My F-Tier Titan Is a God System

Jack Vance travels to The Titan Era. Rifts opened, demonic beasts ran rampant. Humanity resists by awakening Titans. Jack awakens an F-Tier "Tower of the Ten Fiends" during the ceremony. Mocked as "trash", he faces expulsion. This Tower is a forbidden divine object sealing ten god-tier fiends, bound to a Divine Choice System.
