Free Assassination Classroom Coloring Pages: 50+ printable PDF pages featuring Koro-sensei, Nagisa Shiota, Karma Akabane, Kaede Kayano, the rest of Class 3-E, plus cute and chibi designs. All free, download PDF to print, or color online.
What makes these pages different from a normal anime set is Koro-sensei himself. His big, round face is famous for changing color to show his mood, bright yellow most of the time, red when he is angry, and other shades and markings for other feelings. That turns a single character into an open-ended coloring exercise: the same smiling face can be colored a dozen ways depending on the emotion you want to show.
Assassination Classroom (Ansatsu Kyoushitsu) is a manga by Yusei Matsui, later made into a popular anime. It follows Class 3-E, a group of students given an unusual assignment by a strange, super-powered teacher they nickname Koro-sensei, fast enough that he is almost impossible to catch. Under the comedy and the wild premise, it is really a warm story about a class and the teacher who believes in them, which is why the cast is such a fun mix to color.
Younger fans can begin with the cute and chibi pages and simple single-character portraits. Older kids, teens, and anime fans can take on Koro-sensei’s expressive faces, detailed student portraits, and full Class 3-E group scenes. These pages suit a range of ages and skill levels and work at home or in the classroom. They are fan coloring activities and are not official anime stills, manga panels, posters, merchandise, or endorsed Assassination Classroom products.

What is Inside Assassination Classroom Coloring Pages
Koro-sensei Coloring Pages
Koro-sensei is the centerpiece of the collection and the most fun to experiment with. His design is simple to recognize: a big round head with a wide grin, two small dot eyes, a graduation cap, and a flowing academic gown, but his color is anything but fixed.
This is where these pages stand out. Because his face changes color with his mood in the series, you can color the same portrait yellow for his usual cheer, red for anger, or a paler shade for shock, and even add the small stripes and marks he shows when he is grading or pleased. One outline becomes many different pages.
These designs work well for mood charts, classroom displays, and fan cards, and they are a great choice for colorists who want to play with color rather than copy a fixed palette.
Coloring Koro-sensei pages: Decide on the mood first, then pick the face color to match, keep the gown a deep solid tone, and leave the grin and cap crisp so the cheerful shape still reads.
Nagisa Shiota Coloring Pages
Nagisa is the quiet, observant lead of Class 3-E, and his portraits are a calm, approachable place to start. He has pale blue hair tied in two low pigtails, blue eyes, and a neat school uniform.
His palette is gentle and limited, which makes him good for practicing soft, even color and clean lines. The blue hair is his anchor; keep it light with a slightly deeper blue for shadow so it does not go flat.
These pages are useful for character cards, fan-folder covers, and simple portrait practice, and they pair naturally with Karma in the many two-character pages.
Coloring Nagisa pages: Keep the blue hair light with one deeper shade for shadow, color the uniform in calm neutrals, and let his soft expression carry the page.
Karma Akabane Coloring Pages
Karma is Nagisa’s sharp, mischievous classmate, and his pages bring the boldest student palette. He has bright red hair, keen eyes, and a confident smirk, often with his uniform worn loosely.
The red hair is the star here. Layer it from a lighter scarlet to a deeper crimson so it looks rich, and keep his expression a touch playful, since that attitude is a big part of the character.
These pages suit colorists who like a stronger, warmer palette and a small quantity of personality in the face, and they balance well against Nagisa’s cooler tones in shared scenes.
Coloring Karma pages: Build the red hair from scarlet to crimson, keep the eyes sharp, and let a slight smirk give the page its character.
Kaede Kayano Coloring Pages
Kayano is one of the brightest, friendliest faces in the class, and her pages are light and cheerful. She has green hair in short twin pigtails, green eyes, and a small, lively look. Some pages list her under her other name, Akari Yukimura.
Her green palette is distinctive and easy to keep consistent: a fresh, slightly soft green for the hair, with clean highlights. A warm, simple background keeps the page cheerful without competing with her.
These pages are a good fit for younger fans and for anyone who wants a friendly, easy character to color.
Coloring Kayano pages: Use a fresh green for the hair and eyes, keep highlights clean, and choose a light background so her cheerful look stays the focus.
Itona Horibe Coloring Pages
Itona is the calm, stoic classmate, and his pages are good for a more minimal palette. He has short, pale hair in a blunt bowl cut and a flat, composed expression.
Because his look is understated, these pages reward careful, even coloring rather than bold contrast. Keep the pale hair soft and let small shading choices on the face do the work.
These designs are a nice change of pace for colorists who like quieter characters and clean, simple shapes.
Coloring Itona pages: Keep the pale hair soft and even, use light shadows on the face, and avoid heavy contrast so his calm look stays intact.
Class 3-E and Group Coloring Pages
Group pages bring the class together, and pairings such as Nagisa with Karma, or Koro-sensei with his students, are some of the most rewarding designs. This part of the collection also includes other class members and the teachers, Irina and Karasuma.
