In the 30th century, Tyler Rustel is an eccentric and visionary genius, renowned as a brilliant inventor. His life, however, comes to an abrupt end when a small experimental nuclear reactor explodes in a series of unforeseen events. Yet, death is not the end for Tyler. He awakens in a body that feels both familiar and foreign—a parallel version of himself in a completely different universe.This is not a world of technological progress or orderly civilization. Here, twisted gods roam the cosmos, shaping realities according to their cruel whims. The moral laws that governed his previous world do not exist. This is a magical universe, one marked by brutal betrayals, interdimensional wars, and endless massacres. The balance between the forces that rule this cosmos is fragile, and Tyler finds himself at the center of schemes involving powerful entities and boundless ambitions.However, Tyler is no longer an ordinary man. Upon awakening in this new world, he discovers that a fragment of his technology has survived with him: an advanced artificial intelligence system capable of analyzing, adapting, and enhancing anything, provided it has the necessary data. From magical weapons and arcane spells to alchemical techniques and enchanted jewelry, everything can be optimized under his supervision.Armed with this technological advantage in a universe dominated by magic, Tyler quickly realizes the potential of his unique position. While others struggle to survive, he schemes to conquer. Driven by his sharp intellect and a questionable sense of morality, Tyler embarks on a ruthless campaign to achieve magical supremacy and subjugate all worlds around him. He seeks neither redemption nor alliances. His ambition is clear: to rule everything and everyone as a tyrant, to amass an immense harem of women, and to father one million children to establish his legacy across all realms.

In this world, there are those that are fortunate and those who are not.

Ethan Bellrose is neither; he is cursed. At nineteen, he has lived his entire life sheltered in his home as his fragile body blisters under sunlight, breaks under the slightest impact, and falls to any sickness.

However, the arrival of a world-changing digital service catches the hopeless young man’s eye: “Reincarnation Online”--a virtual reality experience that gives a new fantastical life to those who are unfulfilled with their current path.

For Ethan Bellrose, the choice is simple. Without hesitation, he orders the virtual reality headgear, choosing to abandon his current life and live forevermore in the world of fantasy, magic, and endless adventure–”Arcadius.”

Though what he finds is a world not full of leisure and trivial triumph, but a world just as alive and full of darkness, glory, and grandeur as Earth–if not greater.

Starting from square one as an infant, given a new name and family, this is the eventful life, full of dreadful lows and exhilarating highs, of “Emilio Dragonheart.”

High-school student Koremitsu Akagi finds himself attending the funeral of Hikaru Mikado, who had died in an accident during Golden Week. He’s not sure why he’s there, as he only exchanged a few words with Hikaru at school. However, Hikaru doesn’t seem to be completely gone from the world, as he comes back as a ghost in order to fulfill a promise to Aoi Saotome, his fiancée. Since Koremitsu is the only one who can see him, he asks him to carry out his promise in his place.

Complying with his request, Koremitsu tries to fulfill Hikaru’s promises to the rest of his “girlfriends”, helping them overcome past misunderstandings and repair broken relationships.
