It has been several years since Koro Sensei was assassinated, and Nagisa and some of the others were visiting his grave.

"Come on, Kaede, we're going to leave you behind," said Nagisa as he stood with Akari.

"Sorry, dad," said a thirteen-year-old girl with Nagisa's hair and Akari's eye colors as she ran up.

"I was picking some flowers for Korosensei's grave," said Kaede as she showed them some yellow flowers.

"That damn octopus would like those," said Karma as he walked up in a suit. Walking beside him was a boy Kaede's age who looked like Karma.

"Hi Mr. Akabane and Chūsei," said Kaede with a smile.

"Hey Kaede, you like flowers more than training or what?" asked Chūsei with an obnoxious smile.

"You're going to regret saying that," said Kaede as she gave Akari the flowers.

"I think we should let these two duke it out," said Akari as her daughter tried landing a kick to Chūsei's side.

"Yeah," said both Nagisa and Karma as Chūsei put Kaede in a headlock. As their parents went on, Kaede got out of the headlock by hitting Chūsei in the face with the back of her head. A few hours later, the two had shown up at the grave sight, cuts and bruises all over them.

"I can't believe you two did this to yourselves," said a girl with white hair as she put bandages on them.

"You should have seen her new technique, Supāku," said Chūsei as he rubbed the left side of his neck.

"What new technique?" asked a boy with orange hair.

"I'll show you, Kaze," said Kaede as she stood up and started walking toward him. Suddenly, she got behind Kaze and took him down to his knees with a pinch to the left side of his throat.

"Whoa," said a girl who looked like Ritsu. Kaede then released her grip.

"I spent the last three summers training with Mr. Karasuma to get my grip strength up," said Kaede. Meanwhile, Nagisa and the other parents were talking.

"I can't believe you actually let her train with Tadaomi for three years," said Itona.

"And what did she do to get that strong of a grip?" asked Ritsu who was on a tablet.

"She did the same four excersises everyday," said Akari.

"She just hung from a pull up bar, did several farmer's carries, towel pull ups, and broke her fingers on cement walls," said Nagisa.

"Wait, she broke her fingers everyday?" asked Itona.

"The government made a new healing chamber that can heal any non-lethal wound," said Akari.

"That's cool," said Ritsu.

"I can't believe she trained in a way like the Tiger Claw, that's one of the most dangerous fighting techniques," said Karma.

"She also named it the Snake Bite since it only uses two fingers on a pressure point," said Nagisa.

"That's a pretty deadly move, if your opponent is human that is," said a voice from above them. When everyone looked up, they noticed a black version of Korosensei on the roof.

"Is that you, Korosensei?!" asked Nagisa with a stunned expression.

"Oh, I'm more deadly than that fool!" said the creature before vanishing. Suddenly, a mountain was destroyed a seconds before he returned.

"No way," said Kaede as everyone stared at the destruction with fear filled expressions.
