Anime Profile: Shonen Onmyouji

Thirteen year old Abe no Masahiro is the grandson of the great and powerful onmyouji, Abe no Seimei. Due to the loss of his Kenki ability (sixth sense), he was unable to become an onmyouji who will surpass his grandfather, whom he always called 'old fox demon' or 'old racoon'.

It was revealed that his grandfather had sealed away his Kenki ability for his safety when he was younger. When he was sitting under a tree one day, a weird dog-like mononoke (monster) with long ears and red eyes fell down from the tree. Mokkun, which Masahiro named the mononoke, followed Masahiro since then and protected him from harm.

Guren/Touda, another form of Mokkun, is actually a Shikigami who protected Seimei earlier, but choose to protect and safeguard Masahiro since he was a baby due to the fact that Masahiro amazed him by being not afraid of him like most people. After Masahiro regained his lost ability, he now works hard to be the best onmyouji who will not sacrifice others and to surpass his grandfather.
