[Demon Slayer] Anime Original Theory Part 3: The "Shinjuro Rengoku = Michael" Theory and the "Ruka = Joan of Arc" Theory 👼

Hello, I am a nameless shepherd Ꮚ˙ꈊ˙Ꮚ
Even though I say I'm watching the recordings to write these theories, I find myself swooning over Rengoku-san and his father every single time _:(´ཀ`」 ∠):_✨
It really makes me feel young again... I am grateful 🙏💕

Now then, last time I explained Kyojuro Rengoku's action of sheathing his sword from the perspective of a wish for the end of the COVID-19 pandemic 👼✨✨

This time, I would like to put the spotlight on his father, Shinjuro Rengoku, and his mother, Ruka Rengoku, who were synchronized with that action 🍀

Deducing from the anime-original demon who is Gilles de Rais 💡
"The Shinjuro Rengoku = Michael Theory 👼"

Last time, I analyzed the action of sheathing the sword with the theme of "a wish for the end of the COVID-19 pandemic based on tradition," so this time I would like to explore other meanings contained in this scene 🐏💡

To repeat, this scene is depicted with Kyojuro Rengoku synchronizing with the past actions of his father, Shinjuro Rengoku 👀

I believe this is a manifestation of Kyojuro's heartfelt respect for his father, and at the same time, it symbolically signifies that Kyojuro Rengoku = Shinjuro Rengoku 🔑

In other words...

"Kyojuro Rengoku = Shinjuro Rengoku = Archangel Michael 👼"
I think this equation holds true 📝

I revealed that the anime-original demonfrom the previous theory who resembles Akaza was the former ally of the saint Joan of Arc, Count Gilles de Rais ⚔

The country of "France" was presented as a major hint by this anime-original demon 🍞💡

So, let's search for a place deeply connected to these three keywords: "Kyojuro Rengoku (Michael)," "Gilles de Rais," and "France" 🔍

It is the World Heritage site that France boasts, "Mont Saint-Michel" ⛪✨✨

As the name suggests, it is crowned with Saint Michel (Michael), and it began when the Archangel Michael ordered Bishop Aubert of Avranches to "build a sanctuary on this rocky mountain," and it was built 👼

And during the Hundred Years' War when Joan and Gilles were alive, Mont Saint-Michel was apparently used as a fortress 🏰

The basis for the Archangel Michael of Mont Saint-Michel and Shinjuro Rengoku ⛪

My first impression after reading the episode of the Archangel Michael of Mont Saint-Michel was "a bit scary 😨" 💦

The slightly scary episode is as follows ☟

The Archangel Michael gave Bishop Aubert of Avranches a divine revelation in a dream to "build a sanctuary on this rocky mountain," but he thought it was a prank by the devil and did not believe it. He had the same dream a second time, but still did not believe it. On the third time, the Archangel lost patience, touched the bishop's forehead with his finger, and commanded him strongly, causing Aubert to have a dream where lightning ran through his brain.

The next morning, when Aubert placed his hand on his head, he was stunned to find a hole in his skull, and he became convinced that Michael's revelation was real. He then built the chapel.

Isn't having a hole in your head scary... 😅💦
Since these things are so-called religious "miracles ✨✨," I don't think we should measure them by our own common sense (^^;)

I intuitively thought, maybe this Michael isn't Kyojuro-san...❓
So I checked the original work... 📚

This episode was actually already hidden and incorporated into the original Demon Slayer manga 💡

Around the beginning of the Entertainment District Arc (Chapter 68, "User"), there is a scene where Shinjuro accuses Tanjiro, saying, "You, a user of Sun Breathing, have come to make fools of us, the successors of Flame Breathing 😡."

In this scene, immediately after pointing at Tanjiro, Shinjuro suddenly strikes his head without allowing any argument ✊ 💥

And after the brawl, the final blow was a headbutt where Tanjiro lunged forcefully from the top of his head 🚀🔥
And on the blank page, as if it were an important matter, it is specifically written as a "screw-style headbutt," complete with an illustration and explanation (Volume 8, page 150).

