The much older Timedyne, who came from a much far future than the young Najimu's time, arrived in the the present time just when Pietro got defeated by Don. Timedyne successfully captured Tocky's partner Ticky, but just as he is going back to his time using the time portal, Katsu intervenes and accidentally send the taiko drum and Ticky into other time, losing Ticky in the process. Having no choice, Timedyne and his gang use the time portal in order to find Ticky, who is now split into several parts during the time-travel, with Ticky's Timestone being transported to young Najimu's time where the young Najimu found it.
From then on, Timedyne and his gang time-travels to various eras to tries to find Ticky's parts, only to have Don and his co. found the parts before they did again and again. Eventually, Timedyne realize that as Ticky was split into several parts, he can only just grab the last parts, which is Ticky's Timestone, and Timedyne think that it is time for him to change the past.
Meanwhile, Don and co. arrived in young Najimu's time, and met up with the young Najimu, who is unaware of his older self's doing up until the two met. However, Najimu got tricked by the older Timedyne and is transported to Timedyne's base in the far futrue time by his older self. He had the timestone stolen by his older self and is hold captive there until he is rescued. Najimu joins up with Don and co. and goes to the deepest of the base and fight against his older self, who is now has two Timestones in his own hands. Having overwhelmed by Don and co. and his younger self, the older Timedyne had no choice but to fuse with the two Timestones and power up, but is then defeated in the end.
With the Timestones unfused from the older Timedyne, the young Najimu quickly grab one of the Timestones and return it to Ticky and thus Ticky is whole again. The older Timedyne tries to retaliate, but just as he try to, his own Timestone suddenly disappeared! It was from there that the young Najimu learned from Don's allies, as well as his older self, that his mother Sara is currently suffering from a life-threatening disease that would eventually take her life. Having learned the truth behind his older self's motive behind his action, Najimu decided that, even without the Timestones, he will change his mother's fate by becoming a doctor to save her life, much to his older self's surprise. The older Timedyne then realized that it is not the Timestones that can change the history, but the people's heart.
After everything had came to an end, both Najimu and his older self, as well as the Timedyne gang and Don's allies from various eras, time-traveled to the present time and enjoying the summer festival event there. With everyone and his younger self returned to their respective time through a time portal opened by Ticky, Timedyne return to his own time, but before he can, something unexpected happened; Much to everyone's surprise, a much older, wheelchaired Sara came out of the time portal. It turns out that Timedyne's younger self had change his past thanks to the young self's decision to became a doctor after everything went through. Bidding farewell to Don, Katsu, Tacky and Ticky, Timedyne returns to his own time with his mother.
