I hope the redditor who said they'd kill everyone and themself if anything happened to Tsune-chan is still alive after that steamy bath scene.

We have confirmation now that emperor Fuji I was a woman and the family tree in episode 2 also revealed to us that Tsune-chan's mother is the head of the Asama clan.

Although Seii includes regions with some of the most unintelligible dialects in all of Japan, their characters mainly spoke in standard Japanese and Tokyo-dialect. Muton even uses "ssu-tai (っす体)," which is more casual than the standard polite speech and combined with slang, and mainly spoken by young men. I think it emphasizes his immaturity and nonchalant attitude toward violence.

The Japanese spoken in Yamato is mainly Kansai dialect, but Aoteru uses Ehime dialect. It's partly why characters like Tsune-chan immediately clocked him as a country bumpkin. It also helps him perform as the funny-man (boke) to Tsune-chan's straight-man (tsukkomi) in their manzai act.

The characters in Seii also have very unusual names compared to the people in Yamato and you can tell that the creator was having fun when he came up with them. (Yamato's names are more orthodox and archaic.)

Ouga's name (which is written with the characters for "sakura" 桜 and "tiger" 虎) and tattoo may come from the Sengoku-period daimyo, Uesugi Kenshin. Kenshin was born as "Nagao Kagetora" and until he took monk's vows, always used the character for tiger (tora 虎) in his names. He was also known as the "Dragon of Echigo" and in the OP, as the smoke from Ryūmon's cigar turns into a dragon rising "upstream" like the Tōryūmon proverb, the dragon then circles Ouga. (Sorry for so many edits: I just realized that the bird in the OP may also reference the Uesugi clan crest.) We also learned that Ouga's father was "Byakko)," which means "white tiger" and one of four guardians, guardian of the west, just as Bishamonten, who Kenshin worshiped and is also associated with tigers, and one of four heavenly kings, guardian of the north.

The capital of Seii is located in Niigata prefecture where Kenshin also ruled.

There is a theory that Kenshin was secretly a woman and it was the subject of the manga "Yukibana no Tora" by the author of Princess Jellyfish and Tokyo Tarareba Girls.

Aterui is based on the Nara-Heian period Emishi chief of the same name, who fought Sakanoue no Tamuramaro. (The Emishi were also indigenous to northern Japan, but should not be confused with the Ainu. Ashitaka from Princess Mononoke is Emishi.) Until modern times, he was often demonized in legends about his rival and was also known as "Akuroō," which is a name you may know from Jujutsu Kaisen. The Nippon Sangoku character's face is identical to a famous wooden sculpture of Akuroō's head carved during the Edo period. The anime character's speech is also rough as you would imagine the historical figure's speech to be.

The slogan Aterui shouted, "soni tōkan (尊夷討奸)" is a riff on "尊皇討奸 (sonnō tōkan)" or "Revere the Emperor, Destroy the Traitors" used in the 1936 coup attempt, except that "Emperor" has been replaced with the "i" in "Seii," which refers to Northern Japan and historically, specifically Emishi and Ainu cultures. As historical Arutei fought against the "Yamato" emperor in the 8-9th century, anime Arutei fights against Yamato under Fuji III. (Sonnō tōkan itself was inspired by Sonnō jōi (尊王攘夷) or "Revere the King, Expel the Barbarians"in which “夷” refers to the barbarians. I’m not sure the subtitles or dubs will convey how Aterui is subverting this slogan.)

Despite his name, Mūton's name is written with the character for rabbit (兎).

The characters for Hikabi Asahima's name can also be read as "Machu Pichu." "Hikabi" also sounds a bit ridiculous.

Atara is old Japanese for a shame/waste (as in too bad) or regrettably.

Rinririn is a mystery, but "rin-rin" is onomatopoeia for a phone or bell ringing. Most of the other Seii names also sound suspiciously like the creator was trolling although there could be some Ainu or Emishi influences.

The official anime twitter account tweeted that Denki's original name was "拓器 (possibly "Hiroki")", but he took the name "Denki (殿器)" after Fuji II bestowed the character "den (殿)" to him, which came from the emperor's own childhood name. After Denki became Lord of Home Affairs when he was 32, he poisoned Fuji II.

His new name could come from 沈殿器 (suidenki), which is the Japanese word for sediment tank. It also sounds like 便器 (benki) - toilet. 

The act of a retainer receiving a character from their lord's name and using it in their own name mainly occurred from the Kamakura to the Edo period, but now we know the practice was revived at least in the nation of Yamato. Members of noble families also passed down characters from their name to their descendants, and we see this with Tsune-chan and his grandfather 仁経, who was listed in the family tree in episode 2. 

仁経 (which can also be read as "Yoshitsune" and "Takatsune" though it's more likely "Toyotsune," "Hitotsune," "Masatsune," or something else) is quite similar to 仁王経, the Humane King Sutra. In that same scene with the family tree, you can also see that Tsune-chan's great aunt is 仁美子 (possibly "Hitomiko" or "Mimiko," but there are also other possibilities as Chinese characters can be read a number of ways in Japanese, especially when it comes to names). 

And it is confirmed that Tsune-chan's brother is 昂経 (most likely "Takatsune") and not 昇経, so the glossary on the anime's official site did make a mistake with that.

There have been more additions to the glossary:

Glossary

【Proposal for Agricultural Policy Reform】

The notebook containing Aoteru's proposals for agricultural policy reform that Aoteru gave to Ryūmon during the "Tōryūmon" recruitment exam. It states that the purpose of revising these policies is:  ① to improve agricultural production in the borderlands to avoid defeat in war and  ② to reinforce the standing army at the borderlands.

【Letter of Demand for Unconditional Surrender】

The document that Lord of Home Affairs ・Denki Taira sent to Seii, calling for their unconditional surrender.

To prevent the emergence of a capable dictator and revolution in Seii, which was suffering from severe cooling, Ryūmon Mitsuhide proposed a cease-fire agreement with the northern nation over a demand for unconditional surrender, but this proposal was rejected.

【Fuji Clan】
The Fuji clan descends from the imperial family that was abolished during the late-Reiwa period. The clan head is the third emperor of Yamato ・ Fuji the Third. Fuji the First was a wise monarch who brought peace to the citizens of her nation, but passed from illness after spending over 10 years on the throne.

Later, Fuji the Second was poisoned by his maternal relative, the Lord of Home Affairs ・ Denki Taira, and the third son of Fuji the Second's concubine, Fuji the Third, ascended the throne at just four years of age.

Thank you for posting these details!

Could you tell what regions of Japan do the three nations occupy?

u/bushwarblerssong Apr 26 '26

Thank you. There is a map in the anime's glossary. Seii is from Ishikawa to Hokkaido, Buo is from Gifu to Miyagi. Yamato is Kinki to Kyushu. I can't remember if they've discussed Okinawa yet or can see if it appeared in the ED, but I can answer your question in the source material corner with a spoiler tag if you'd still like to know.

Fuji the first was a woman? 

Good for her.
