Logos Codex

The Logos Codex (ロゴスコーデックス) is an ancient book that contains incantations allowing one to use the Spear of Anarchy.

History
Beta tasked Gamma with finding the Logos Codex at some point during the Delta Battle. However, due to Team Monolith's escapades involving their gathering of intel to win, Beta stranded Gamma in an alternate universe until Sigma's death. After Team Monolith's victory, Gamma revealed the Spear of Anarchy to Jasmine Keene and Hideki Iida. She used the manuscript and chanted the incantation, "B'khi-eel. Ah-ash-lem-tu-on. K'i-aheen. Kh'det bay-all-ma-ah", allowing her to kill "The One".

Since Gamma was not a deity and used the spear for an action of that magnitude, she was slowly incinerated, allowing Beta to grab ahold of the spear. Following this, Beta destroyed the Logos Codex, seemingly ensuring that only she knew how to use the spear. Unbeknownst to her, Hideki also knew the incantation after having a premonition of his death, via Jesus Christ.
