Daa! Daa! Daa! Season 1 Episode 38 Ruu-kun Has Multiplied

Yayoi and Kanata are watching over Ruu while his mom and dad are visiting. However, while trying to impress him, Yayoi ends up creating a potion that accidentally multiplies Ruu! The house is soon overrun with Ruu clones, making it difficult for anyone to get any work done. To make matters worse, all the Ruu clones begin to act like little rascals, causing chaos wherever they go!

Kanata suggests that they try to reverse the effect by creating another potion, but Yayoi cannot remember the recipe, so they have to resort to trial-and-error. Meanwhile, Ruu's clones continue to wreak havoc, which leads to even more chaos in the house. With each failed attempt, Yayoi becomes more and more frustrated, but Kanata encourages her to keep trying until they find the right formula.

The situation gets even more complicated when the group has to leave the house for a bit, accidentally leaving some of the Ruu clones behind. When they return, they find that the clones have escaped and are now wandering around the town, causing mayhem wherever they go. The group splits up to try and find and collect as many of the clones as possible, but it's not an easy task.

As the day goes on, the group manages to round up most of the clones, but they still haven't found the original Ruu. They eventually find him at a playground, the only one who hasn't multiplied. Ruu reveals that he didn't eat any of Yayoi's potion, which is what caused all the clones. Instead, he had been sneaking around the lab and had already taken a concoction that was designed to make him grow bigger.

Relieved, the group returns home with the original Ruu, and Yayoi finally remembers the correct ingredients for the potion that will reverse the cloning effect. She was able to quickly make the potion and administer it to the clones, which caused them to merge back into the original Ruu. The day ends with Yayoi and Kanata reflecting on their adventure and how they were able to overcome the challenge of multiplying Ruu, turning a potentially disastrous situation into a fun and memorable day.
