"OMG GUYS BALOONS." Nagisa burst in on the swim team sitting in Rei's living room. Well, Iwatobi swim team as well as Rin, Nitori, and Gou to be exact. They were all studying together for this big exam, but that didn't matter to Nagisa now. "GUYS I FOUND A HUGE STASH OF BALLOONS IN REI'S MEDICINE CABINET"
"Nagisa I told you to stay out of there!"
"But dude you have anti-depresents that stuff is whack if you mix it wi-"
"Are there...water balloons?" Haru stared intensely at Nagisa as if willing an answer out of him
"Nah, the type for balloon animals. Do you make balloon animals Rei?" Rei adjusted his glasses.
"W-we don't need to talk about what sort of organic shapes are constructed using those inflatable pieces of-"
"Ohhhhhh are there any SPARKLY ones?" asked Nitori.
"Can we set them on fire?" Rin glared at Nagisa, pulling out his lighter.
"Guys I really think we should study..." said a quiet, orcaish voice in the background.
Nagisa began to blow up balloons, handing each one to each person in the room.
"Lets see what we can make out of them guys!" Nagisa began to twist his, but it quickly popped. This continued on with 4 other balloons. Haru leaned over to Matoko, quietly displaying his "dolphin" which looked a bit more like a rancid banana. Rei had made a model of a plutonium atom. Gou sat in the corner with a perfect replication of someones manly chest. Nitori was drawing eyes on his, and Rin sat quietly in the background try to set his on fire. "Guys I keep breaking mine!" Complained Nagisa.
"Let it set me set it on fire..." Rin grabbed for Nagisa'a balloon, but Nagisa pulled away, not wanting another balloon to be destroyed. In the process he dropped his balloon and set Rei's apartment on fire. They stood outside, watching it burn.
"Its sparkly!" Cried Nitori.
"Looks pretty sweet" agreed Rin
"It's certainly a wonderful example of the beautiful power of nature" Rei pushed up his glasses.
Haru simply continued to try and show his wonderful creation to Makoto while Matoko cried bitterly.
And that's why we don't let Nagisa snoop in peoples medicine cabinets.
