Several generations after the original Yatterman series, Leopard lives with her mother and guardians, Dorothy, Voltkatze, and Elephantus, just outside the prosperous Yatter Kingdom. She lives a happy if impoverished life, unaware of her ancestral ties to the infamous Doronbow Gang, until she discovers a mural of Doronjo, Boyacky, and Tonzura in a sealed off area of her home. It turns out that Dorothy, Voltkatze, and Elephantus are descendants of the villainous gangsters, which is why they have been forbidden from entering the hero Yatterman's Kingdom! At first, Leopard vows to never engage in villainous actions like her ancestors, but new circumstances may mean that she must go back on her word, donning the identity of villain in search of true justice.

Life hasn't been fair to Koyomi Morishita. Even though she's in high school, she's so short that everyone assumes she's still in grade school. The boys and girls in her school tease her mercilessly, and she's not exactly graceful either. On the other hand, she's still better off than Yumiko, who has a magician trying to kill her. Or at least Koyomi was until their paths crossed! Fortunately, salvation arrives in the form of master mage and graduate student Misa Anehara, who agrees to take Koyomi under her wing in learning the new style of magic, which breaks enchantment down into sequences of code. That'll be quite a task, given that so far Koyomi's talent seems to consist of making washbasins randomly fall out of the sky. But if it was easy, it wouldn't be magic, would it?

Second Youkai Watch movie.

Primary school student Keita Amano's curiosity is as innocent as any other child's his age. But when one day he decides to venture deeper into the forest, he encounters a small and mysterious capsule. Out from its depths comes Whisper. After 190 years of imprisonment, this ghost-like creature is glad that someone has been kind enough to set him free. He decides to reward Keita by becoming his guardian against supernatural forces. Whisper is one of many Youkai that exist in the world, and provides Keita with a special Youkai Watch, which enables him to see and interact with all the other Youkai. Youkai Watch follows Keita, Whisper and the cat spirit Jibanyan as they encounter Youkai, befriend them, fix all the trouble that they so often cause, and, with the help of the watch, use the powers of previously encountered Youkai to aid them. Young Keita may have been just an ordinary primary school student when he first encountered the Youkai, but the many adventures that follow his discovery provide him with invaluable experiences and precious life lessons that help him grow.
