The Otawai

The otawai is a ancient worn out and tattered green color book possesed by chowa honoka.

overview
Originally this book was said to belong to Ikari but later it was revealed that the book was handcrafted by the two familys who form the honoka clan. This masterful history would lead Aisuru, kashikois wife, to refurbish the book with thousands of sealing forumlas sewn into each page.

Abilities
While the book itself does not possess any rare powers, the sealing forumlas incompassing the book are said to have the ability to collect chakra thought waves. This unqiue trait allows the book to both keep track of the clan lores and abilities, but also project holograms of those who came before and the knowledge they possess.
