There are many weapons to choose from in anime, with everything from shuriken to scythes to baseball bats appearing across different series. However, one of the most popular, and often lethal weapons used is a sword. While the type of sword differs between characters, the deadliness of the weapon do not.

Swordsmen have a strong reputation in anime as being fast, powerful, and deadly, and this reputation is not unearned.

However, when push comes to shove, they exhibit their true power. For this reason, while fans may appreciate meeting the character in real life, they would never want to truly fight them.

However, the worst part about fighting Akame is her sword, Murasame, which will curse anyone she cuts with it, spreading throughout their body and killing them nearly instantly.

He annihilated Zeke in their match, and in his fight with Kenny, Levi used not only his swords but also his gear and anything else he could get his hands on to kill his attackers.

4 Reinhard Would Only Need To Swing His Sword Once

Reinhard van Astrea is the most powerful swordsman in the Re:Zero universe. Luckily he is a good person, but he would spell trouble for everyone if he were a villain. While the anime has not shown too many of Reinhard's fights so far, the one viewers saw between him and Elsa was so impressive it proved Reinhard's capability.

However, it was the fight between Reinhard and Puck that truly cemented his worth, as he destroyed the rampaging spirit with a single swing of his sword. With that much power, it would be truly foolish to challenge Reinhard to a fight.

3 Teresa Would End The Fight With A Smile
