Thorn along with the Six Kings of Pure Color attained level nine and decided to create a treaty that separates their territories and disallowed fighting amongst each other to obtain level ten. She was with the other monarchs during a meeting where she watched Red Rider get killed by Black Lotus.

Plot Outline[]

Crimson Storm Princess Arc[]

Purple Thorn only makes an appearance in a flashback that Yellow Radio had previously recorded to incapacitate Black Lotus when he showed it to her. It is revealed during the this flashback that the Monarchs of Pure Color were having a meeting. Red Rider was expressing his opinion against fighting amongst each other and stated that he had respect with one another. Black Lotus replied that she too had respect for him and decided to hug him as a sign of respect. However, the Purple King, Purple Thorn stated that was too much as a sign of jealousy. However, Red Rider responded by stating that it's Black Lotus' way of shaking hands since she doesn't have any. Black Lotus took advantage of his kindness and used her ability, Death By Embracing to kill him. Purple Thorn started screaming in horror and she and the other Monarchs attacked Black Lotus. Once the thirty minutes were up, Black Lotus linked out and went into hiding.


Purple Thorn[]

Purple Thorn is a pure purple Duel Avatar. She has a regal figure, which, along with her ownership of the Tempest, earned her the title of Empress Voltage.

Enhanced Armaments[]

  • The Tempest – The second of the Seven Arcs, represented by Beta Ursae Majoris, also known as Merak. It takes the form of a staff that can shoot white lightning without using its user's SP gauge.[1]


  • Elementary Charge – A Special Move that allows Purple Thorn to charge another Duel Avatar's SP gauge with her own. The amount charged will be increased by 1.60217662 times the amount spent by Thorn.[1]
  • Frontal Thunder – Wields her staff that emits before discharging a purple thunder strong enough to electrocute her targets.
  • Judgement Blow – An ability given to all Legion Masters that allows them to instantly uninstall Brain Burst from one of their legion members. Purple Thorn can uninstall Brain Burst from anyone in Aurora Oval.


  • Thorn Retribution – An incarnate skill that allows Purple Thorn to fire white lightning several orders of magnitude more powerful than the Tempest's default ability.[1]


  • She likes recruiting electric users into her legion, and accidentally recruited Crimson Kingbolt due to thinking "Kingbolt" meant a very powerful electric attack.
  • The ability Elementary Charge is a reference to the elementary charge, the smallest magnitude of isolated electric charge possible, whose value in SI units is 1.602176634×10–19 coulombs, but in natural units is 0.30282212088.
  • It is implied during the flashback, that Purple Thorn was romantically involved with the Red King, Red Rider. The game Accel World vs Sword Art Online: Millennium Twilight seems to reference this even further, as Purple Thorn called Red Rider “the love of her life”.
