Miss Machiko and her Class
Miss Machiko / Machiko Mai
The main protagonist of the series. Mai Machiko is a 24 year old college graduate who works as a science teacher at Arama Middle School. Despite her qualifications, she frequently finds herself on the receiving end of perversion from students and staff alike. Yet she always tries to be the best she can be for her young students.
- 100% Adoration Rating: Good luck finding a single person who doesn't like her. Although this does tend to work against her as it attracts many unwanted suitors.
- The Ace: Machiko is not just a teacher. She can act, dance, sing, fight, swim, pick up any random skill on a dime and is otherwise perfect aside from her inability to keep dressed.
- Action Girl: Machiko is a martial artist who can beat down packs of dogs, and several men larger than herself at once.
- Adaptation Dye-Job: Machiko was blonde in the original manga. In the anime, she's a brunette. This has become Ret-Canon, as the Manga's original creator drew her this way for a collaboration with a Mobage game.
- Adaptation Personality Change: In the original Manga, Machiko was none too happy with her students' rowdy behavior, to the point where she would (quite justifiably) fly into rages and beat the stuffings out of them - especially Kenta. By contrast, in the anime adaptation, she makes it explicitly clear that she doesn't at all mind "hanky-panky pranks and rowdy behavior".note In the third episode, when she ends up with an unintentional case of Absolute Cleavage on the school's internal communications TV, she responds with a cute smile and a pose, like it's no big thing.
- Bathing Beauty: Machiko enjoys it when she takes a shower. So do the other characters.
- Bathtub Bonding: She did it with Mr. Yamagata's elderly mother in one episode. Somehow she still ended up getting touched in a way she didn't want to.
- Beware the Nice Ones: She can throw down when she needs to.
- One example being when she saves her uncle from a guest that was taking a friendly duel too far.
- Special mention goes to the final episode, where in response to a particularly cruel and mean-spirited prank Kenta played on a new student, Miss Machiko delivered a devastating slap that sent him flying nearly ten feet away.
- Brainy Brunette: She is a science teacher.
- Butt-Monkey: If you consider constantly being constantly sexually harassed and stripped by minors to be in line with this. Although she does partake in Slapstick every once in a while.
- Buxom Is Better: She is specifically noted as having large and attractive breasts.
- Catchphrase: "I give up! / shame!". And it comes with a cute pose.
- The Chew Toy: Since most of her misfortunes are played for Fanservice, she counts.
- Dude Magnet: Gains the affection of over five one shot characters, and her students and fellow teachers are constantly competing for her heart.
- Clothing Damage: This happens to her a lot. Depending on which would be funnier at the time, her clothes range from being durable enough to be physically suspended from, to being torn like rice paper by her own movement.
- Cosmic Plaything: The universe itself must like seeing her out of her clothes, because she will end up nude by random happenstance if no one else gets to her first. This can range from her skirt getting torn off by a tree branch to being intentionally molested by various wildlife.
- Ditzy Genius: Miss Machiko has shades of this.
- She doesn't always catch on that some characters want her. And while they usually catch her off guard, Miss Machiko can't always see what's obviously a ploy for Kenta to get in a touch.
- Miss Machiko can even behave in a clueless manner when involving non pervy stuff. She can be easily distracted by someone telling her there's a UFO in another direction. And one time she almost left the house wearing nothing but a towel.

- Episode 73 has Machiko set Kenta up to be spanked in front of an audience of people.
- Girly Bruiser: She has knocked out men much larger than her with standard effort.
- Girly Girl with a Tomboy Streak: She loves and participates in all kinds of sports, knows martial arts, and generally keeps herself extremely fit. She also has no problem at all appearing in extremely feminine outfits or generally acting in traditionally feminine roles.
- Going Commando: She always wears panties, but she only ever wears a bra half of the time.
- Guile Hero: She's not above using trickery to solve a problem. Such as when she gives a mad scientist a supposed youth potion that is actually a bottle of soda. Then there's how she deals with Kenta.
- Hartman Hips: She has large ones. Kenta claims that she sways them back and fourth when she walks.
- Instant Expert: She picked up skateboarding quickly after falling once.
- It's All My Fault: She blames herself more often then not when her students misbehave.
- Ms. Fanservice: This woman can probably check off over 90% of the fanservice tropes on this site. And she isn't even trying to.
- Hot Teacher: Everyone is attracted to her at least a little bit, which is why no one stops her students' pranks. That, and the very universe conspires to have her denuded, so any such efforts would be futile.

