopher’s Stone, all while dealing with the escalating response from the natives to Yogiri’s defensive powers. And wait—how did they get onto this island floating in the sky anyway?

With the vast majority of Luu’s powers restored and the UEG dead, Yogiri and Tomochika are on the verge of finally making it back home. However, in order to undo the damage wrought by the UEG’s rampage, the Great Sage resets the entire world to the moment Yogiri’s class was first summoned. While the people Yogiri killed remain dead, everyone else is brought back to life, including Sion, the Sage responsible for summoning his class in the first place. Having retained her memories of her previous encounter with Yogiri, she agrees to help him and Tomochika collect the Philosopher’s Stones once again. While things seem poised to go more smoothly this time with her assistance, it doesn’t take long for another Sage’s carelessness to throw the entire world into a brand new kind of chaos.

After the Great Sage resets the world, Yogiri and Tomochika are forced into Van’s new game in order to obtain the Philosopher’s Stones—their only lead for getting home now that Luu is gone. Although Yogiri can’t use his power without breaking the game, Tomochika’s combat prowess and the old friends they made along the way may be just enough to get them to the final boss. Everyone’s in for a surprise, however, when the Philosopher’s Stones start disappearing from the game...including the stones the party’s collected so far! To make matters worse, the Great Sage finally makes a move against Yogiri while they’re coming to grips with the missing stones!

Yogiri and Tomochika have made it through the game of Cavern Quest and now approach the last boss, “Lasbo.” Much to their surprise, Lasbo’s true identity is not that of a monster, but the other parties who’ve undertaken the same quest alongside them. Much to Van’ssurprise, the seven Philosopher’s Stones—keys to last boss’s area—have multiplied into hundreds, throwing the game’s conclusion into utter chaos. As he attempts to salvage what remains of his game, the Great Sage himself appears to observe the grand finale with his own eyes. Yogiri and Tomochika were hoping to finish Cavern Quest quickly in order to return to the surface and resume their search for a way home, but now that the Great Sage is involved, that’s going to be far more complicated than they ever imagined.

Now that they’ve successfully made it back home safe and sound, Yogiri, Tomochika, and the surviving members of their class begin the long work of readjusting to life in their own world. But even with their story finished, countless mysteries remain to be explored! This collection of short stories answers all sorts of questions left unanswered by the main series. What was Hanakawa’s previous adventure like? Who is Haruto Ootori, and why does he have wings? Just what has (the real) Enju been up to since we last saw her in the underground facility? There are plenty of answers to be found in over ten stories...and maybe another mystery or two to ponder!
