Gyaru Death

Aki's target was a 17 year old highschool girl called Misa Miyatake.
Unbenownst to Misa's parents, the girl was selling her body to dirty old businessmen. Unfortunately, Misa was dumb enough to try blackmailing one of her clients for more cash. That decision would lead to an untimely end for Misa.

Aki followed Misa as the girl walked home from school. The girl was unmissable, being 6'4" and with a body built like a JAV star.
Her long, flowing hair was dyed dirty blonde, and her school uniform was two sizes too short, and cut down to almost nothing in order to show off as much of her tanned flesh as possible.
Her large breasts bounced in rythm to her steps. Misa hummed along to a song, oblivious to her impending death.
The schoolgirl turned down a dark alleyway, a shortcut that usually cut 10 minutes off her commute. Aki followed, slowly unsheathing a katana.

Aki slowly crept up to the slutty teen. Misa stopped as one of her shoelaces came undone. She got down on one knee and began to tie it together. Aki sensed her opportunity, and leapt into action. Her sword came slicing down, neatly separating Misa's head from her shoulders. The busty schoolgirl's body fell back, twin jets of blood spraying from her neck, while her head flew forward.

Aki walked over and grabbed Misa's head by her hair. The teen's face was frozen in an expression of shock, her soft lips parted in an O. The assassin snapped a selfie with her target's head, then casually threw the grisly object into a trash can. Misa's headless corpse was sprawled out on the dirty concrete, still shivering. Her massive tits had escaped the skimpy shirt containing them. Aki stepped on one as she reached down and sliced open the dead teen's flat stomach. She reached in and tore out Misa's heart.

Proof for her employer, and another heart for her collection. The assassin smiled happily.
