The God Below the Waves

Ren Kisaragi was a marine biologist, a man bound by logic, curiosity, and the fragile illusions of humanity. One deep-sea expedition changed everything: an accident in the ocean’s uncharted trench should have ended him, but instead, it marked the beginning of something far older and far crueler. He awakens in the crushing, lightless depths as a fragile squid—no longer human, no longer mortal, yet not fully beast. Alone in the Abyssal Realm, a world governed by ancient magic, unimaginable pressure, and the whispers of a sentient ocean, Ren’s body and mind are rewritten. Every kill, every consumed predator, every fragment of memory stolen fuels his evolution. The Abyss watches, hungry, patient, teaching him, testing him, bending him toward a purpose he cannot yet understand. As centuries pass, Ren grows beyond the limits of human thought and flesh. He absorbs the instincts, knowledge, and powers of leviathans, mutates under crushing pressure, and learns the forbidden magics of civilizations lost to time. With each transformation, the line between man and monster blurs—and the whispers in his mind grow louder, questioning his humanity, his identity, and his very will. But the Abyss is not merely a teacher. It hungers. It manipulates. And in its depths, nothing survives unchanged. Every predator hunted, every memory reclaimed, every fragment of power earned brings Ren closer to godhood—and madness. Now, the ocean itself stirs. Surface explorers begin to notice anomalies, while the descendants of the Old Sea Race stir in ruins deep below. Ren must decide: to remain tethered to the humanity he has lost, or embrace the Abyss completely, becoming a god of darkness, evolution, and dominion. In a world without light, where hunger teaches, fear guides, and evolution is the only law, only one question matters: Will he survive the Abyss—or will the Abyss consume him?

Naruto: I Died and Replaced Sakura?!

[December Release Schedule: 1-2 chapters from Mon-Thurs, 2-3 chapters Fri-Sun] UPDATES (12/14/25): * Holiday Special 3: Hatsuhinode no Konoha is released early! * Chūnin Single Elimination Tourney Arc finished UPDATES (12/13/25): * Training Month: final edits * Final Chūnin Tourney: final edits * Konoha Crush: final edits * Search for Tsunade: script revising * Reworked filler + movie content: script revising * Sasuke Retrieval: script revising * Next Holiday Special: final edits [Series Theme "インク・ステインド・ハート (Ink-Stained Heart)": https://www.youtube.com/watch?v=14obqoOTI-4] [Sylvie & ??????'s Theme "カラー・オブ・ヒズ・チャクラ (The Color of His Chakra)": https://youtu.be/hlbToS2ywYU] I died in the wrong forest and woke up in Konoha, in a body that finally felt like it fit. Last life, I was an anxious second-grader bleeding out under a rotting log, waiting for adults who weren’t coming. This life, I open my eyes in a hospital bed as “Sylvie” – no clan, no papers, just an orphan slot to be filled and a village that shrugs and moves on. Everyone writes me off as another stray… except one loud blond kid with whisker marks who decides I’m his first real friend. By the time Team 7 forms, I’m standing where Sakura should’ve been: the pink-trimmed kunoichi next to Naruto and Sasuke, pretending I belong there. I don’t get monster chakra, a secret bloodline, or a cheat-sheet of canon. What I get is stupidly precise chakra control, ink-stained hands, and this unnerving knack for feeling the “colors” of people’s bonds—love, grief, trauma, all the invisible threads tying them together. As I stumble my way into med-nin training under Tsunade, those threads turn into tools: I can anchor promises, steady someone on the edge of a panic spiral, and—eventually—try to hold a whole battlefield together with seals and stubbornness. The catch is that every mind I stitch back up leaves marks on me, and there’s a thin, ugly line between helping people heal and quietly rearranging them into something more “functional.” From the Land of Waves to the Chunin Exams, all the way to Akatsuki and the Fourth Shinobi War, I run beside Naruto and Sasuke through a world built on child soldiers and inherited pain, trying to nudge the script without breaking it. Somewhere between pranks, triage, and war councils, I get tangled up with a lazy genius named Shikamaru, a snakebit mentor named Anko, and the creeping fear that I’m not just saving people—I’m taking a seat that was never meant to be mine. This is still Naruto’s story about never giving up. It’s also mine: the boy who died in one forest, woke up as a girl in another, stole Sakura’s spot on Team 7, and decided nobody in this world was going to face their nightmares alone if she could help it. [OLDER UPDATES] [December 13th: Chūnin Single Elimination Tourney Arc finished] [December 11th: Forest of Death Arc finished] [December 7th: Holiday Special 2 ("Christmas" but not really, its the Rinne Festival but ya know) is released under auxiliary volumes early!
