  Kaito stared wide eyed at Maki, who was his classmate at Hope's Peak Academy. She was known as the Ultimate Child Care-Giver, which was strange regarding her personality. However, Maki was now looking at him darkly. The Ultimate Astronaut had followed the brunette when she suddenly disappeared during the last class of the day. Something she often did, however, the school refused to acknowledge that she did this.

  Standing behind the petite girl was a body with a slitted throat, Maki made no move to hide it.

  "What do you think?" Maki asked coldly, glaring at Kaito as if she might kill him next.

  "You're an assassin?" Kaito asked slowly, looking at Maki curiously.

  "What gave it away?" She hissed.

  "Are you hurt?" The question startled the red assassin.

  "Do you wanna die?" Maki growled, moving away from him when the astronaut moved forward to inspect her.

  With a huff of annoyance, Maki disappeared down a dark alleyway. When Kaito attempted to follow, he found that she was good at what she did, there wasn't even a scrap of evidence that she had ever been there.

  "Ultimate Child Care-Giver, huh? More like Ultimate Assassin." Kaito muttered.

  Kaito continued to follow Maki around, even adopting the nickname, Maki Roll. The pair would sometimes work together to carry out Maki's assassination mission which she was given from an unknown source, at least, that's what she told Kaito. It was this mission in particular that Maki denied Kaito's presence all together.

  "Why not?" Kaito demanded as they stood behind Hope's Peak Academy after school.

  "Because this one reqires my utmost attention." Maki hissed softly, her red eyes glowing threateningly.

  "Well too bad, I'm coming. You might need help." Kaito crossed his arms over his chest.

  Maki lunged at him, holding with above the ground with one arm while he gasped in surprise.

  "Listen to me." She snarled, making shivers of fear coursed through him. For an instant, Kaito wondered if this was how her other victims felt, "This is the most important mission for me so far. I can't have you around to distract me, okay?"

  Maki dropped him and whisked away from the winded astronaut. Kaito quickly chased after her. After working with her for a few months, Kaito had learned the basics of assassination. Like being quiet.

  Maki leaned against the wall of an old school building, pulling out her phone with facebook on it. Carefully watching the doors as she waited for her target. The Holy Salvation Society had told her that the target was someone who they couldn't take in, and needed to be killed since he knew too much. Maki never bothered to remember their names, they'd just die anyway. Maki felt the knife's cold blade pressing against her waist as it was hidden horizontally in her belt..

  After a few minutes of waiting, her target walked out of the building accompanied by another male. The one she was supposed to kill was a short male with light blue hair styled to that of a girl's, the male walking beside him was much taller with red hair.

  They both held themselves similar to those she saw around the HSS, where they assassins too? Shaking away those thoughts, she began to follow them, making sure to seem as if she were window shopping since she had done these kinds of missions before. However, something told her to be extra careful.

  They turned into a deserted part of the city, somewhere that not a lot of people were and, by chance, they were completely alone. Masking her presence well beforehand, Maki unsheathed the dagger on her belt and flashed out of her hiding space. She was seconds away from ending his life when he easily slipped away from her.

  The red haired one, took the blue haired one's place and started using martial arts against her. She was skilled in this type of training since they literally pounded it into her. Easily dodging each blow, managing to get a few hits in, she ducked around the redhead and starting taking swipes at the bluenette.

  Nagisa. That was his name, Maki remembered in a flash. In her second of distraction, the male in front of her managed to get behind her. Oops. Ducking and whirling around, she managed to leave a large cut on the shorter one's chest, narrowly missing his throat.

  She had forgotten about the redhead, who for some reason also had a knife, stabbed her from behind, hitting in between her shoulder blades. Knowing the mission was a failure, she disappeared in a flash of speed, making it around the corner and into an alleyway before collapsing, breathing heavily.

  Kaito rounded the corner, his face pale as he rushed to the young assassin's side, blood blending into her red top.

  "I'm fine..." Maki huffed, pushing herself up the wall.

  Kaito caught her as she stumbled into him, "This is why you should've let me come."

  "I didn't know the redhead would be with him..." Maki hissed.

  Kaito rolled his eyes, picked the girl up bridal style and carried her back to his house since he didn't have her key. The assassin had gone unconscious, leaving Kaito alone to treat the stubborn girl. Binding her chest and back with tight bandages to limit the bleeding, fighting back blushes while doing so, Kaito laid her on the couch.

  After a few hours, Maki finally started to stir. Blinking her red eyes open, she saw Kaito hovering above her. Fierce pain expanded from her back, however, she was trained against torture and, pain in general, so she showed no sign of pain.

  "What are you doing here?" Maki asked slowly, blinking her scarlet eyes.

  "Taking care of you. You got stabbed." Kaito explained.

  "How did you find me?" Maki asked as the astronaut handed her a glass of water.

  "I kinda followed you." Kaito admitted, rubbing the back of his neck with a hand.

  "So you saw, huh?"

  The male nodded, "They disappeared in the same fashion you did. Were they assassins too?"
"Probably. Good ones at that." Maki muttered crossly.

  "Can I come with you next time?" Kaito asked, sitting next to her as she slowly sat up.

  "You'll follow me anyway..."

  "You got me there." Kaito blushed when Maki rested her head against his shoulder.

  "And, thanks..." Maki whispered, almost inaudible.

  "Y-yeah." Kaito smiled, making the Ultimate Assassin smile too. Maybe having Kaito around wouldn't be so bad?
