Toei Animation’s official website for Dragon Ball Kai was updated over night with a nice little face-lift to reflect the upcoming Artificial Human arc. They have also updated the majority of their sections with new information regarding this story arc, in addition to removing their bulletin board. However, they note that the bulletin board is being replaced with a new “special” section which is still listed as “coming soon”.
The cast page confirms (but you already knew this, right?) that Takeshi Kusao will be returning to provide the voice of Trunks. It also confirms that both Gyū-Maō (Ox Demon King) and King Cold will be voiced in Kai by veteran voice actor Ryūzaburō Ōtomo, both of which were originally voiced by the late Daisuke Gōri. Ryūzaburō Ōtomo recently stepped into voicing the role of Porunga in the last few episodes of Kai, but most will know him as either the voice of Dabra in Dragon Ball Z or Ryū Shinron from Dragon Ball GT.
The page also confirms the song title of the new ending theme that will air tomorrow with episode 55: “Wings of the Heart” (心の羽根; “Kokoro no Hane”). The new ending theme is being sung by “Team Dragon”, which is formed by members of the idol group AKB48. The theme’s lyrics were written by Yasushi Akimoto and the song was composed by Kensuke Yoko, who have both worked on AKB48 songs before.
