From brewing whiskey out of car tires to brewing immortal potions just because they are tasty.Regressed from a world where the only issue technology failed to solve was boredom, Theo, an adept nanomancer and master brewer, finds himself in the literal shoes of magic academy's trash teacher.Cultivation? Magic? Martial arts? Craftsmanship?No.Now is the time for this world's first Nanomancer to rise and establish alchemy as the fifth great subject for others to follow!

In a world yearning for grand adventure, a soul, weary of mundane existence, is ripped from his reality and thrust into the nascent era of One Piece.Reborn as Dracula D. Alucard, he finds himself in a surprisingly tranquil time, a quiet before the storm of the Great Pirate Era. But within him, a chilling truth awakens: an unyielding immortality.His mere presence shatters the calm, birthing the terrifying legend of an unkillable monster.Even Gol D. Roger, the soon-to-be Pirate King, is left in bewildered disbelief: “I don't understand; that sword thrust clearly hit his vitals.”The mighty Whitebeard acknowledges a new horror: “That man is a monster even harder to kill than Kaido!”The World Government, driven to utter despair, can only lament: “We've assassinated him successfully thousands of times. Why is he still alive?!”And the legendary Marine Hero, Garp, simply quips, “Kaido? I think that guy killed him...”For Alucard, however, this endless defiance of death is merely a perplexing fact, or perhaps, a casual game.“What's the big deal?” he asks, a faint, almost innocent tilt to his head, as if genuinely puzzled by their consternation. “Killing me is simple. Just stab my heart about eight million more times.”As the world stands on the precipice of an age of grand dreams and unfettered ambition, what fate awaits the eternal devil who cannot die, doomed to wander a sea that promises everything but an end?
