How Old Is Yoriichi

One of the earliest to become known was Yoriichi Tsugikuni, in the "Demon Slayer: Kimetsu no Yaiba" series. The Between the fourteen swordsmen and his own ability, even among them he was unmatched I think he therefore stands out as a character. It is great difficulty to reproduce his Sun Breathing Technique. He is in charge of the technique's original form. It is this form that later serves as a model for all other breathing techniques used by Demon Slayers. A historical figure, Yoriichi Tsugikuni, hundreds of years before the main timeline of the story, seems to have fundamentally changed it.

Although the series never clearly tells us that Yoriichi Tsugikuni and Tanjiro are of a direct relation, there are numerous clues indicating they may be related by blood.At the point in time that the series takes place, Yoriichi is a major historical figure who lived centuries before Tanjiro lived. The Sun Breathing technique, which Tanjiro uses for his fighting style was developed by him, originally from China' Ma Long.'In addition to this, Yoriichi's earrings look extremely similar to Tanjiro's. It also suggests a family tie between them.

Old loyal to "Demon": one fact, Yoriichi Tsugikuni. Tsugikuni Yoriichi, one of the series's most path-forging figures. After achieving such a grand battle record, it was a great pity that his life could not end in some pinnacle showdown. However, he chose to mix together two known woods and in consequence form a new slipper, evidenced by the shoes he liked to wear- which were of oak and persimmon bark. He is as indulgent as he was tough for such a pitch to carry out. Mow him regularly has become second nature to the scion of a good family but that is not all this household habit entails. His wisdom was deep, and his life was long. The end of it brought a great heartache to those who had known him. All of a sudden they would grow up, then pass away: this is really hard for people to imagine.

Yoriichi Tsugikuni from 'Demon Slayer' is not a character whose height is clearly mentioned in the series, either in the anime or the manga. But judging by his appearance beside other characters, it's safe bet to say that he's got a fairly average height.

Bingo learned a lot from Demon Slayer! Yeah,Yoriichi Tsugikuni and Tanjiro Kamado are in fact connected. Tanjiro is considered a distant ancestor of Yoriichi. Amazingly both of these exceptional male figures have a unique birthmark which looks like a 'flame' as it runs across their foreheads; the sign has come from generation to generation. It denotes the creator's place as original practitioner of 'Sun Breathing' (Yoriichi). TAnjiro gets mark, breath style and begins his line up the ladder from there.,

Of course! Or in person of ninja Slayer Tanjiro Kamado seemed to have somethi ng to do with Yoriichi Tsugikuni. No, they weren't brothers, but they were united by blood, a connection that stretched down from ages past. Turned out that the legendary user of the sun-style breath was a distant ancestor of Tanjiro's. And here's the kicker-Tanjiro's signature Hanafuda earrings are not only a keepsake from his own ancestor but also Yoriichi 's parting gift to him! This bloodline business shifts the whole plot into high gear, and hands Tanjiro a real chance to root out the demons.

Yoriichi from 'Demon Slayer' transported into the 'One Piece' universe would be an absolute game-changer. His combat skills are on a level rarely seen even among the strongest in 'One Piece'. Yoriichi's mastery of the Sun Breathing technique allows him to move at speeds that could rival Kizaru's light-based abilities, and his precision with a sword would make Mihawk raise an eyebrow. The dude sliced through Muzan, a regenerating demon lord, like butter—imagine what he could do to a Logia user who relies on elemental dispersion. His ability to see the Transparent World gives him near precognitive combat awareness, letting him dodge or counter attacks before they even happen. In terms of raw power, Yoriichi doesn't rely on Devil Fruits or Haki, but his sheer skill and physical prowess would place him comfortably among the top tiers. His Sun Breathing techniques generate enough heat to incinerate demons, which could translate to countering abilities like Akainu's magma or Ace's fire. Yoriichi's presence would disrupt the balance of power in 'One Piece', as his style of swordsmanship and speed would force admirals and emperors to rethink their strategies. He might not have Conqueror's Haki, but his aura of sheer dominance would make even the likes of Kaido think twice before engaging.

The showdown between Yoriichi and Kaido in 'One Piece' transmigration is one of those epic clashes that makes you drop your snacks mid-bite. Yoriichi, this legendary swordsman with a tragic past, gets thrown into the chaos of the New World, and guess who decides to test his limits? Kaido, the so-called 'Strongest Creature.' The fight isn’t just steel meeting scales—it’s a collision of ideologies. Yoriichi’s calm, almost poetic swordsmanship contrasts wildly with Kaido’s brute-force dragon form. Every slash Yoriichi lands feels like a stanza from a death poem, while Kaido’s thunderous blows shake entire islands. The way their powers play off each other is insane. Yoriichi’s Sun Breathing techniques leave afterimages of flame in the air, and Kaido’s hybrid form lets him tank hits that would vaporize normal pirates. What really gets me is the emotional weight. Yoriichi’s fighting to protect a world he barely understands, and Kaido? He’s just bored out of his mind, craving someone who can finally give him a challenge. The fight’s got layers, like an onion made of adrenaline. Now, here’s the kicker: Yoriichi’s Transparent World ability lets him see Kaido’s muscle movements before they happen, dodging like he’s dancing on wind. But Kaido’s Conqueror’s Haki-infused attacks? Those are harder to predict. There’s this one moment where Yoriichi slices through a Boro Breath like it’s paper, only for Kaido to counter with a club swing that flattens a mountain. The aftermath is brutal. Yoriichi’s sword cracks under the strain, and Kaido walks away with a scar he won’t forget—both physically and mentally. The fandom still debates who ‘won,’ but honestly? The real victory is getting to witness two monsters redefine what a fight can be. Bonus detail: Kaido later mentions Yoriichi in a drunken rant, calling him 'that damn ghost who cuts too fast.' Pure gold.
