The FNS Kayousai was a 4 hour song program with many singers. There were a couple anime song medleys during the program, and several seiyuu participated.

The seiyuu songs were as follows.

• Mezase Pocket Monster (Matsumoto Rica, Nogizaka 46)
• Testament (Mizuki Nana)
• Zankoku na Tenshi no Teeze (Takahashi Youko, Mizuki Nana)
• Youkoso Japari Park he (Doubutsu Biscuits x PPP, Keyakizaka 46)
• Hare Hare Yukai (Hirano Aya, Yamamoto Sayaka [NMB48], Matsumura Sayuri [Nogizaka 46])
• Aozora Jumping Heart (Aqours)

For the Kemono Friends part, the eight Doubutsu Biscuits x PPP members were joined by several members of Keyakizaka 46, and they sang and danced "Youkoso Japari Park he".

For the Aqours part, they showed the animated video of the song on the screen in the background, and showed quite a bit of that too (instead of the seiyuu).
