⚡ Quick Answer
Episode 3 of Seitokai ni mo Ana wa Aru (Even the Student Council Has Its Holes!) aired October 17, 2026. Its jokes lean on Japanese culture: maguro is slang for a passive partner, a breath mint is mistaken for medicine, and Ume's sister's name, pine, outranks his, plum. OceanVeil streams it weekly.
What Happens in Seitokai ni mo Ana wa Aru Episode 3?
The episode opens with the student council cleaning the school pool alongside the swim club. That setup lets the animators show off, and fans in the Reddit episode thread praised the animation quality. Next, protagonist Ume Mizunoe visits Tan Otori, the council's junior high PR officer, who is home with a fever. Ume tries to give Tan a fever suppository, but the box on the floor held breath mints, and the mix-up is the biggest laugh of the week.
After that, the council tutors Ume for exams, with each member covering the subject they know best. The episode closes when Ume's older sister arrives, and she turns out to be a devoted fan of her little brother.
| Scene | The real detail behind the joke |
|---|---|
| Swim club introduction | Maguro (tuna) is also Japanese slang, and a calf muscle carries a fish name |
| Sick visit at Tan's home | Suppositories are genuine medicine for people who cannot swallow pills |
| Ume's sister arrives | Pine and plum are two thirds of a classic Japanese ranking trio |
What Does Maguro Mean in Seitokai ni mo Ana wa Aru Episode 3?
A swim club member asks to be called Maguro, which literally means tuna. In Japanese slang, the word also describes a passive, unresponsive partner in intimate settings, and the metaphor is a tuna lying motionless once it is out of the water, as the pixiv dictionary explains. English has a close match in "dead fish". Fans in the thread noted that Ume reacts to the nickname because he knows the slang, which tells you the show expects viewers to catch it.

The fish theme does not stop there. She points at her calf and boasts about it, and a fan in the r/anime episode discussion explained the second pun. The calf muscle is the soleus, which Japanese calls hirame-kin, literally "flatfish muscle". So a girl named after tuna brags about a flounder, and the joke only lands if you know both words. The English name has a quieter origin: "soleus" comes from the Latin word for sandal, according to Wikipedia. The muscle lifts the foot and is vital for walking, running and balance, so it is a sensible thing to brag about.
Why Is Ume's Sister Named After a Pine Tree?
Subtitles disagree on the name of Ume's sister. Some give Matsu, while a commenter says the correct reading is Shou. Both come from the same kanji, 松, which means pine. Ume's own name is the kanji for plum, and that pairing is not an accident.
Pine, bamboo and plum form the Three Friends of Winter, a trio that Japan calls shōchikubai. It appears on New Year greeting cards and seasonal sweets, and it is sometimes used as a three tier ranking, with pine on top, bamboo in the middle and plum at the bottom, per Wikipedia. Here is my read, and it is a reading, not something the show confirms: the sister's name outranks her brother's, which suits a character who treats him like a treasure and a toy at the same time. One viewer already wonders whether a bamboo sibling is coming.
📊 Key Stat: The manga has run in Weekly Shōnen Magazine since April 27, 2022, and had reached 13 volumes in Japan by August 17, 2026, according to Wikipedia. The anime adapts that four panel comedy over 12 episodes.
Are Suppositories Real? The Medicine Behind the Mint Mix-Up
Yes, suppositories are real medicine, and the gag only works because viewers know that. They are described as ideal for infants, elderly people and post-operative patients who cannot swallow oral medication, and they help people with severe nausea or vomiting because nothing has to be swallowed, per Wikipedia's suppository entry. The same entry says the rectal route can reduce the time a drug takes to act.
A fan in the thread said Japanese parents commonly use fever suppositories for small children. I could not confirm that with a source, so treat it as a fan remark.
⚠️ Important: The mix-up is slapstick, not advice. Never put candy or any non-medical item in your body as a substitute for medicine. If you are unsure which product to use, ask a pharmacist.

Why Does Seitokai ni mo Ana wa Aru Episode 3 Work So Well?
When the mint reveal landed, I paused the episode just to catch my breath, and then I went hunting for the Japanese wordplay I had missed. That is my honest takeaway from this episode: the jokes work on two levels. If you miss the reference, the scene is still a fast, well timed gag. If you catch it, you get a second joke on top, and the fish puns and the pine and plum naming are exactly that kind of layered writing.
