As a Legendary Costume, it can either be purchased with Rainbow Crystals at any time or obtained from a Costume Gacha pull.

Story
''Timekeeper Cookie once used to snip away countless timelines, but has now fallen into an irreversible feeling of futility. No matter what happens in the time rift, the Cookie only chuckles quietly, thinking it's all pointless, and flees the scene on the broken Sonic Embroider. Perhaps, this Cookie has seen too much...''

Pre-Pull

 * No point of trying. All Cookies are too small and weak...

General

 * Why change time? Because I can and it is fun.
 * The end justifies the means...!
 * What is the matter? Your problem was erased.
 * The TBD doesn't need to exist. Don't you agree?
 * It's just impossible for a Cookie to manage the time.
 * Whatever. I don't care anymore.
 * Fix the time? Why should I?
 * All I know are just little pieces of time...
 * How convenient it would be if there was only one future.
 * The future is changing this very moment.

Tired

 * No Cookie could handle it anyway...

Daily Gift

 * Use it if you ever escape the time pocket.

Tap

 * Why do we even need TBD? They're the ones ruining the time!
 * It's nice in this time pocket... Nothing ever changes here...­
 * It's too late to turn back...
 * Time pockets are where all forgotten times linger.
 * I'm not even the Director anymore!
 * So what if you have power? Just a Cookie. That's all.
 * I never used the key even when I was the Director. (Like hint)
 * Someone will help you get out eventually! But it won't be me. (Dislike hint)

Gift

 * I remember the time these were needed! (Given Royal Golden Dough)
 * There was once a Cookie who gave me the keys to the Director's office... (Given Bent Silver Key)
 * Looks like this old thing hasn't changed one bit! (Given Time Cog)
 * Gifts don't mean anything here. (Neutral)
 * You make me regret leaving that time pocket. (Given Rescue Certificate)

Trivia

 * Both Ruler of the Ephemeral Flow and Director of the TBD are the only two Costumes that are completely different characters. While other costumes are "what if?" situations for the Cookies, these two are Timekeeper Cookie and Croissant Cookie from a different timeline.
