It has been a week since their Sensei joined them. Every day was the same. Learning, attempts of assassinations, there was barely a change. The students of Class E were already on the verge of giving up, deeming the task of killing their octopus-sensei impossible. The only thing urging them to continue was the prize.
After another failed attempt at assassination by another student, a group of students decided to meet up with his sensei after class, Nagisa following along in hopes to gather more information regarding their sensei.
They were being tutored by him, a learning session they requested. After numerous tries, their efforts were proving to be fruitless.
Kaede sighed, "How about we try a different approach?"
Nakamura shrugged, playing with the idea in her head before deciding to go with it. There's no harm in trying, after all. "Sensei!" She caller for their tentacled-teacher's attention. Said person paused from grading their tests, tentacle holding a marker paused mid-air. He raised his head, and she took it as a sign to continue. "What's your greatest weakness?"
The other students were doubtful of the idea, but thought it was worth a try. Koro-sensei stood still for a few moments, the students didn't even bother trying to harm him. They were holding their breaths in anticipation. After a few moments, just as they were slowly taking out their guns and knives, their teacher turned an interesting shade of red-pink. The red color a clear sign that he was angry, but the mixture of pink was new.
A new shade! They all mused. Nagisa wrote it down on the notepad he always had in hand just in case something related to their teacher comes up, like the current time. 'What could this color mean?' They all thought, before realizing Koro-sensei was acting weirdly.
They all watched him as he rubbed his tentacles on his face, an action almost alike to a person getting irritated. "Ninjas." He replied, dodging a bb bullet and a swipe of a rubber knife.
The students glanced at each other in question, before turning back to their sensei. "Nin..jas?" They repeated in unison. He told them one of his weaknesses willingly, but it was as if he was playing with them. Ninjas don't exist! But his tone suggested otherwise, they didn't know what to believe.
Koro-sensei seemed to have calmed down, tentacles rested on his desk. The group of students decided to listen, pausing their advances. "I won't tell you much," Green stripes appeared on his face, "That's the only information I allowed myself to tell the government, too."
The team sighed, exasperated. So much for asking.
"Is it a person?" Nagisa suddenly asked, thinking of all the possible meanings of "Ninjas". Such knowledge was valuable, it could aid them in their quest. The opportunity was too important to pass up. It could be a code name of something, an alias of someone.
Koro-sensei nodded, the weird shade of red-pink back on his face. 'He doesn't seem to be bothered by admitting things.' They deadpanned. Nagisa wrote a question mark beside the new information on his notepad, still unsure of what it meant.
"Three people, to be exact. But Pinky is my favorite."
