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

Hey hey, Osamu Manga here! This time, I'm taking a hard look back at "The Top-Selling Manga and Anime of the Last Decade," crunching the hard numbers, and dissecting why  they became such monster hits, Osamu-style! 1️⃣ The Manga That Took the Annual Top Spot (2015-2024) Champion Estimated Annual Sales Osamu's Quick Note 2015-18 ONE PIECE Repeatedly hit 11-14 million copies annually. 2019-20 Demon Slayer 12.06M → 82.34M  (← Insane numbers!) 2021 Jujutsu Kaisen 30.91M  copies 2

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

Hello! I'm Osamu, a manga blogger. Japan's two greatest curse battle manga, "Demon Slayer: Kimetsu no Yaiba" and "Jujutsu Kaisen." The "Blood Demon Arts" used by the "demons" in "Demon Slayer" and the "Magical Formulas" used by the "sorcerers" in "Jujutsu." These two "powers" may seem similar, but are completely different. What if the demons from "Demon Slayer" were reincarnated into the world of "Jujutsu Kaisen" with their "Blood Demon Arts" as their "innate techniques"? Who

Hello! I'm Osamu, a manga blogger. Last time, I dug deep into the origins of the Jujutsu Kaisen techniques and characters using an encyclopedia I had on hand. The more I learn, the deeper it gets! Well, we've received a lot of feedback from our readers saying, "I want to know more!" Thank you! So this time, we'd like to explore the very core of "Jujutsu Kaisen," " cursed energy " itself, while unpacking the materials. What is "cursed energy" in "Jujutsu Kaisen"? As is well k

Hello! I'm Osamu, a manga blogger. Today we will be discussing the deep swamp of Jujutsu Kaisen, getting to the heart of it all! As the title suggests, this setting has become common knowledge among fans: **"Gojo Satoru is a descendant of Sugawara no Michizane!"** Do you know how "bad" this is? It's not just that he comes from a noble family. It's a spine-chilling story that tells the story of how the roots of the most powerful sorcerer lie in the strongest curse in Japanese

Hello! I'm Osamu, a manga blogger. "Jujutsu Kaisen" is really interesting! Not only are the characters fascinating and the battles spectacular, but the underlying theme of a " curse " gives the story a sense of horror and depth. In the story, "curses" are depicted as "cursed spirits" that are the tangible manifestation of negative human emotions (fear, jealousy, hatred, etc.). Suddenly, I had a thought. "Does the curse in Jujutsu Kaisen have an origin? Maybe it actually

Hello! I'm Osamu, a manga blogger. So far we have dug deep into the origins of the characters and techniques of "Jujutsu Kaisen," but today we would like to take a step further and consider the " cursed energy " itself, which is the core of the work! Fantasy works feature powers such as "mana" and Chinese works feature powers such as "ki," but how is the "cursed power" in "Jujutsu Kaisen" similar to these, and how is it different? With my favorite book, "Magic Dictionary"
