The Regressor's Notepad

As he lay dying, Sion cursed his ability, 'Notepad,' as utterly worthless—nothing more than a passive recorder that couldn't even save him from House Libra's blade. But with his regression comes a dramatic amplification of his power, transforming the Notepad into a tool that can store, organize, and perfectly recall memories from his past life. Now armed with the foreknowledge of his enemies, Sion vows to infiltrate House Libra as their guardian knight and record every step of their ruin from within.
