===Souyaku Toaru Majutsu no Index===
====Operation Handcuffs Arc====
On December 25th, as Operation Handcuffs was spiralling out of control, a scared Vivana, carrying some of her torture-related possessions, was cornered in an alleyway by a pair of Anti-Skill officers, but a misunderstanding when she grabbed back one of her books coupled with the existent circumstances surrounding Handcuffs caused one of the officers to deem her harmful and move to shoot her. A disagreement and struggle with his fellow officer ensued, resulting in an accidental weapon discharge that killed them both, allowing a dismayed and embarrassed Vivana to escape with her life. Chapter 2 Part 1
Late that night, she attempted to obtain a fake ID from the counterfeiter Perfect Film in School District 6 (like many others targeted in Handcuffs), only to find him already dead. Running into Hamazura Shiage and Takitsubo Rikou at the counterfeiter's tent, Vivana noticed Takitsubo's condition and applied a moxibustion treatment to relieve it. Chapter 3 Part 2 In return for that (and making use of her Coin of Nicholas), Hamazura took her along as the two fled the scene. Chapter 3 Part 5 While the group were blending in at the park and trying to figure out their next course of action, when Hamazura learned he needed a special screwdriver to open up the hard drive he had obtained from Perfect Film's safe, Vivana suggested visiting the Urban Mine, the temporary trash storage area between School District 11 and 23.
Vivana ended up separated from Hamazura and Takitsubo on the underground way to School District 23, Chapter 3 Part 13 and while paused in a moment of indecision, encountered Risako, who was being pursued by a maddened Rakuoka Houfu. Vivana chose to protect the young girl from the murderous Anti-Skill Aggressor and managed to bring him down, but sustained life-threatening injuries in the process. Chapter 3 Part 16 Arriving at her destination later and finding Hamazura and Takitsubo under attack from the android Ladybird, she intervened despite her condition, sealing her fate. Before dying from her injuries, she told Hamazura how he could use her book and possessions to perform moxibustion for Takitsubo. Chapter 3 Part 18

In her clash with the muscular Rakuoka Houfu, Vivana made use of a bamboo sword with the tip broken into multiple pieces, turning a normal safe practice tool into something capable of tearing through flesh, using it to inflict pain to a weak spot as well as knock down a scattershot of rubble. She also used a yarai and rope in order to distribute the weight of her enemy's attack, both to stop it and break the pipe he was using as a weapon. Although her defenses were able to stop the attacks from killing her immediately, she still sustained life-threatening internal injuries. She also used burning incense and the produced smoke in her attempt to stop Ladybird, attempting to shove it in the android's mouth before being blown back.
