Bookmaster

Replacing the Wizard enemy from the original game, Bookmasters (ブックマスター) are Emblem Heartless and close relatives to the magic-using Heartless such as Crimson Jazz. Like their predecessor, Bookmasters first appear in Hollow Bastion.

Bookmasters can use all forms of magic other than Magnet, Reflect, and Cure. They can also hit you with their book, which appears in a Japanese fashion based on its cover side. This attack is hard to deflect. Their magic hits from quite a distance, so it's best to hit fast and hard with the Keyblade.

There is a small chance that defeating a Bookmaster will reward Goofy with the Akashic Record weapon.

A more powerful version of this Heartless, called Runemaster, appears in the Cavern of Remembrance in Kingdom Hearts II Final Mix.

Design
A Bookmaster is a rather small Heartless that wears long robes that cover its feet. These robes are predominantly green, with a yellow collar and a number of blue designs decorating them. It also wears a tall, cylindrical, green and white hat and what seem to be brown gloves. The only part of the Heartless no covered by clothing is its face, which somewhat resembles that of a Shadow, sporting the same black, spherical head and yellow, glowing eyes. All Bookmasters hold a book known as the Akashic Record.

In Kingdom Hearts II Final Mix, a Bookmaster wears predominantly yellow robes with an orange collar and brown patterns decorating them. Its hat is yellow and brown, and it carries a differently-colored version of the Akashic Record.

The Bookmaster’s name is an obvious reference to the spell book it carries and fights with, and its skill in using it.
