Chapter 5: The Seven Who Summon The Storm
Part 1: Leader’s Duty

  • Tsumugi was on the phone with Kaoru before Otoharu asked her to gather all of IDOLiSH7 to announce their new song.
  • Iori asks Otoharu who composes the song they sing to which Otoharu responds that it's a corporate secret and to "Breathe life into these songs, so that many people will hear them."
  • Mitsuki says "...Even the president is putting on airs." and Riku theorize if Otoharu himself makes them, which Tsumugi wonders if he can compose music.

Part 2: Secret

  • After Tenn mentions that Gaku and their president likely don’t think that way. Some lines are taken out where Yamato says Gaku seems scary, which Tenn agrees and compares him to a werewolf that transforms under a full moon. Tenn roars and Yamato gets scared, saying "We’re all herbivores over here." Where Tenn responds, "Should I make my hands white with flour and chew on some chalk? Seven Young Kids." Yamato then says "I’ll make sure to hide in the grandfather clock." Which is all a reference to the short story The Wolf and the Seven Young Kids.

Part 3: Starting up the New Song!

  • Nothing changes in this part.

Part 4: The Best Waste of Time

  • Nothing changes in this part.

Part 5: The Voice that Disappeared into the Storm
