The Laid-Back Youkai Dictionary is a book given to Abe Haruaki by Miki Rintarou, a fellow teacher at Hyakki Academy. Published in the year 2000. The tagline on the book is 'More Info Than You'll Ever Need!' However, it often contains incomplete or lacking information. This problem is made worse by the occasional stains through the book. It also does not contain an entry for Yakubyougami.
