"It's… so… HOT!" Len groaned, collapsing on his lawn chair. He was in a pair of bright yellow swim shorts and flip-flops. His body was sweaty all over from the heat. "Meiko promised to take us all to the pool, but guess what! The pool is closed! Ugh! Why is it even closed anyways?"

Rin, who was in an orange two piece, flip-flops, and had sunglasses on her head in front of her bow, looked at him and said, "It's Fourth of July here! It's a holiday so it's closed."

"We don't even celebrate that holiday!"

"America does, and since we're here for vacation, we have to respect that," she said matter-of-factly from her beach towel on the grass. "So shut up and go inside the house."

Len grimaced at her. "The AC is broken. Haku is coming to fix it later."

Rin rolled her eyes and thought for a second. "I know! Let's go ask Kaito for some of his ice cream!"

The other twin nodded and they ran inside the house to find him.

Kaito fixed a hard stare on them both. "You really think I'll give you some of MY ice cream?" He was dressed in blue trunks as well, along with sandals and a towel around his heck instead of his scarf.

Rin shuffled her foot on the wooden floor of their beach house and muttered, "Well… yes?"

To their dismay, the older Vocaloid shook his head. "No way, Josè. It's mine," he said sternly. "Go bug Miku for some of her Leeksicles or something."

"Ew, gross, no way," the twins said in unison.

Kaito sighed, "There's a water hose out there. Go play with the friggen water hose."

They shouted "Yay!" and ran back into the lawn.

"Okay… how to you turn on this thiaaAAAAAAHHH!" The water sprayed into Rin's face, soaking her hair and bow. Spitting out some water she said, "Figured it out."

Len snickered, then snatched the hose from her and sprayed her again, making her squeal.

"Len! That is totally unfair!" she yelled at him, taking the hose away from him.

He smiled. "All's fair in love and war, my dear sister! Maybe one day you can learn to-" Len couldn't finish because Rin squirted him in the face with more water.

"I think I already did," Rin laughed.

Len growled playfully, then jumped at her, shouting, "You asked for it, you brat!" He tackled her to the ground and started spraying her with water. Rin tried to push him away, giggling as she did, and they started rolling on the grass.

Meanwhile, Haku had arrived in a white tank top and gray and purple shorts with a toolbox in her hands. She said, "I'm here to fix the-" She froze when she saw Len and Rin rolling on the ground on top of each other.

"Um… I'm going this way now…" She stepped away from them, then charged inside, almost knocking Meiko over in the process.
