Jackie Tristan

A stylish woman with short hair and tan skin, wearing cargo pants. She is thought to be a foreigner based on her name and appearance, but it remains a mystery.

She refers to herself as "I" and is generally called "Jackie," and by Kutsuzawa as "Ms. Jackie."

She has a calm demeanor and is caring, like a big sister.

She lived in a poor family with her father and younger brother. On her birthday, her father gave her boots that were stolen goods and too big, but she cherished and took care of them. At one point, her father and brother were murdered in what seemed to be retaliation by someone from whom her father had stolen, and her brother's blood stained her boots, which triggered the awakening of her Fullbring.

In the decisive battle with the Shinigami, she fought Renji but was unable to even draw her sword against the significantly more powerful Renji, who had powered up after the battle in Karakura Town, and was defeated. However, she was moved by Renji's actions trying to save her as Yukiyo tried to erase the space they were fighting in, intending to kill herself to save Renji, but survived by losing her Fullbring powers.

After the battle, she met with Yukiyo and said, "Yeah, I'll be waiting," in response to Yukiyo's promise.

In the final chapter, like Shishigawara, she did not appear much unlike other members.

In the novel version, she does not appear directly but works at Yukiyo's company.

In the anime version, she is shown living alone in an apartment. Also, her dislike for Fullbring is revealed earlier than in the original work.

Fullbring: "Dirty Boots"

Her Fullbring, which she activated when her cherished boots were stained with her dead brother's blood, is a symbol of her trauma, which she despises.

The dirtier the boots get with mud or blood, the more her attack power increases, doubling in strength as they get dirtier.

She emits a black liquid-like spiritual pressure from her armor, which dirties her entire body, enhancing her strength. After gaining Ichigo's power, she can emit this black liquid-like spiritual pressure from her armor to strengthen herself.

Upon activation, she transforms into a figure wearing a cap and jet-black boots that reach up to her thighs. Later, after gaining Ichigo's power, she is covered in white clothing with armor resembling a motorcycle muffler on her right shoulder.

In episode 352 of the anime "XCUTION Encyclopedia," Riruka suggested that she could start dirty from the beginning, but it was revealed that this would inconveniently destroy the ground just by walking due to the increased strength.
