Guardian Ninja Mamoru

In a foiled attempt to kidnap an infant princess, the princess is rescued by a loyal ninja and is hidden in a village where she is raised as a common female ninja. Many years later, some promising young ninja students are about to be put through one final test, to see if they possess the skills required to be accepted as full ninja. They are known as Sakura, Matsuri, Yume, Pochi, and Hayashi, and their mission is to sneak inside the Byakuro Castle and steal a secret scroll. Little do they know that one of them is the surviving princess, nor are they aware that they are being following. We're sure our young ninja cadets can prove they have what it takes to be full ninja, the only question is whether they can do it before they kill each other!

After the death of Saizou, Kabamaru's horribly strict grandfather and Iga ninja teacher (sensei), an old lady, Ran Akoko, claims that she received a letter from him asking her to take care of his grandson. So Kabamaru runs off with Lady Akoko to the big city Tokyo to gorge on yakisoba, ramen, chow mein, and attend a regular school—which turns out to have weird quirks of its own.

Makenko used to be a normal boy -- until he was kidnapped by the brain monster Dr. Mud and transformed into a cyborg capable of destroying both the monster and human worlds! On his quest for vengeance, he is inadvertently joined by Makendo, a fellow monster hunter who would prefer not to be, and her little sister Hikari who would like nothing better! Dastardly demons and wacky monsters abound as the trio fight the bad guys to kick some monster butt, and get Makenko's body back!

At first glance, Nura Rikuo seems like nothing more than a normal middle-schooler. In actual fact, he is grandson of Nurarihyon, master of a youkai clan. Having only recently resolved the hostilities between the Nura Clan and the Shikoku Yokai, Rikuo finds no rest as an ancient enemy of the Nura Clan, Haguromo-Gitsune, resurfaces. After 400 years of inactivity, Haguromo-Gitsune suddenly sweeps through Kyoto with overwhelming power.
