Onee-sama was going to school. This was important, because Onee-sama had to prove how smart she was to all the plebeians and filth who were unfit to be in her presence.

But just because Onee-sama was the best did not mean that she didn’t need help sometimes. That’s why Poppu was hanging from the wires holding up the ceiling panels, arms and legs extended to lock her in place while Onee-sama placed all her things on her desk.

It was a good hiding spot. The light would blind anyone looking up, and she was small and dark and a ninja, so no one would see her. And if they did see her; well, she was a ninja.

Onee-sama was about to sit down when Poppu’s ninja eyes saw the spilled juice on her seat. Thinking fast, Poppu pulled a kunai -she had made it herself from a fork- and some wire that she ninja-borrowed from Crochet, tied the wire to the fork, then flung it out.

The fork wrapped itself around the chair in the row next to Onee-sama’s.

Poppu yanked hard, and with a scrape, the chair slid over just as Onee-sama was sitting and bumped Onee-sama’s dirty chair out of the way. Onee-sama blinked at her old chair which had tumbled aside, but she was sitting on the new, clean chair already.

Poppu wiggled her hand, undid the wire’s loop, and quickly pulled it back up. Mission accomplished! Onee-sama’s butt would not be sullied under her watch.

Now, Poppu just had to find out who had spilled juice on Onee-sama’s chair and dispose of the body. Onee-sama would be very proud, and she would pat Poppu’s head, and give her hugs, and when Poppu asked for an orange jumpsuit Onee-sama would make that ingrate Crochet make one for her.

She focused a bit more when some girls moved into the room and started walking towards her Onee-sama. They were probably going to grovel and beg for Onee-sama’s attention.

She stared with mounting anger as the two girls, one an ugly red headed gaijin and the other some clueless brunette, laughed at her Onee-sama.

Onee-sama didn’t kill the girls because Onee-sama was like a kami of patience and righteousness and would not sink so low. She wouldn’t bloody her hands, because those hands were for patting her imouto.

The class started and the girl returned to their seats. Poppu held back. If she cut their heads off now, some of the blood might land on Onee-sama and that would mean that Crochet would have to clean Onee-sama’s clothes and would earn more love.

No, Poppu would need to wait. But ninjas were good at waiting, and waiting meant thinking.

It took some time for her to realize that just killing the girls might not be... good. Onee-sama was partial to ‘good’ things. This was normal, because Onee-sama was the best thing, so she would want others, like her imouto, to have good things.

Yes, killing the girls would be ‘bad.’ Doing 'bad' things meant that Onee-sama would threaten to spank her. So Poppu needed to do something else.

One of the girls, the one with the ugly red hair, stood up after saying something to the fool of a teacher at the front. She simpered at him and he allowed her to stand and leave.

Poppu brought her hands together over her chest, like they showed in the animated documentaries at home and made the seals her favourite characters used. “Imouto ninpō: shi no kage,” she whispered.

The clone that remained behind would hide in the shadows watching Onee-sama until she turned to dust.

Poppu appeared behind the redhead just as the door clicked shut. She moved, stuck right up behind the girl so that when the girl started walking, Poppu matched the motions with only a breath of room to spare.

The girl laughed to herself as she moved deeper along the corridor, and Poppu wondered if maybe disposing of the body would be that ‘bad’ after all.

The girl walked into a filthy bathroom and Poppu had to think fast or else she would be seen in the mirror. She ran through her hand seals again and teleported to the corner of the ceiling, her clone slipping out into the corridor to go see if Onee-sama was safe.

For now, Poppu would wait for an opportune moment.

It came faster than she would have thought. The redhead used the stall next to Poppu’s hiding place. Soon, the air stank of evil gaijin poop and Poppu had to focus on her ninja ways not to gag. But it did give her an idea.

Uncoiling her ninja wire, she quickly tied it into a knot, then a loop and prepared for the toilet to flush.

It never did. The stupid redhead opened the stall door and started towards the sink without even flushing. That was something Onee-sama was very much against. Not flushing at home meant Onee-sama would be upset. This redhead was truly repulsive.

Poppu moved into the stall, and just as the redhead was moving by, she tossed her loop like a lasso and grabbed the girl by the neck. “Imouto ninpō: Kusottare,” Poppu whispered as she yanked.

The girl tripped, turning just in time so that when her head landed in the toilet, it was face first.

She screamed, squealing and flailing her arms like a fool. Poppu used the distraction and her target’s blindness to teleport behind her and pull out her tanto. With a single swipe, the toilette water-covered floor turned red and Poppu knew that her work was done.

She slid out of the bathroom and back to Onee-sama’s classroom. It took some time for someone to open the door, but when they did, she was quick to return to her hiding place near the ceiling. It was only when she was sure that Onee-sama was safe again that she allowed herself to smile.

The smile grew when the redhead burst into the room, her top all wet with poop water, her make-up running and the class suddenly smelled like a bathroom. But it was her hair, shorn short by a sharp knife, that really made her stand out.

When Poppu saw Onee-sama holding back a laugh, she knew that she had done a good thing.
