Toaru Majutsu no Index: Genesis Testament - Volume 4, Epilogue: That Human Returns – Science_Side,Interrupt.

A normal guy gets hit by a truck and isekai'd. Why? Because trucks are apparently some cosmic loophole. He decides to be a dungeon, because it sounds weird and interesting to be one. Is it? Let's find out.

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.”
