History's Strongest Disciple Kenichi Official Guidebook

== Summary ==
History's Stongest Disciple Kenichi Official Guidebook was authored by Syun Matsuena. The Shinpaku Alliance and Haruo Niijima are listed as supervising editors and collaborators. It reads as if it was written by Niijima himself.
The guidebook contains amongst others color illustrations that were published in Weekly Shōnen Sunday Magazine during the series' run, character profiles, columns written by Niijima that reveal "secret" information, an interview with Syun Matsuena, and a making of that explains how a manga page is drawn.
The character profiles list a character's affiliation, ki type, nickname/title, age, birthday, height, weight, measurements (female characters only) hobbies, likes, dislikes, grades (for those who still attend school) and dreams for the future. Character pages can furthermore contain a battle log, a list of techniques used by that character, information tidbits and comments by Matsuena. The amount of information given depends on the importance of a character. .
== Credibility ==
All data has been compiled by Matsuena and his staff from Wazadepa and thus can be considered canon. However, this guidebook was published several months before the series ended and thus does not contain information about events, developments and characters that appeared after its publication date. No revised second edition has been announced so far.
