One day, at the Nanase residence
"Why are we here again?" Rin asked, sitting in the living room with the other four swimmers. "And why does your living room have a stage?" He questioned Haru, gesturing to the small stage that was set up.
"Kokoro wanted to show us this comedy act she thought of." Haru replied. "Now be quiet, it's about to start. I want to film as much as I can." She said, holding a video camera in her hand.
"You have some cousin complex, don't you?" Rin remarked.
Then the stage's curtain rode up. On the stage of was Kokoro, who was sitting on her knees and wearing a light blue kimono.
"Thank you all for coming." Kokoro said. "I hope you all find my act entertaining."
All five swimmers clapped their hands.
"I shall start now." Kokoro announced. "In one hand, we have Nagisa-onii-chan; in the other, tofu." She pulled out a closed fan and tapped it on her head. "One is bland, while the other is blonde."
"Oh, how clever." Nagisa remarked.
"In one hand, we have Mako-onii-chan; in the other, a tiger cub." Kokoro continued. She tapped her head with the closed fan again. "One will grow up to be a scary cat, while the other is already a grown scaredy-cat."
"That's hurtful." Makoto said.
"In one hand, we have Onee-chan; in the other, water." Kokoro said, tapping her head with the closed fan. "One is colorless, while the other is often emotionless."
"Mmhmm." Haru nodded her head, stilling filming her cousin's act.
"In one hand, we have Onii-chan; in the other, a block of ice." Kokoro tapped the fan on her hand again. "One is known for it's coldness, while the other is known for his tsundereness."
"Wait just a minute here." Rin said.
'The last joke must be about me.' Rei thought.
"In one hand, we have Rei-onii-chan..." Kokoro trailed off, her mouth hanging slightly open.
Suddenly, the stage's curtain closed.
"Eh?!" Rei exclaimed in shock.
Kokoro-chan couldn't think of anything to compare Rei-chan to, so she skipped him.
