Nagisa was stunned by Karma's expression. As the lights of the train lit it up, the sadistic smile on it only had two results – being stunned by it or being frightened by it for the rest of your life.

Suddenly, Karma's face turned from violent to surprised. Nagisa turned around to see what his friend saw that changed his mood. Behind them, there was Okuda Manami with two large bags in her hands. Her body trembled slightly.

"Ah, good afternoon, Okuda-san!" Nagisa greeted her, rubbing the back of his head. Manami leaned forward in an attempt to greet them as well, but her bags were so heavy that their weight pulled her down.

"Ooops, be careful!" Karma said, pushing her back to her feet. Nagisa had no idea how his friend was capable of being in front of her so fast. "Those two look heavy. Need some help?" Manami looked at him as if he was some kind of wild animal which could jump on the top of he if it wanted to.

"Um, o-okay," Manami said a little bit uncertain.

"Great!" Karma took out the bags from her hands, then grabbed her wrist and started pulling her to the train which had just arrived. "See you tomorrow, Nagisa!" Karma had waved to him before the doors closed.

They were sitting next to each other. Manami was creasing her skirt and did not dare to look into the boy's eyes. Karma was leaning on his knees, bending towards Manami.

"How did you know which is the right train for me?" She asked, squirming in place.

"It was easy. I looked up everyone's datas before I had come to class," he explained. Manami grunted to hide her laughter. Karma frowned.

"I can totally imagine that of someone who was capable of hurting Koro-sensei twice during one day," she turned towards the boy, then gasped. He was so close to her that their noses met. "Karma-kun, back away a little, please."

"Why should I do that?" Karma asked seductively.

Manami rolled her eyes. She poked Karma's nose and pushed him back.

"There, it was not so hard, was it?" Karma growled in fustration. Manami almost petted his hair. He was like an angry little kitty.

When they stepped into Manami's flat, Karma's mouth opened slightly. It was very small – just enough for only one person.

"Where are your parents?" He asked, putting the bags up to the counter.

"They are working abroad," Manami answered. "This apartment is one of our good friends' and she let me to use it. Karma-kun, what are you doing?" Manami asked, staring at Karma suspiciously. Karma was playing with a knife that he pulled out from the knife-rest on the counter. "That is not an anti-Koro-sensei knife."

"I know, but besides the octopus, there are other guys I really want to get rid of!"

"I don't want to be rude, but are you aware of your horns and wiggling tail?"

"Oh, shit!" Karma hissed out. He put the knife down and disappeared from the flat in the blink of an eye.

Manami blinked a few times, looking at the place her guest stood just a few minutes ago.

'What a strange boy!'
