"Seriously, what have you done to him?" the turquoise-haired whispers, all the while cupping her mouth and darting her eyes around to make sure no one in the cafeteria is paying any attention to her. She is lucky, for everyone is now too occupied with the sight of Shion Kaito dancing half-naked on a table to notice. Situated at one of the special seats for this unexpected show, which is at the table he is dancing on, his older sister Meiko shouts and cheers him on while filming her poor brother with her iPhone 6 Plus. The precious 1080p video with crystal clear audio will be the perfect blackmail material later.
"It's nothing, really." Haku whispers back, "I just added one drop to his ice-cream shake... Don't worry, the effect will wear off when lunchtime is over. Looks like your revenge plan came out with flying colors!" she gives Miku a triumphantly devious look, and the leek-lover says defeatedly, "Fine, I'll treat you after school... oshiruko maybe?"
"Oshiruko." Haku nods.
This is no doubt the perfect ending for the vengeance plan that Haku finds herself being a part of. Yesterday, Miku was on the warpath as her ex-boyfriend Kaito released an embarrassing photo of her nodding off at her desk in Math class on Facebook. The half-elven isn't on friendly terms with her since Miku is already a famous teen pop star, and Haku doesn't like teen stars. But seeing her outrage over the stupid blue-head who Haku absolutely hates, she agreed to side with the leek-lover for once and hatch a perfect plan to hold Kaito accountable for the wrong he had done. It was incredibly fortunate for Miku to choose Yowane Haku as her partner-in-crime since not many people know of her expertise in poison. Haku is proud of her poisoning skills acquired during her time in the elven tribe north of Hokkaido (though she wishes she could complete them by knowing how to fire poisoned arrows). Not only is she able to create all sorts of substances that don't actually kill but make a healthy person fall ill or go nuts for eternity, which is what beginners or the feeblest of elven poisoner can do, she can also whip up concoctions whose effect is only temporary, like the one she spiked Kaito's ice-cream shake with, which is something only advanced poison-makers are capable of and is only taught to an extremely limited number of elves. Nobody in Tokyo knows the recipe to such things but Haku, and she can mix them up almost anywhere, anytime as the ingredients can be found all around her. Yes, she can make antidotes too, but they don't appeal to her as much.
"Hey" says Gumi to her as students begin to move out of the cafeteria, "I overheard you talking with Miku. Please, I need you to help me poison this person..."
