  Summary

  From the creator of “Fuck It”.

  Hi guys, so I realized that a lot of materials from my fanfic is set in my creative universe of WTDSIK. Which can be a bit confusing, so I decided to make this as a collection of One Shot to clarify characters relations and their history.

  It can be read separately from “Fuck It”. As it’s just an exploration into Derkila and Iruma relations before the event in “Fuck It”.

  Summary

  Once the youngest Demon King, Iruma Suzuki suddenly awakens in his fourteen year-old body at Sullivan Manor, memories of his reign lost. The only clue being a cryptic voice from his ring, “Alikred”.

  As Iruma’s mana twists into something unfamiliar, he realizes: the past is changing, and he’s at the center of the mystery.

  Warning: NO BETA READER. Sorry for any misspelling as it’s a one person operation:/

  Short chapter, approximately 780 words per page. Can be more or less depending on my mood.

  Additional detail: Demon King Derkila is now unknowingly a father figure to feral child.
