Some of the girls are already terrified and exasperated by Nico and her co-conspirators' prank when everyone is suddenly beset by zombies! They must just be another part of the prank, or so they think.

Everyone decides to hole up in the house to defend against the zombies. But their only way to contact the outside world is out in the shed! Can they all make it through the night unscathed?!

Everyone is totally exhausted from the tense night. They manage to make it to the next morning safe and sound and take a bit of a breather.

Smiles finally return to the faces of the girls at breakfast after checking the area surrounding the house and finding no traces of zombies. Then they attempt to use the radio in the shed to send an SOS to the mainland…

After some careful thought, the girls question if the zombies they saw last night were actually innocent victims who washed up on the island for some reason. They rush to scour the island to provide help, but what do they find?

All signs point to zombies being on the island. The girls want to leave as soon as possible, but the radio and phones are useless, so they must wait until their boat returns. Amongst their fears and panic, night falls once again.

After exhausting all other options, the girls hole up back in the house. They try to distract themselves, but the sound of the wind frightens them. Worried that the zombies will return, they decide to keep an eye on the cave.

Once the girls arrive at the cave they see the zombies dancing around a bonfire! Their dance is so fascinating that they must be the nine girls from Nico's ghost story! Empowered, the girls decide to go dance with the zombies.

The curtain falls on the zombie incident, so now everyone can get a good night's rest. The girls invite Aqours to join them after they finish their promo video shoot and a renewed three-school training camp begins!

The fun and slightly heart-pounding training camp comes to a close and the Nijigasaki High School Idol Club members are finally home. While they enjoy talking about this and that, new transfer students arrive on the scene…
