Hello! This is Osamu, the manga blogger. Demon Slayer  has taken all of Japan by storm. Its appeal, of course, lies in its moving story and fascinating characters. But I believe the root of its horror—and its sorrow—lies in the existence of the "Oni" (demons). They are depicted as transcendent beings who rule the night, devour humans, and possess incredible regenerative abilities. So, are these "Oni" in Demon Slayer  the same as the "Oni" we know from classic folktales (like

Hello, this is Osamu, the Blog Maker. Jujutsu Kaisen  is incredibly popular, isn't it? I'm completely hooked myself. Beyond the intense action, what particularly draws me in is the "depth" of its world-building. Why does this story grip our hearts so fiercely? I believe it's because the series is more than just a battle manga; it stimulates our unconscious, shared memories of ancient "myths" and "sorcery." Today, I want to take a slightly deeper dive into the source of Jujuts

Hello! This is Osamu, the manga blogger. Demon Slayer: Kimetsu no Yaiba ... no matter how many times I read it, my heart burns with excitement. The incredibly unique characters, the life-and-death battles with their nemesis, the demons... And at the core of those battles is, of course, "Total Concentration Breathing." The Demon Slayer Corps members use this special breathing technique to push their physical abilities to the absolute limit and fight on par with demons. It got

Hello! This is Osamu, the manga blogger. Did you get a chance to read my last post about "Breathing Techniques and Shinto Rituals"? Man, the more I dig into Demon Slayer , the more I find it connects to traditional Japanese culture and mythology. I just can't stop analyzing it! So, last time was about "breathing," so this time I want to focus on the "organization" of the Demon Slayer Corps. That's right: the top fighters of the Corps, the "Hashira" (Pillars) . They're explain

Hello! This is Osamu, the manga blogger. He is the origin of all evil in Demon Slayer: Kimetsu no Yaiba , and the ultimate nemesis: Muzan Kibutsuji. In the story, it’s revealed that he was born as the progenitor of the "Oni" (demons) over a thousand years ago, during the "Heian period." Doesn't that make you wonder? Why the Heian period? Not the Warring States (Sengoku) period, nor the Edo period. At first glance, it seems like a glamorous era where aristocrats cultivated ele

Hey everyone, it's Osamu. Thanks to a certain incredibly popular manga and anime, the idea that "wisteria flowers repel demons (Oni)" has become common knowledge lately. In the story, wisteria is used like a protective barrier to keep demons at bay. But it made me wonder... "Why wisteria?" Not cherry blossoms, not chrysanthemums, but wisteria. Today, I want to dig into this mystery from the perspective of folklore and the traditions of "protection from evil." What is "Protect

Hey everyone, it’s Osamu! Demon Slayer  is just incredible, isn’t it? The battles, the characters... but what I find really fascinating is the deep mythology woven into the story. Today, I want to talk about the main antagonists: the Twelve Kizuki (十二鬼月) . We all know they’re the strongest demons directly under Muzan, but have you ever stopped to think about their names ? Why are they split into "Upper Rank" (上弦, Jōgen )  and "Lower Rank" (下弦, Kagen ) ? This isn’t random. It

Hello! This is Osamu, the manga blogger. In "Demon Slayer: Kimetsu no Yaiba," the only weapon capable of annihilating demons is the "Nichirin Sword." That sword wielded by the Demon Slayer Corps members—do you all just think of it as "a katana made of special metal"? The more I read the story, the more convinced I become that it's no mere weapon. I believe it's a type of "Magic Item" (Madougu) , crafted to sever the "curse" that is the demon by activating the "magic" that is

Hi, this is Osamu. The leader of the Demon Slayer Corps, "Oyakata-sama," Kagaya Ubuyashiki. He commands the absolute trust of the Corps members, but his existence is shrouded in mystery. What is particularly intriguing is the "curse" that plagues his family and the "true nature" of the role his clan fulfills. The Ubuyashiki family suffers under a terrifying curse—short lifespans—all because they produced the "stain of their clan," Muzan Kibutsuji. To break this curse, they ha

Hello! This is Osamu, your manga blogger. When you think of the appeal of Demon Slayer: Kimetsu no Yaiba , you probably think of the intense battles, fascinating characters, and the moving theme of family love... But one of the reasons I'm endlessly drawn to this story is its setting . That's right, the Taisho Era . Why was the Taisho era, a brief and tumultuous period of only 15 years, chosen? Not the Heian, Sengoku, or Edo periods? It's the period between the "civilization