This depiction is surely a hint for the composition of Archangel Michael of Mont Saint-Michel = Shinjuro Rengoku 📝🔥

The "Ruka Rengoku = Joan of Arc" theory derived from Gilles de Rais and Shinjuro Rengoku ✝🔥

When analyzing the anime-original demons, I predicted that Gilles de Rais would be a major hint for Shinjuro Rengoku's past💡

This is because Shinjuro Rengoku has a scene where he tortures (or something similar) the Lower Rank Two demon, Hairo, from the spin-off, and furthermore, he becomes self-destructive and drowns in alcohol after losing his beloved wife, Ruka.🍶

I believe Shinjuro Rengoku is likely a version of Gilles de Rais who has offloaded the negative aspects of perverse sexual desire and child murder onto an anime-original demon.👀💡
It is as if the madness was extracted from Gilles and turned into a demon.🔥


Gilles de Rais became self-destructive after fighting through wars together and losing his beloved Joan of Arc. This is also very similar to the image of Shinjuro, who became self-destructive and drowned in alcohol after losing his beloved wife.

Also, Gilles de Rais was said to be an avid reader, and Shinjuro is depicted impressively reading books(Information provided by a friend🙏✨)📚

What emerges from this is...
Ruka Rengoku = Saint Joan of Arc✝✨

Extracting the grounds for Ruka Rengoku = Saint Joan of Arc👁👁✨

I will extract elements of Joan of Arc based on keywords related to Ruka Rengoku.👀
I will also try to find them from the two highly relevant keywords: Gilles de Rais and Michael.🔍

[Gilles de Rais = Bluebeard]
・The "Ru" in Ruka is Lapis Lazuli (Ruri) color ➡ Lapis Lazuli = Blue
・Yukata in Kyojuro's flashback scene ➡ Blue flower pattern
・Motif of the Rengoku family's wind chime ➡ Blue bellflower (Kikyo)
・The beloved of Shinjuro Rengoku (Gilles de Rais) ➡ Gilles de Rais is the model for Bluebeard
・The Rengoku family seems wealthy ➡ Gilles de Rais was one of the wealthiest men in Europe💰
　　
[Michael]
・Wife of Shinjuro Rengoku (Michael)
　➡ Heard the revelations of Michael and succeeded in liberating Orleans = Destined partner
・Respects Shinjuro Rengoku (Michael)
　➡ Advises Kyojuro (Michael) to become like his father
・The "Ka" (Fire) in Ruka ➡ Michael is the Angel of Fire🔥👼

[Joan of Arc]
・A personality that is resolute and shows no weakness ➡ Brave and Joan-like⚔
・The "Ru" in Ruka is Lapis Lazuli color ➡ Joan's emblem is blue
・The "Ka" in Ruka 　➡ Joan was executed by burning at the stake🔥
・The Rengoku family seems wealthy💰
　　　　➡ Advises Kyojuro not to enrich himself
　　　　➡ Christian teachings (Epistle of James, Chapter 5, Verses 1-6)✝
・Motif of the Rengoku family's wind chime 　
　　　　➡ Japanese band Janne Da Arc "Kaze ni Notte" (Riding the Wind)🎶
　　　　➡ Written by yasu after watching a documentary on the Indian Ocean earthquake
　　　　　　with thoughts of a requiem


Since there is little official information about Ruka-san, it was quite difficult, but I have determined that Ruka Rengoku is Joan of Arc by combining "Gilles de Rais" and "Michael".👀

I was personally surprised that the band Janne Da Arc's "Kaze ni Notte" came up!I don't know the truth of whether this is correct, but since it was created as a requiem, it is a perfect hint.(There are quite a few recent things like this as hints for other characters, so I think it's quite possible🐏💡)
Perhaps Gotouge-sensei is a fan.😊

Saint Joan of Arc and Archangel Michael

Could this be the model for the glowing dwarf Tanjiro saw that the young man with tuberculosis saw on the Mugen Train...?

Joan led France to victory in the Hundred Years' War because she received a revelation from Archangel Michael saying, "Go and save the Kingdom of France. Lift the siege of Orleans."It is said that this is why. The Saint-Pierre Church inside Mont Saint-Michel. There is a statue of Joan of Arc quietly nestled at its entrance.

Joan, who contributed to her motherland and was a hero.

She ended her life with such a young and sad conclusion.
I cannot help but pray that she was welcomed by Michael in heaven.
Could the World Heritage site Mont Saint-Michel be the Rengoku family home where Joan and Michael reside, and a hidden holy land?⛪✨✨

※I am truly grateful to my friend for the information, including the blue bellflower on the Rengoku family's wind chime...(´；ω；`)✨✨
