Any information that links to this page originates from an autograph session with Watanabe Wataru. It has become a tradition that fans attending the autograph sessions ask questions about various characters and post Watanabe's replies on twitter for others to see. Because Watanabe is answering these questions on reflex, this information is subject to change. Once these facts are recorded in the manga/fanbook, or Watanabe confirms them at another time, they will be considered officially canon and can be unlinked.
It also should be understood that anyone can post information on Twitter claiming it is trivia Watanabe has stated, and that information can become misconstrued when transmitted from one person to the next, one medium to the next, as well as when translated from one language to the next. Therefore, each bit of information should be taken with a grain of salt even if listed on this wiki.
