It was springtime in Tokyo, Japan. A girl who was called upon a PreCure Mascot named Mocho, and was granted the power of the dragonfly. Her abilities are to fly at top speed of 25 mph, be able to bite (if possible) and opponent with her sharp fangs (if available), and can regenerate herself whenever necessary.

This girl is Cure Dragonfly, also known as Kana Fukuhara, and with her twin sister named Sana, also known as Cure Moon, fought justice within Tokyo.

One day, Sana was awake because of a nightmare she had.

"S-Sister, are you awake?" asked Sana. Kana was fast asleep, unable to wake up to her sister's calling.

"sigh... Kana, you're such a heavy sleeper. Isn't that right, Mocho?" Sana looked down at the little cat -like mascot of the PreCures.

"It's true! It's true, Mocho! We have to find more PreCures in order to stop Rai, Mocho!"

Sana smiled at him and went back to sleep.

The next day, the twins got dressed for school. Kana and Sana had to leave Mocho inside one of their backpacks until recess.

"It's stuffy in here, Mocho...." Mocho whispered to himself, being squished by books and pens and pencils.

"Sana, what are you doing talking to Itsuka? She's not even very nice to you. Why is that?" Kana looked directly at Itsuka Toin, a tough girl younger than the Fukuhara Twins.

"Oh, is that so? Well, we'll talk. That includes you, Kana!"

"Itsuka, I wasn't listening to anything you and my sister just talked about!" Kana covered her ears, trying to ignore Itsuka.

"Don't worry. I'm not gonna pound on you two. I made up with myself and everyone else."

Outside the school, a tall woman dressed in a black trench coat with black sunglasses chuckled to herself.

It was recess....

"So, what did you wanted me to find out?" Itsuka asked Sana.

"Why doesn't she ever talk to me than to Sana?" Kana thought to herself.

The woman in black appeared to them while they were alone.

"Excuse me, ladies. Is this seat...." The woman then fired a ray gun at them, forcing the table to tip of itself and the three girls.

"Taken?" she laughed evilly.

The three schoolgirls grunted and moaned in pain. Mocho finally popped out of Kana's bag, gasping for air.

"It's all mine, Mocho! All mine, Mocho!" He was "grabbing" the air.

"Itsuka, are you okay?" asked Sana, groaning.

"I'm okay," she grunted.

"At least she talks to me still!" thought Kana.

"Are you prepared to dies or to fight?" said the unknown woman.

Mocho looked at Itsuka and shouted, "ITSUKA, BECOME THE RUBY!" and called out for a girl named Princess Yuki. She appeared and gave Itsuka a PreCure Token with a sign of a ruby.

"What's this?" said Itsuka holding the Token.

"It's your PreCure Sign becoming a PreCure, Itsuka," explained Yuki, and disappeared in mid air, leaving it up to the girls and Mocho.

Itsukaherself automatically shouted out her transform cry, known as "PRECURE READY! SET, START!"

She transformed into Cure Ruby, the PreCure of the red gem.

"You look cute in that outfit, Mocho!" giggled Mocho.

The woman fired another shot at the girls, but was stopped by Cure Ruby's attack, known as the Red Gem Spear.

"Shoot! Well, I guess it's game over for you guys anyway. Hehehe." the woman said as she fired another shot at them. Sana and Kana transformed into their PreCureforms. For twin relatives, they can use the PreCure Double Power to transform together.

"PRECURE READY! SET, START!" shouted the twins. Kana, the PreCure leader of her group, transformed into Cure Dragonfly, and Sana transformed into Cure Moon, the PreCure of the shiny moon.

The owman fled the scene as soon as they attacked.

"Who is she, Mocho?" said Mocho. The PreCure Token that made Itsuka transformed, turned into a ring-like device known as the PreCure Ring. Kana and Sana already had their PreCure Rings since they were early PreCures.
