( Hey guys!!!! The events in this book is partially cannon, since these events will only occur in the "Bad Ending" and it is not comfirmed which ending is gonna occurs yet) In the bad ending, the previous time god knew it will be destroyed soon. So it organized some oddly specific events, so that another being will obtain the ability to manipulate time. And that previous time god can finally retire, but everyone needs time to learn. So the previous time god decided to tutor the next time god until it knows what to do, and tell the next time god how to use its powers.
