Honkai: Star Rail: The Defier of the End's Abyss

(One heroine: March 7th; a few original plot details) (I’m a new author, so some characters may be OOC. Please forgive me if the writing isn’t great.) (The following is something I made up.) Ling Yunfeng was an ordinary person ground down by life until he felt numb. He was a huge fan of March 7th from Honkai: Star Rail, and she had become the only light in his life. He watched her adventures and that innocent, adorable smile that seemed capable of healing anything. “I really wish I could meet you…” By a stroke of bad luck, Ling Yunfeng transmigrated into the world of Honkai: Star Rail. He merged with the divine body of [Nihility], and [Nihility] affected his memories and senses, turning him into a Self-Annihilator. As for why he wasn’t erased by [Nihility]… It was because of the deepest obsession one person could hold for another. When he once again set out on his journey as a lost traveler, when he finally met the person he had longed to see day and night… Would [Nihility] plunge him into the abyss once more, or would his [obsession] overcome the corruption of Nihility? “[Nihility] once enveloped me. I wasn’t afraid, because I knew that no matter what, I would never forget her…” “I’ll find her, all the way to…the end of this journey.”
