Suri and Miki found themselves in a classroom with a few dozen catgirls. "Hi there! Welcome to Nyekomimi Club-nya!" Said a pink haired catgirl with two tails.
'well, no going back now...' Miki thought. "Hi, we were hoping to join your club, if that's alright with you..."
"Purrfectly Fine-nya, always willing to help a Nyuman bring out their true self, I'm Nyeko-Sakura-Chan, now who wants to go first."
Suri stepped forward, "I'll do it." Miki knew that Suri always wanted to be a catgirl, she guessed that this may not have been luck.
Sakura took Suri's hand and lead her to the center of the room, where she then handed her a ball of yarn. At first, Suri was uncertain, but then she found herself batting the ball left and right before tossing it away accidentally where a catgirl caught it, played with it a bit before throwing it back to Suri, as she played her human ears vanished and were replaced with cat ears at the top of her head, the same green as her hair, at the same time she started to grow a tail.
Suri's transformation completed and Suri now playfully tossed the ball of yarn to Miki. "Nyahaha, Come join me Nyachan."
The blue haired girl smiled and started to bat at the yarn ball just as her twin sister did, losing her human ears for blue furry cat ears and a matching tail.
"Miki-Nyachan you look so cute with those ears." Suri purred, Miki purred back, "Suri-Nyachan you look just as cute-nya."
"Now then." Sakura said. "With the added additions of Suri and Miki-Nyachans, let's discuss what we shall be doing."
