Rida Arin

Rida Arin is the current Number 4 Reaper. She is extremely powerful and fast, and has earned the nickname "The Dancing Knight".

Personality
When she first appears to save Sorin, she comes across as confident and sweet. According to Cora, however, Rida can also be quite bratty and competitive, and constantly gets into fights with Ludwig Song.

Amelia Arc
While travelling through the East to get to her objective, Rida noticed the descended Amelia Savos attacking Sorin, Danya and Balota. She intervened, destroying Amelia and saving the others. Once Sorin had woken up and Balota and Danya resurrected, she left to complete her own mission.

Powers and Abilities
Rida possesses all the powers of a Reaper, including increased agility, speed, strength, and healing, as well as the ability to come back to life. Like all Reapers, she is able to enter the unseen world and slay the Descended and Twisted.

She wields a twinblade that can separate into dual swords. She holds one in reverse grip and the other properly, and is seen twirling around the battlefield, using her speed to spin her body around faster and add momentum to her swings.

Trivia

 * Rida is the fastest Reaper alive.


 * It was mentioned by Cora that Rida and Ludwig's powers are actually evenly matched. This is possibly part of the reason they have such a rivalry, and have even gone as far as to kill each other in the past.
 * Rida's fighting style is partially inspired by Captain Levi from Attack on Titan.
