Majiri Agakura

Majiri Agakura is an Agakura family member of extraordinarily dangerous repute.

Appearance
Majiri is a young woman with straight black hair that nearly reaches her waist in the back and slightly exceeds shoulder length in the front; her hair is adorned with an ornament and her ears with two large hoop earrings. She wears a short sleeved sailor-themed uninform of dark hue, the left sleeve of which sports an armband displaying the title "Head of the Family" in kanji.

Her large, light-hued umbrella features a black splash-design over a grey circle; in the middle of the splash is the white outline of what may be an eye.

Personality
Although Momoya Agakura has remarked Majiri cannot ever focus on a single person for very long, she appears to be possessive of her family and extends that possessive streak toward those who catch her interest by inviting them to join the Agakura Family as adoptees; not only does she extend this invitation to Xiaoyu Lei when de-limbing him, she renews the offer upon their reunion nearly a decade later. She furthermore uses endearing language when addressing or referring to Xiaoyu and Momoya, such as "sweet little kidsassin-kun", "silly little brother," and calling them both 'cute' and 'adorable'; by constantly referring to her status as sister and Momoya as her brother, she invokes and reinforces their family bonds.

Her threats of punishing Momoya are similarly reinforcements of and reinforced by the family bonds she holds in such high esteem. Her disarming smiles, meanwhile, are threatening in and of themselves; they belie the confidence, authority, and dangerous skill she wields with pride.

Xiaoyu Lei Encounter
Almost a decade prior to the start of the series, Majiri, Kana, and Momoya Agakura together slaughter a small-time group of terrorists that have been causing trouble for more than one organization—including the Lei Family, a young assassin of which by the name of Xiaoyu Lei arrives at the same building with orders to slaughter everyone inside.

Majiri is impressed when Xiaoyu ruthlessly attempts to cut her throat and furthermore recognizes he must be a Heilei. So, she suggests Xiaoyu let the Agakuras adopt him; then, she severs his arms and legs in such a way as to prevent fatal blood loss. Speculating that the Heilei might make him into a t'ing fu as a consequence, she gathers up Xiaoyu's limbs and says she will return them on the day Xiaoyu decides to accept the adoption offer. Before the siblings take their leave, Majiri introduces herself to Xiaoyu with her full name.

Ten Years Later
About two days after the Shinoyama estate arson incident, around the time Tsubaki Iwanome and Kōzaburō Arase are leaving a curry restaurant, someone on Shinjuku's streets mentions having heard that Majiri will be arriving in Tokyo soon. The speaker's identity is unknown, as is the specific context for Majiri's travels.

Roughly a week later, give or take a day—finds Majiri and her sisters Dahlia and Kana committing the murders of at least two people in a sheltered parking lot. Majiri's attempts to reach Momoya's cell phone fall, much to her ire, and she decides they must fetch him—somehow sensing or otherwise knowing Momoya is currently in Shinjuku on its east side. The sisters track Momoya down to some manner of warehouse, outside of which a crowd of Fire-Breathing Bugs are singing Furusato. The Bugs disband at Majiri's demand, and the Agakura sisters enter the building unchallenged.

Inside the warehouse are four people: Takumi Kuruya, mildly injured; Misaki Sakimiya; Momoya, passed out from terrible injuries, and, unexpectedly, Xiaoyu Lei. Xiaoyu detects the sisters' arrival; by way of greeting, Majiri severs the forearm of Xiaoyu's prosthetic right arm. She reminds him of her promise to return his limbs should he become an Agakura, but Xiaoyu rejects both the Heilei and the Agakuras in favor of his new allegiance to the Shinoyamas—and with that, attempts to deliver a devastating kick with his right leg.

She catches his knee and 'busts' it, more than irked that the Shinoyamas ruined her chance to recruit him; when Momoya weakly laughs at her plight, she threatens to punish him but meanwhile compliments Xiaoyu for having grown as an assassin. Momoya corrects her: the one who inflicted his injuries was the girl overhead.

Misaki swings her prybar at Majiri, who catches it with her teeth and swipes her hand at Misaki's torso; however she is taken aback when Misaki separates her upper and lower halves in a flock of bats. Recovering swiftly, she tosses the prybar over to Misaki and demands her name, whereupon she invites Misaki to take on the Agakura name as well.

When Momoya coughs up blood, Majiri realizes her brother will die without medical treatment and calls upon her sisters to act: Kana retrieves Momoya while Dahlia ensures Misaki will not interfere. Deeming the encounter a draw, Majiri apologizes for breaking Xiaoyu's prosthetic (though reminds him she will return his real one if he joins them) and tells Misaki she will be seeing her again. The sisters thus leave with Momoya in their care.
