- Most of the names are parodies of various highschool (dorama) animes.
- Namie is based on the famous Japanese female singer, Namie Amuro. The character's appearance is based around the singer's own appearance, who is renowned for wearing short skirts and long boots. Coincidentally, Namie Amuro would later sing for the anime's 14th opening, Fight Together.
- This comic is a parody for Japanese drama "Gokusen" which the main character who is a teacher have to teach the problem students in 3-D class, and she always wear a jersey while teaching.
- When Red Hair Sensei is knocking out the students, he claims his fists hurt the most. The statement means that the reason why his fists hurt the most is because he (as a teacher) has been forced to hit his students.
- The lesson Red Hair Sensei gives the group of students is on how to spell the Jolly Roger (dokuro) in katakana. The students reaction is because this is basic writing skills methods designed for a preschool child.
- Sansuke's complaint against Mihawk was because Mihawk was telling him off for something minor when he should be complaining about the fact he is smoking heavily on school grounds.
- Luffyshirou's bandana reads "Harvady" in Japanese text, the name of the college he working to get into. This is most likely a play on the name "Harvard", a top American college.
- During the JUMP Festa 2008, the Mugiwara High School was acted out. Because Kazuki Yao voice roles both Mr. 2 Bon Kurei and Franky, Kazuki Yao played as Mr. 2 Bon Kurei and Franky's role in the short was left out. Shūichi Ikeda, Shanks' voice actor, was absent for the One Piece stage show so, Oda himself went on stage with a chalkboard while wearing a hot pink wig and introduced himself as "Shanks".
- Franory hair style matches Franky's new hair style after the two year timeskip.
- Zoro's hairstyle is a mohican style. Tora Gari, one of Zoro's most used moves is a pun on a type of mohican haircut and it is likely this is why he was given the style.