The challenge is keeping a row of students clearly distinct while the scene still feels like one class. Give each character their signature hair color, then use a single classroom or outdoor background tone to tie the group together. Fans of this classroom cast may also like My Hero Academia coloring pages, another anime built around a school class.
These pages are ideal for roster posters, fan-folder covers, and display pieces that show the whole of Class 3-E.
Coloring group pages: Color each student in their own hair color first, then add one shared background tone so the class reads as a group instead of separate figures.
Cute and Chibi Coloring Pages
The cute and chibi pages, including chibi versions of Nagisa and other characters, are the easiest designs for younger fans or short sessions. They simplify each character into rounder shapes and bigger features, so the signature colors still read clearly with less detail.
Use softer, slightly brighter versions of each palette and keep backgrounds simple. These pages also make great mini cards, stickers, and bookmarks.
This group is the most beginner-friendly part of the collection and a gentle introduction to the cast.
Coloring cute and chibi pages: Use larger color blocks, shiny eyes, and soft features, keeping each character’s signature color so a chibi Nagisa still reads as Nagisa.

What These Pages Do
Assassination Classroom is, at its heart, a story about a classroom, so it is fitting that coloring these pages is itself a small learning activity. Staying inside the lines of a character, choosing colors, and planning a busy group scene all ask for the kind of focus and hand control that schoolwork relies on.
That link is well-documented. In a study published in Child Development, Fine Motor Skills and Executive Function Both Contribute to Kindergarten Achievement (Cameron et al., 2012), researchers found that young children’s fine motor skills, especially copying shapes and designs, along with executive function, predicted later academic achievement. Coloring within outlines is exactly that kind of visuo-motor practice, dressed up as play.
There is a calmer side, too. In a randomized study in the Creativity Research Journal, Sharpen Your Pencils (Flett et al., 2017), participants who colored daily for a week reported lower anxiety and fewer depressive symptoms than a comparison group doing puzzles. These pages are not a replacement for support or therapy, but a defined character page, with clear outlines and a familiar cast to aim for, that gives a colorist an easy, low-pressure place to focus.
What makes this set genuinely different is Koro-sensei. Most coloring subjects have one correct palette; he does not. Because his face color signals his feelings, a single portrait becomes a small lesson in matching color to emotion; color it yellow, red, or pale, and the same drawing tells a different story. That is an unusual amount of creative range for one character.
Small details such as Koro-sensei’s tentacles and gown, the students’ varied hairstyles, and the faces and uniforms across a group page give children plenty of room to practice patience, pencil control, and color planning.
How to Color Assassination Classroom Coloring Pages
Each character section above gives you a palette to aim for. Here is the order that keeps a page clean once you start, whether it is a single portrait or a busy Class 3-E scene.
Start with Koro-sensei’s face color, because it sets the mood. On any page with him, decide the emotion first and pick the face color to match. Everything else is easier once his mood is set.
Block in the big shapes before the small ones. Lay out the large areas, the gown, hair, and uniforms, before touching fine details. This keeps the page even and gives you room to build contrast.
Give each student their hair color as an anchor – Blue for Nagisa, red for Karma, green for Kayano, and pale for Itona. Locking in hair color early makes a busy class page much easier to read.
Save the fine lines for last. Color the grins, eyes, tentacle tips, and uniform details once the base colors are settled, so small marks sit cleanly on top.
For group pages, pick one classroom background tone. A single shared background, a wall, a sky, or a chalkboard green, ties the whole class together while the separate palettes keep each character distinct.
Finish with a label or caption. Add a short original caption, such as “Class 3-E” or a mood word for Koro-sensei. This works well for portraits, group scenes, and fan-folder displays.
5 Creative Craft Ideas with Assassination Classroom Coloring Pages
Koro-sensei Mood Chart
Print several copies of the same Koro-sensei portrait. Color each one a different face color to match a different mood: yellow for happy, red for angry, pale for surprised, and so on.
Arrange the finished faces on a board and label each with the feeling it shows. It makes a fun emotions poster that uses the character’s real color-changing trick.
Class 3-E Roster Poster
Print single-character pages for as many students as you like and color each in their signature palette. Keep the backgrounds consistent.
Line the finished portraits up on a poster board with a name under each, like a class photo for Class 3-E.
Character Bookmark Set
Print cute, chibi, or simple portrait pages and color the hair and faces carefully. Cut each into a bookmark shape.
Make one bookmark per character so the set covers the class, and add a small name label to each.
Expression Card Set
Print a few character pages and color each with a different mood in mind, using brighter or cooler shading to match. Koro-sensei is perfect for this because of his face color.
Turn each into a small card with a one-word caption like “Cheer” or “Oops,” and use them as reaction cards or notes.
Anime Fan Folder Cover
Print a clean group page or a favorite character portrait and color it with a balanced palette.
Glue the finished page onto a folder, add a label such as “Assassination Classroom” or “Anime Notes,” and use it to store your other finished anime coloring pages.
