Short stories about Issei and his harem. Follow along as each member of Issei's harem gets a chapter dedicated to them! Each tale leads to a secret mystery revealed at the end of the book. Everything is told in one timeline. Updates are once a week on Sunday! (English is not my first language. Grammarly is used for grammar and spelling.)

Knull, a name that struck fear into the hearts of the strongest gods and beings of the supernatural. His power's that rivaled Shivas and Indra's. The slayer of the Sky Dragon's makes his return through the blood of a newly birthed devil. Issei will wield the Necrosword sword and have the powers of Knull. This book will have a darker version of Issei but not crazy dark.

Hyoudou Issei should have died the night he was betrayed. Instead, he awakens as a Shared Piece Devil, bound to three masters-Rias Gremory, Sona Sitri, and Sairaorg Bael(Valeria Bael)-and wielding a Sacred Gear that should not exist. Absolute Causation is not power or magic. It is a law. Every meaningful action creates an unavoidable effect, converted into Causation Points beyond mana, fate, or divine control. With the Boosted Gear awakening alongside it, Issei enters a world of Rating Games, devil politics, and supernatural wars-where strength can be challenged, fate can be resisted, but causation always collects its due.
