Sarutobi is a ninja and bounty hunter who starts out traveling with Princess Paffy and her priest in something like the capacity of a bodyguard and money maker for them. He possesses a Ryu Ninja called Bakurastumaru. (It is a dark navy color.) He is something of a hot-head and know-it-all. He is also an avenger, with the traits that entails. He has a running rivalry with Adeu throughout the series and often refers to him as the "Sonic Buffoon".

The story is set in “Earthtear,” a mythical world filled with legends and mysteries where monsters, fairies, giants and magicians live. Adeu goes on a journey of training with a robot, Ryu, that has a will and mind to become a real knight. But their enemies have stolen up behind them with the aim of controlling “Earthtear.”<br><br>
