Thanks! So this had Taylor Swift (State of Grace, I Knew You Were Trouble), Pink (The Truth About Love) and Adele (Rumour Has It). But no Ebichu and tons of green screen.

Rina and Hinata asked Ike-chan to write a Bonsai song in an insolent manner.(Of course, It's a joke)
They are always insolent to Ike-chan.

Ike-chan:Why must I write a Bonsai song?
Hinata:You have a genius for music.
Ike-chan:You should ask Tamurapan or Hyadain for composition.
Rina:Don't grumble!
Hinata:Do you know why she said violent language to you?
Rina:Ike-chan, You have to write a song.
Hinata:That is only the reason why you are here.
Ike-chan:hahahahaha

WHO is the voice of the first Shinpaku?
