The Heir of God of Time

Causality is influenced by how one event, process, state, or object contributes to the production of another event, process, state, or object where the cause is partly responsible for the effect, and the effect is partly dependent on the cause. Sanix Wilson, a normal high schooler, one day meets a mysterious girl who calls herself the Protector of Time. She asked him to be her Time Paradox to solve the unnecessary causality. To balance this unnecessary causality, the Time Travellers from the Time Travellers Agency of Krupticia are trained to prevent it from happening. Will he help her in her mission or else his life will remain as it is now as a high schooler?
