Ep 4. Double Booked / Gym Enemy Cricket

After a successful trip to the Floating Islands, Team Zenko Go is back in the city and ready for their next mission. However, they soon discover that they have double-booked their schedule and must figure out a way to complete both assignments at the same time.

Their first mission is to help a local library find a rare and valuable book that has been missing for years. The library staff is counting on the team to locate the book before a big fundraiser event the following day. The second mission is to investigate a string of break-ins at a local gym that has been causing a lot of damage.

The team splits up to tackle both missions separately. Yumi and Kazu head to the library while Hiro and Aria head to the gym. At the library, Yumi and Kazu use their ninja skills to search for the missing book, but their efforts turn up nothing. Meanwhile, at the gym, Hiro and Aria interview several witnesses, but nobody seems to have any information about the break-ins.

As time ticks away, the team realizes that they need to regroup and come up with a new plan. They decide to split up once again, but this time, they will work together on both missions. Yumi and Kazu will stay at the library while Hiro and Aria head back to the gym.

At the library, Yumi and Kazu search the stacks for the missing book while Hiro and Aria watch the gym from a nearby rooftop. Suddenly, they spot a strange figure climbing up the side of the gym building. The figure leaps onto the roof, and Hiro and Aria engage in a battle with the mysterious ninja.

Meanwhile, Yumi and Kazu find the missing book hidden behind a row of other books on one of the library's highest shelves. They quickly retrieve the book and prepare to leave, but they hear noises coming from outside the library. They peek out the window and see that the same ninja who attacked Hiro and Aria is now scaling the library walls.

Yumi and Kazu realize that the ninja must be after the rare book and prepare to defend it. Just as the ninja bursts through the window, Hiro and Aria burst through the door, having defeated their own ninja assailant. The team engages in a fierce battle with the two ninjas, but ultimately they are able to defeat them and recover both the rare book and other stolen items from the gym.

With both missions successfully completed, Team Zenko Go heads back to their headquarters to celebrate. However, they realize that they need to be more careful with their scheduling in the future to avoid double-booking their missions again.
