Kakashi’s real face is one of the biggest mysteries in Japanese animation, however, that mystery might finally be solved this April 25 once the “NARUTO” exhibition opens in Tokyo.

The event’s official guest book, Shinden Fuu no Sho, is being teased to be the one to reveal Kakashi Hatake’s actual face. The guest book will be illustrated by Naruto creator, Masashi Kishimoto himself, and will include new manga scenes. It will also include a dialogue between Kishimoto and his long-time rival, Eiichiro Oda, the creator of One Piece. It will cost 1,300 yen.

The exhibition will be held in Tokyo from April 25 – June 28 before heading to Osaka from July 18 – September 27, 2015.
