S1·E43 Run, yuu! Faster than a turtle!

When he gave her directions to meet in studio 606, Hayato Kidokoro never predicted that Yuu would misread the memo as studio 909 nor that Yuu would actually find it; if that is not enough, Yuu finds herself back 11 years in time to when Natsume was still gestating her. The Keeper of Time Balibali is overjoyed to have a visitor to interact with; Yuu's affinity for interactive demonstration rather than passive explanation becomes the preamble for all heck to break loose when Yuu emancipates the two time tortoises Piku and Dina which waste no time in wreaking havoc that gives birth to a strange new world borne from the past and future mixing with the present. After a »Get with the program!!!« scolding from Posi and Nega to take responsibility for fixing things, Yuu races off to search for Balibali but is forced to forsake learning the identity of the groom upon finding her future self as a bride because of the dire circumstances when Piku and Dina give chase after the pair not at all keen on having their fun spoiled. It ultimately takes a blast of magic at studio 909 before Yuu successfully subjugates the renegade reptiles and sets things right.
