On their second day of being throuple, Hakari and Karane get Rentarou to start calling them by their first names and holding hands as they walk to school together going on about how perfect the weather is. They arrive to a harrowing scene: the perverted vice principal chasing down a boy and giving him a deep, sloppy French kiss. When Rentarou states he’s yet to kiss a girl as they’re his first girlfriends, Hakari and Karane enter into a battle for that first kiss.
Their first opportunities come up during lunch on the rooftop. Hakari starts by feeding Rentarou tamagoyaki, and a panciked Karane jams a cookie into his eye. Hakari then produces a box of Pocky (called “Bocky” here) with the hope that sharing one with him will lead to a kiss.
Karane sniffs out Hakari’s intentions and tries to get in there, but ends up poking his other eye. The two then see his two red eyes and think he might be sick, and are desperate to check him for a fever. Whenever Karane gets too close, Hakari bounces her away with her chest.
When Rentarou realizes they’ve both been trying to kiss him, but the core of their conflict is who gets to go first, he devises an extremely convoluted solution involving iPods playing “My First Kiss” on max volume and repeat, blindfolds, and sets of dice which which will sufficiently randomize the order of the kisses.
This goes pretty well…if manic hijinks were the intended result. The blindfolded Rentarou has to grope around and ends up in compromising positions with Hakari, while a cat deciding to play with the ribbon on Karane’s panties leads her to think he’s pawing her, so she clobbers him with every attempt. All of this is as hilarious as it is lovingly drawn and animated.
When this strategy fails, Hakari and Karane continue to bicker with one another, until Rentarou runs off, deciding that if the question of who gets to kiss him first causes so much strife, he’ll throw his first kiss in the trash by running in the halls and getting nabbed by the perverted vice principal.
Once again, Harane’s athleticism and wrestling acumen come in handy restraining the vice principal before her blender blade of a tongue can shoot down his gullet. Hakari also helps out by calling for an official from the education board who would get the principal fired for kissing students.
Hakari and Karane may vary differently in a great many things, but they’re alike in their deep love of Rentarou, so rather than letting him be assaulted by the vice principal, they each declare simultaneously that they’d rather the other girl kiss him first. Moved by their selflessness, Rentarou hugs them both.
The ultimate solution ends up being the simplest, and one Rentarou thought up first, but didn’t think would work because the girls were at loggerheads: they’ll simply kiss him at the exact same time. While initially reticent due to the fact they’ll also be kissing each other, Hakari and Karane agree that it’s the best solution, since at no point does either girl doubt how much the other girl loves him.
So the three take each others’ hands and lock lips at the same time, cementing their status as a legit three-person polycule (and possibly summoning a UFO). But it won’t last long in this state, because when the three are in the library, Rentarou reaches for the same book as a petite blue-haired girl. When their eyes meet, she is confirmed to be his third of 100 soul mates. To which I say, Let’s freakin’ go!
