Toaru Majutsu no Index - Volume 4, Chapter 1: Hex Suspect of the Magician World.

“Obtaining the topmost degree of talent in sword arts in the world requires giving up 72 years of lifespan, which leaves you with only five more years of your life. At the same time, you will never be able to feel love, kinship, and friendship, and you’ll end up leading a lonely life until your death, unable to procreate, or to have any descendants.

“From now onwards, everything related to happiness in the human world shall no longer be of your concern. Are you willing to accept this?”

“Hahahaha, I’m already alone bereft of all support, my hopes dashed to pieces, shouldering only absolutely irreconcilable grudge and hatred, why would I disagree? Why would I not want it? I couldn’t ask for anything better!!”

His sword sweeps across the Divine Continent for seven days and nights, moving 90,000 miles through the starry skies, unhindered.

He slays saints and buddhas in Heaven, slaughters demons and devils in Hell, sweeping away all the grievances in his heart.

Beatty, a weak squirrel shapeshifter who was born into a lion family. Because of that, I lived my life being ab*sed at my aunt’s house in the Capital. When I told my only friend and fiancé, the Second Prince, that I would leave to achieve my dream, ‘Ritter, you bastard…!’ I died on his fangs. I opened my eyes again to my childhood, the time before I got myself involved with the Second Prince. At times like this, what do you need? Speed. I immediately withdrew my body only and ran away to the territory of my biological father, the Lion Duke. Though I won’t be welcomed, if I possess this one great secret that will only be discovered in the future, I won’t get kicked ou— “Welcome, Young Miss!” “OMG! When did you grow up like this…?” “Young Miss is walking with those two cute feet!” … Huh? Why am I welcomed like this? No way, is that my statue?

A fourth chance at life. The last chance.Zarek remembered when he first experienced the Godsfall Apocalypse. Those tears of red and sparkling rouge that split the skies, opening up one dangerous realm after another.That feeling of helplessness had been palpable, heavy... suffocating. It hung above his head like a guillotine, an edge graced by death's kiss...He grinned at it.One last ride, no Talents left on his stat screen, and nothing but a dull machete and his girl by his side. What was a better thrill than that?How could he possibly fail a fourth time?Unfortunately, there were others. Other Rebirthers. Some that might have been on their last attempt just like him, or some that still had more to give to this cruel world.None of it mattered, though. He had planned everything out meticulously, each life playing its own role.He would come out on top this time. How could he not?He was Zarek Ashborn.

Michael was suddenly reborn into a another world by a God because of an accidental death. To make up for this fact, the God gave him another life in a fantasy world of swords, magic, and monsters.Unfortunately, it turned out that the world he was reborn into was still stuck in the medieval times. It didn't have electricity, it didn't have proper plumbing, and it didn't have any technology that he was so used to back in his old world.But thanks to the God's blessing and an AI assistant called ChatJK1, he was given the power to MAKE his life comfortable. Slowly, Michael transforms this new world into a place even better than his previous one by taking ideas from the modern world and putting it in this world, with the added bonus of magic.