Hello! I'm Osamu, the manga blogger. Man, lately I've been completely hooked on Demon Slayer  (Kimetsu no Yaiba) and Jujutsu Kaisen —two of Japan's proud, top-tier "curse and supernatural" battle manga. It's fascinating how these two series seem similar, yet their portrayal of "techniques" (Jutsu) is completely different, isn't it? While Jujutsu Kaisen  features highly "systematized"  battles with Domain Expansions and Cursed Technique Reversals, the "Blood Demon Arts" (Kekki

Everyone is the strongest, and everyone is noble. That is the fundamental premise. But, I’m going to do it anyway! I, Osamu, want to try and rank their "strength," mixing in my own "subjective judgment" and "deep analysis." This ranking isn't just about simple combat power; it also includes their mentality, the depth of their "karma" (or burden), and even their "mythological significance." Of course, I welcome any disagreements! With that said, let's get started! Hello! This

Hello! This is Osamu, your manga blogger. What makes the story of Demon Slayer  so captivating? In my opinion, it's not just the coolness of the Demon Slayer Corps, but also the incredibly tragic backstories of their enemies, the 'Demons,' from their time as humans. They aren't just 'evil.' They are also victims who, after facing inescapable injustice, societal abuse, and irremovable 'karma' (Gō), fell into the existence (or 'curse') of becoming a Demon. Today, I want to focu

Hello! This is Osamu, the manga blogger. When you talk about one of the charms of Demon Slayer , you have to mention the wide variety of "Blood Demon Arts" (Kekkijutsu)  that the demons unleash! I believe these aren't just simple supernatural battles. They are the very definition of "jujutsu" (sorcery/curses) —a distorted manifestation of the demon's own "karma" (go)  or their "lingering attachments from life." Of course, some are physically "strong" techniques, like Akaza's

Hello! This is Osamu, the manga blogger. Demon Slayer  has countless "great battles (best bouts)." But what truly draws me to this story is the "drama" behind those battles. It's not just an exchange of techniques, but a clash where "convictions," "attachments," and "curses" collide and send sparks flying. Today, I'm revealing Osamu's list of "soul-shaking" best bouts that you can't talk about without tearing up! [Demon Slayer] Can't Watch This Without Crying! Osamu's Top 7 "

Hello! I'm Osamu, a manga blogger. The Demon Slayer Corps members of "Demon Slayer: Kimetsu no Yaiba" use the technique known as "Total Concentration Breathing" to fight against demons beyond human comprehension. By improving cardiopulmonary function and controlling blood flow throughout the body, one gains the power to approach demons while remaining human. There are five basic styles of breathing (Water, Fire, Wind, Rock, and Thunder), from which a variety of other breathin

Hello! I'm Osamu, a manga blogger. The Twelve Kizuki are Muzan Kibutsuji's strongest pawns. They were a symbol of "despair" standing in the way of the Demon Slayer Corps. However, if we look closely at their "strength" and "Blood Demon Arts," we can see that they are not just fighting abilities, but that they have a conceptual "status" that is similar to the "gods" and "demons" listed in the "Dictionary of Oriental Divine Names." Today, we're ranking them as "demons"! Startin

Hello! I'm Osamu, a manga blogger. The Nichirin sword is the symbol of the soul of a Demon Slayer Corps member. It is the only weapon capable of destroying demons, and at the same time, it is truly a "living weapon" in that not only its color but also its "shape" changes depending on the "breath" and "soul" of the wielder. I'm convinced that this is now in the realm of a "Magical Tool Dictionary." It is the same as the "chosen weapons" such as the Kusanagi Sword and Excalibur

Hello! I'm Osamu, a manga blogger. Why do we cry when we read "Demon Slayer: Kimetsu no Yaiba"? This is because the words that the characters weave as if "spitting blood" at the brink of despair contain tremendous power. Since ancient times, Japan has had a belief in "Kotodama," the idea that words have spiritual power and can influence the real world. This is a powerful type of "sorcery," similar to the "spell" described in the Magical Encyclopedia, which binds phenomena wit

Hello! I'm Osamu, a manga blogger. The story of "Demon Slayer: Kimetsu no Yaiba" is truly a mixture of "despair" and "hope." The Demon Slayer Corps members throw themselves into "missions" with no guarantee of returning alive, and we readers have been pushed to the brink of "despair" along with them many times. Today, out of the many missions (story "parts"), I would like to announce **Osamu's ranking of the toughest missions (parts)**. It's not just that the enemy was strong
