Toaru Majutsu no Index: Genesis Testament - Volume 1, Chapter 4: Interaction with Another World, the Starting Point — “R&C OCCULTICS Co.Ltd.”

18 years have passed since I was born as Allen, the eldest son of an earl in this world, while still retaining my memories of the present world. This world is peaceful and a stable society. The only extraordinary thing is that I was reincarnated into a world that is lenient on the existence of concubines. I selected a silver-haired maid as a sex slave and second wife candidate from among 10 candidates after a strict fellatio practical exam. I then lived an erotic life at home and at school as an attendant, but my reincarnated life is so fulfilling that I'm worried it will explode, as my busty childhood friend, a noble girl who was unsuccessful, ran for the third wife candidate, and my stepmother, who was my virgin partner, was sold off.

Eighteen. The age of Awakening. An important moment where every human in the desolate maga-cities unlocks their Talent, a unique ability to carve a path in this monster-plagued apocalyptic world. Alister Hazenworth, a graduating student, and a rising star at the prestigious Aegis Academy, was destined for greatness. His exceptional athleticism and magical aptitude promise a powerful Talent – a guarantee for a secure life and social status.But fate had different plans. During Alister's Awakening ceremony, it's revealed that he's a Summoner. Instead of admiration, he faces mockery. His once bright future turns bleak as his “friends” desert him for Talents they see as more “useful.”left alone, Alister awakens a system.[Host found, system binding...][System binded successfully.][Congrats, you have gain the status of 'player'.][Ding!! Congrats to the player for awakening The Dragonforge - an overlord system.][Ding!! it has been detected that the player possesses a latent draconic aspect, and as such will only be able to summon dragons!!][Will the player like to proceed with their first summoning?]Cast aside and underestimated, Alister becomes a force to be reckoned with. He embarks on a journey, building his own dragon army – a crew of majestic wyverns, fearsome drakes, and ancient wyrms. He raids the wastelands, reclaims lost resources, and dismantles the prejudice against summoners. Every day, his power grows, his bond with his dragons deepens, and his legend spreads like wildfire.

Humanity has been gradually transported to the Abyss by a bored god to compete against other races and monsters.The problem is… humanity failed. In a last desperate push the strongest survivors chose a comrade to travel as far as possible back in time.

Life used to be so simple,

Full of false hope and endless beliefs in one’s ability in wooing that beautiful girl.

But in a single instant,

Everything as you knew it, plummeted faster than a spoken rejection.

What is real and false can’t be determined,

As the world slowly falls into the maws of the apocalypse.

How will our simple friend respond to the call; the summons?

No matter what he chooses,

Chaos SHALL Reign!