- Modesty Towel: Although they fall off nine out of ten times she wears one.
- Naked Freak-Out: Whenever Miss Machiko is stripped bare in public, this is her reaction.

- Red/Green Contrast: Red and green are the colors of Machiko's primary outfit, and Machiko herself is passionate and levelheaded.
- Reluctant Fanservice Girl: She constantly loses her clothing in the most blatantly ridiculous ways imaginable. She doesn't intend for any of this to happen - half of the people around her and the universe itself all want her disrobed.note
- Singing in the Shower: She likes to do this. She even does this in her theme song.
- Shower of Awkward: She's been walked in on while showering too many times to count.

- Wardrobe Malfunction: How could this not happen?
- Wide-Eyed Idealist: Some characters, especially the Vice Principal believe Miss Machiko's idealistic beliefs get in the way of her properly disciplining her students. She insists Kenta and his friends are nice boys even though their other victims say otherwise.

- You're Cute When You're Angry: She is. The end credits song says so.

- Class Clown: He's the one causing mischief.
- Determinator: Nothing will stop this boy from sexually harassing Miss Machiko. Nothing.
- Dirty Kid: All of the boys fit this trope but particularly Kenta, who is often the ringleader of the boys and works out several plots to grope, disrobe, or otherwise act pervy to Miss Machiko (or his female classmates). While his comrades have some standards, Kenta lives just to sexually harass every cute female in the show with Machiko as primary objective. He's basically a young Ataru with Goku's voice.
- Easily Forgiven: Miss Machiko sees his attempts to humiliate her as a sign of affection, and only very rarely takes any punitive action against him. That said, even a Nice Girl like Machiko has a limit to what she will tolerate.
- Everyone Has Standards: Kenta draws the line at blackmail. He also doesn't physically abuse anyone for his own amusement unlike Genchiki.
- Jerk with a Heart of Gold: Kenta very occasionally demonstrates that he has the potential to be a good boy. Such as when the vice principal was getting ready to transfer to a different school, and Kenta was the primary force trying to prevent it by behaving like a proper student.
- Karma Houdini
- Lovable Sex Maniac: He certainly fits the trope. If he finds a girl attractive, he'll definitely show it by molesting her in some way.

- My God, What Have I Done?: Kenta will feel regret for his actions when his pranks go too far. Most of the time anyway.

- Schemer: He is the creator of many elaborate plans, all for the sake of violating his poor teacher.
- Skinship Grope: He takes a bath with Miss Machiko in episode 68, and wastes no time putting his hands on her breasts as the chance came.

One of Kenta's two friends.

And judging by their report cards, Kame get's higher grades than Kenta more often.
- Vitriolic Best Buds: With Kenta. He occasionally insults Kenta, and the two strike each other from time to time. But they always put their differences aside for the sake of humiliating Miss Machiko.

- Eyes Always Closed: Usually. But when they aren't it's hard to tell anyway.
- Hypocrite: She's actually severely disappointed with the fact that an unknown Chikan doesn't grope her on the bus - he's always going for someone else instead because her bust is so small.

- Fan Disservice: In-universe, the boys don't find her attractive.
- Hair-Trigger Temper: All it takes is a comment against Maruko's weight to get her after you.
- Mood-Swinger: In episode 51, Maruko was relieved and brought to tears at first when she learned that Kenta only faked an illness so he could partner up with Miss Machiko instead of her. She then became angry and chased him across the field. After they won the relay race, she celebrated with Kenta, then went right back to chasing him.

An early example being when Hiroshi made Miss Machiko a leotard that was designed to tear itself apart at the highest setting, then gave the remote to Kenta. When Machiko was inevitably stripped bare, Hiroshi shone a strobe light on her as she was begging him to stop, which left her open to get touched by Kenta. All of this took place in front of a large audience of people. Hiroshi doesn't pull his punches.

- Cool Car: A nice red one, in contrast to Mr. Yamagata's
- Foil: To Mr. Yamagata. Both are in love with Miss Machiko, but Yamagata is far more eccentric with his advances, always being clear with his intentions, while Kagoshima is more restrained and subtle. Both have the potential for perversion, but Kagoshima won't cross most lines that Yamagata would. And both are teachers, but Kagoshima is tall, economically secure and respected by his students, while Yamagata is short, lives in a single room apartment, and gets no respect from anyone, except Machiko.
