"Overcoming "Dull"" (｢だるい｣を超えて, "Darui" o Koete, Viz: Transcendent Drab) is chapter 528 of the original Naruto manga.
Darui realises if he stays silent too long he will be sealed away. Ginkaku tells Darui that he is just a tool of the Raikage. Darui then tells Ginkaku that he is the Fourth Raikage's right arm, and is more than just a tool. As he begins to be sucked into the gourd, Darui realises that two words he said sounded like his taboo word "dull". As he is sucked in Darui apologises to many people, making "sorry" the word he has said the most. Darui knocks Ginkaku into the rope, and manages to steal the sword, and gourd. Darui curses Ginkaku with the sword, and as Ginkaku pleads for Kinkaku's help he is sucked in to the gourd. Enraged of his brother's capture, Kinkaku then enters into his Version 2 form.
