Breaking Into Another World: I Will Save My Sister!

Jack Saunders and Anna Saunders were ordinary siblings bound by a shared passion for Japanese culture and anime. Their trip to Akihabara, the bustling hub of Tokyo's otaku culture, took an ominous turn when a mysterious magic circle emerged, ensnaring Anna within its confines. Jack, desperate to rescue her, exerted every effort to breach the barrier, but to no avail. Powerless, he watched in torment as the summoning spell whisked his sister away. However, this was not the end. Upon discovering that people were being summoned at regular intervals, Jack realized that breaking the summoning spell’s barrier could transport him to the same world and reunite him with Anna. Despite the daunting challenge and the strain on his sanity, Jack threw himself into relentless study and research. He explored every scientific discipline conceivable, seeking a method to predict and disrupt the summoning circle. Two decades later, Jack succeeded. Equipped with cutting-edge technology, full-body augmentation, and advanced AI integrated into his brain, he finally breached into the fantasy world. The challenges awaiting him were far greater than anticipated. The threat of a demon invasion loomed large, and corruption plagued humanity. As for the so-called summoned heroes? They were part of a grand deception. Thus, Jack knew he had to grow stronger—and fast! This is the tale of Jack Saunders, of his relentless journey, of his struggle against overwhelming odds to reunite with Anna. ------------------- I've read and watched countless isekai where the protagonist's past life is depicted as a loser or a failure. So, I thought, why not create a protagonist who is strong and successful? Why not have him forcefully enter another world instead of being passively transported there? Why not prepare him with everything possible before entering the other world? Thus, this is my attempt at writing an isekai story where the protagonist's life on Earth truly matters, where there is a clear goal set even before the story begins. Of course, it will still be filled with the anime and isekai clichés I love. Especially the beginning, inspired by The Rising of the Shield Hero, which can be dark and disturbing. So, expect: - A powerful Canadian big brother protective of his little sister. - NO incest. (Yes, I stand by my words. The little sister needs protection, not lewdness.) --------------------------- Updated daily R-18 tag is for dark and gore content.
