After having shown himself, Mew began to help Korosensei in his lessons. Well the only lessons he could really help with was PE, language (Written) and as a Nurse.
The surprised look on Karasuma and Bitch-sensei's face was amazing. Karasuma facepalmed as Mew could hear him murmur, 'Not another one' to himself.
Hovering in front of the board, Mew began to write down a few lines at a fast pace. The chalk floated around as words of explanation were written below it. Through a skill Mew didn't use often, Telepathy, he explained how some of the words were pronounced. Even if Mew didn't talk, he was till able to aptly voice the right words and vocabulary.
While most of the students were a bit surprised at the strange added teacher, they still learned a lot from Mew-sensei.
As the bell rang, Korosensei opened the door as he collected Mew and they went on a short trip towards New york to get some snacks.
Enjoying their trips, Mew still adapted to the teachers life and graded the homework of the students during flight. Finishing quickly after adding tips and remarks at some answers, Mew handed the papers to Korosensei and they ordered some food for take-away.

When Mew was back, after having enjoyed some snacks, Korosensei went outside to his usual spot to create a few difficult students that needed an extra push.
Mew joined the students during their free time and handed out a few souvenirs, consisting of cheap snacks that were popular in the USA.
While the students enjoyed themselves, Mew was watching Bitch-sensei sneaking up on Korosensei. Her methods hadn't improved much as she was soon walking back on wobbly legs with a healthy blush on her face.
Giggling, Mew played around with the students as he moved the ball they were training with all over the place with psychic. This caused some of the students to try some acrobatic moves as they hit the ball. As an added bonus, every time someone hit the ball, it would change colours. Making it change speeds every now and then, they students were laughing happily as some were chased by the ball while others were chasing it.
The bell rang and the students went back inside as they finished the rest of their day. Every now and then, Nagisa-kun would come play with Mew as Mew added some funny tidbits to Nagisa's note book. They were mostly about Korosensei's hobbies, like bug catching and reading Pervy magazines.
Glad with the addition Nagisa went back and the day ended.
The time moved on pretty fast as the mid-terms had passed, the class not having improved much. Korosensei was saddened by it, but soon became fired up to increase the quality of his teaching and get back at them with the end-term test, styling his teaching to the personal needs of the students.
In the meantime, Mew was starting to get bored again. Like in the pokemon world, Mew had already visited most of the places, from the great wall in China to the Barrier reefs in the ocean.
Deciding on when to move onwards to another interesting place, Mew continued to watch over the kids as they The days were getting closer to the day for the class trip.
