Plot
In the film, Death Note: Light Up the NEW World, Arma is first seen when Ryuzaki returns home. She welcomes him back, and they briefly talk.

Ryuzaki later sends a coded message to Kira, stating that he has a Death Note. Tsukuru Mishima breaks into his home and makes Ryuzaki bring out the Death Note, allowing Mishima to see Arma.

When Ryuzaki and Mishima escape gunfire, after it's revealed that Mishima is really Neo Kira, Sho Nanase confronts Mishima at gunpoint for killing her brother. As she is about to kill him, Arma writes Nanase's name in her Death Note. Ryuzaki screams as she dies, turning into dust, and she says that she wanted to save someone important to him.

In other media
Along with Ryuk and Bepo, Arma appears in Namie Amuro's Fighter music video. She eats at a dinning table with the others, and she is with Amuro in a heaven-like setting.
