Trivia

 * refers to bubbles on the surface of a liquid. Idiomatically, it also means "transient," "ephemeral."
 * Utakata's sash in the splash page was red, but in the 2nd art book he was shown to have a yellow sash.
 * In an upcoming filler arc in the anime, Utakata and the Six-Tails remain yet to be captured by Akatsuki. In order to avoid conflict with the manga, it seems inevitable that, by the end of the arc, Utakata will have been captured and the Six-Tails extracted, resulting in his previously-unseen death.
