Wonderful precure the novel: Nyammy's Darkness

A splash in the sea.

Yuki didn't know what to do. On one hand, she felt compelled to fight. On the other, she felt as if her virus was getting worse and worse. Nyammy was so weak that she couldn't even summon the Puni Puni Barrier to defend herself and Lilian. As she tried to summon it, she faltered and was knocked back into the ocean! Nyammy was terrified of the water, but there was nothing she could do.
"Nyammy, No!" yelled her teammates. Nyammy's eyes eventually closed as the water pulled her in. Mayu wanted to jump in the ocean, but she couldn't. She was afraid of the garugaru. What if she failed?
Meanwhile, the rest of the cures were trying their best to fight without Yuki. They managed to get a couple of defenses in, but they were clearly struggling. After thousands of Puni Puni barriers, Ribbon barriers, and Lilian Nets, the garugaru was undefeated. It even smashed the girls into a wall. Lilian, Friendy, and Wonderful were detransformed due to that occurrence. Iroha weakly stood up.
"It's way too strong." She said.
"I know that, but how are we supposed to take it back to The Niko Garden?" Asked Mayu.
The cures knew of one person that was an intelligent butler. Mey Mey!
He always had the answers. Iroha took out the Kiraniko Trunk to get advice for Mey Mey.(A sheep from the Niko Garden.) It didn't take long for him to appear in front of them.
"Hello, Cures." He said Respectfully.
Mayu smiled at Mey Mey and touched his wool. It was soft, much to Mayu's joy. Mey Mey rolled her eyes as Mayu petted him. Mey Mey was paying attention to a big scar on Komugi's face. He immediately was concerned. As much as the cures don't listen to him, they were like family to him.
"Hard Battle?" He asked. Iroha shook her head. Suddenly he began to search around the beach.
"Where's Nyammy?" He asked.
Mayu's face fell instantly.
"Mey Mey, She fell into the ocean."
"I could have helped her, but I was too scared!" Said Mayu. She transformed into Cure Lilian and dove into the water.
"No!!!!!!!!!!!!!!!" Yelled Iroha. She didn't want her friend to be hurt. She transformed with Komugi and together they went to save Mayu and Yuki. Suna saw everything and decided despite her lack of power, she was going to try to be a hero. She jumped in!
