Mamoru Hijikata might be the least known swordsman among the other monsters on this list, but when it comes to swordsmanship ability, he stands tall as one of the best characters to ever pick up a sword in the world of manga.

Mamoru was already a highly skilled swordsman before he lost his vision. Now that he has become blind, Mamoru uses high-tech glasses and a walking stick to help him see some sort of simplified version of three dimensional objects. But when it comes to facing the enemy, Mamoru relies more on his ability to detect the killing intent of his foes.

Not to mention, Mamoru also uses a sword with a blade that utilizes bleeding edge molecular technology that allows him to cut virtually every material on earth. All of those things combined enabled Mamoru to become a much more lethal swordsman than he ever was before.

The samurai in Hell's Paradise are not just regular samurai - they are executioners. Even more so than a common samurai, an executioner has to finish their job in one sure-kill slash because otherwise it would only add unnecessary pain to the subject. Which is why it is even more amazing for a blind man like Shion to not only be able to be an executioner, but also climb to the top as one of the best in the Yamada Asaemon clan.

The reason why Shion is capable of doing this impressive feat despite losing his vision is because he perceives the world in a different way. He has the ability to “see” life force energy, known as Tao, emitted by everything around him.

Shion has been able to see Tao since he was a child, so he is much more proficient in it than most people around his age. "Seeing" and "feeling" the Tao of his opponents allow him to use his sword in such an efficient manner with extreme accuracy. Not only that, but Shion can also use his own Tao to enhance his strength to the point that he becomes one of the strongest characters in the series.

“Hashira” is the title bestowed upon the strongest fighters in the Demon Slayer Corps. There's only a handful of people who manage to attain this level of power in every generation. Gyomei Himejima is the current leader of the Hashira and also the strongest one of them all.

Gyomei is a bit of an outlier, not only among other Hashira, but also among other characters on this list. The reason is because he doesn't actually use a sword. Gyomei's main weapon is something called Kusarigama, a small but thick ax connected by a chain to a spiked ball.

Kusarigama is a hard weapon to use for normal people, so the fact that the blind Gyomei can masterfully use it is a testament to how skilled and powerful he truly is. One of the main reasons why Gyomei can do unbelievable things despite having no vision is due to his super enhanced hearing ability. Add to that his ability to access the "Transparent World" later on in the series, and he’s virtually one of the most powerful human beings in the world.

If we're talking about blind swordsmen in shounen manga, then one of the most iconic characters is definitely the former captain of the 9th division of the Gotei 13, Kaname Tosen. He was blind from birth, but in exchange for the loss of his vision, he gained the ability to better sense the spiritual energy (Reiatsu) of everything around him. It's like the enhanced version of Shion's ability from Hell's Paradise.

Tosen's extreme Reiatsu sensing ability combined with masterful swordsmanship, strategic combat ability, and proficiency in Kido techniques makes him one of the top fighters even among other captains in Gotei 13. Tosen famously goes toe to toe with the monster that is Kenpachi Zaraki. And if you consider the bankai and numerous attack variations that Tosen has, he is definitely one of the strongest swordsmen on this list.

There are so many crazy strong characters within the world of One Piece. Some come from the side of the Pirates, while others come from the side of the lawful Marines. And when it comes to Marines, the ones that stand at the top of the food chain are the Admirals.

Each Admiral has the power to destroy a nation by themselves, so they’re literally monsters in human skin. But one of the most interesting admirals right now is a man named Fujitora. He is a blind middle-aged man who likes gambling. He is also a master swordsman who can control gravity.

Unlike other characters on this list, Fujitora's blindness is self-inflicted because he is tired of seeing all of the evil in this world. However, his powerful Haki enables him to perceive the world around him and it even enhances his reaction time. The full extent of Fujitora's power is still unknown at the moment, but he can easily create a meteor with his power and drop it onto the enemy. So it is safe to say that he is a one-man catastrophe.
