    Summary

    This work is simply a creative writing project for myself based around the ongoing Reddit CYOA Weekly Waifu and Parks Catalogue found here.
    https://www.reddit.com/r/nsfwcyoa/comments/1jv079h/weekly_waifu_perks_catalogue_updated_archive/
    This isn't beta read. This isn't especially well put together. This is primarily posted for ease of reading for myself and the small handful of friends who want to read my nonsense. For anyone else who happens to enjoy it I'm glad. As I'm primarily writing for myself suggestions are welcome but expectations are not. It updates when it updates and contains whatever I want. Enjoy.

    Summary

    After dying in his mundane life, Hikari Akatsuki is reincarnated into the chaotic world of High School DxD—starting as a powerless human caught in the battles between devils, angels, and dragons. But everything changes when he awakens [Dimensional Gate], a god-tier skill that allows him to bend time, warp dimensions, and leap across multiverses.

    From a struggling underdog in the DxD world, he ascends through battles, gains allies (and lovers), and becomes a force feared across all realities. His journey takes him beyond the DxD realm—crossing into universes inspired by Fate, Bleach, Tensura, and more—building an empire while uncovering a cosmic truth: his reincarnation wasn’t a mistake, but a second chance for something far greater.
