How can the 'conquering hero' trope be developed in non - adult fanfic?

This is a translation. "Tang Yu traveled to an urban world of a light novel and became a rich second-generation villain. His only mission: to survive until the end of the plot to return to his world. He was doing fine, but unexpectedly, his internal thoughts began to be 'heard' by the female protagonists. Now they are all interested in him! Oh, he just wanted a quiet life and to survive until the end! Help!

Question: What would you do if you had omnipotent superpowers? To dominate the world? Or do whatever you want? Or maybe... Kamikawa Ren’s answer was that he wanted to be an ordinary person. As a creature with true superpowers, he always tries to be like ordinary people. During class, listen carefully to Mafuyu’s Sensei lecture like a normal student. After class, he patiently lectured the Nakano quintuplets about the topic like normal students. After school, like ordinary members, worked hard to help President Shinomiya solve her problems. After returning home, he friendly played games with Gabriel like normal friends. In this way, he has worked hard to become an ordinary person. However, what made him a little confused was, would the lives of ordinary people be the same as his?

What would you do If you were suddenly transported to the Nasuverse just before the Fourth Holy Grail War as a young Shirou with no access to a Magic Crest, Magecraft, or OP Servant?

[Daily updates are here! I'm committed to releasing 2 new chapters every day. Hope you enjoy the story!] [STRONG WARNING: MASSIVE HAREM!] [This novel features a protagonist who builds an extremely large harem, an approach to romance best described as 'catching them all.' If you dislike or are uncomfortable with stories that have massive harems and a protagonist with countless partners, I strongly advise you not to proceed. It's likely not the right read for you, so please don't feel obligated to continue.] [Inorin's Note - October 2, 2025] [Yahallo! This is Inorin. Please be aware that the quality of the initial chapters (1-20+) is currently quite low, and there is also a significant drop in translation quality with numerous errors in Chapters 160-190+. These chapters are pending revision. Until this message is updated or removed, the fixes have not been implemented. I apologize for the current quality and ask for your patience. Thank you!] ***** In a world reminiscent of comic books, an enigmatic traveler journeys through unusual landscapes and encounters the intriguing Yotsuya Miko, who senses the world's impending end. Concurrently, Yukino experiences an embarrassing incident while trying to call the police, which unexpectedly leads her to an invitation to join a mysterious "Doomsday Chat Group". This marks the beginning of their collective struggle against the apocalypse. As the narrative progresses, Hayasaka Ai confronts a formidable demon, while Eriri faces a terrifying evil spirit. Yukinoshita Yukino finds herself entangled in a perilous doomsday game, further intensifying the challenges for the group. The Doomsday Chat Group also welcomes a determined new member, March 7, who is resolved to save the world from its impending doom. Each member of the Doomsday Chat Group brings unique abilities and complexities. Able Angel can invoke divine power, exclaiming, "In the name of the Divine! Let the barrage begin! Overload mode!". Silver Wolf seeks refuge in gaming, often questioning hidden motives within the group. Nami desperately pleads for help, striving to survive, while Makima grapples with her identity and the enigmatic Ren Kazama, who casts doubt on the group's solidarity. The fiery outburst from Tushan Yaya further heightens the tension, revealing underlying conflicts. This Doomsday Chat Group is more than just a random assembly; it's a bond that will fundamentally alter their destinies. Filled with action, drama, and mystery, their journey promises unexpected twists and intense confrontations. Will they succeed in saving the world, or will the apocalypse spell the end of everything? ——————————————————————— Inorin Note: If you wish to support me so I can continue to survive and afford proper food, you can join my membership on Patreon [patreon.com/InorinTL].
