This is my first anime character duel card! I decided to choose two strong swordswomen: Kagura from Fairy Tail and Akame from Akame ga Kill!
Who would win?
Akame of the Demon Sword Murasame
Arguably the deadliest assassin of Night Raid, Akame is powerful enough to wield the infamous imperial arms Murasame, nicknamed the "One-Cut Killer" because it kills people with just one cut by injecting them with lethal posion. She can run at Mach (velocity of sound, approximately 340 meter per second), attack with deadly accuracy, and is skilled in hand-to-hand combat.
The strongest wizard of Mermaid Heel, Kagura wields the sword Archenemy and has Gravity Change magic so powerful it can overcome the Gravity magic of the celestial spirit Libra. Kagura can defeat opponents without even unsheathing her sword. She cuts down the 13th celestial spirit, Ophiuchus, without even drawing her sword, in mere seconds. A skilled swordswoman, she is a match for Erza, shattering her Adamantine armor with one slash. Kagura is also is very fast, shown crossing several meters in an instant, and able to keep up with Erza in her flight armor.
