Hishiri is an officer of the Department of Policies within the Clock Tower, which typically serves to regulate and, if necessary, punish mages in violation of Clock Tower rules, such as potential exposure of mysticism. It is believed that she and Doctor Heartless are adopted siblings, but unbeknown to even herself, they are secretly half-sibling by a different mother.
In reality, much of her life was shaped by her desire for revenge against her father. Heading into the depths of the Spiritual Tomb of Albion on his own, he abandoned his ex-wife and son entirely out of nowhere upon his return. Giving birth to her through his second wife, he died a coward. In order to prove the worthlessness of her father, she joined the family of Norwich before slipping into the Department of Policies, the easiest route for a magus with no pressure from their own bloodline.
As a result, she coincidentally received information from the Department of Policies' Information Division, and became strangely obsessed with a certain Doctor Heartless. She began pursuing him, thinking there was a possibility he was her long lost brother, Adashino Kurou.
For the last ten years Adashino has secretly run a yearly poll among the female students at the Clock Tower asking which men, both students and professors, they most want to sleep with. This poll is the Department of Policies' covert way of learning what magi have the most influence in the Clock Tower.
Both Gray and Waver describes her as similar to a snake, elegant and ever calculating. As with most magi, Hishiri is efficient and remorseless, taking no issue at luring a large group of potential troublemakers to a deathtrap under false pretenses.
She has expressed disinterest in the Root, believing the idea of ever reaching it to be a pipe dream and only wishes to continue performing her duties.
She acts as El-Melloi II’s first rival. If Heartless is his Moriarty, then she is his Irene Adler. Though the chance of developing a romantic relationship with someone was never there for El-Melloi II.

Lord El-Melloi II Case Files
case. Adra Castle Separation
Hishiri was the officer assigned to manage the inheritance affairs of the Adra Castle case, although her true role wouldn't be discovered by Waver until later.
On the next day, Hishiri briefed the guests on Geryon Ashborn's will and the challenge they would need to overcome in order to claim Adra Castle and its secrets, which was to guess the name of a certain angel. This was all however, a ruse set up by the Policies Department and the deceased Ashborn. During the night, Hishiri removed herself from the equation by falsifying her own murder with a prepared corpse and remained hidden to observe the other guests.
Reappearing unharmed at the resolution of the case, Waver voiced his suspicion she and her department had intimate understanding of the history of Adra Castle and most likely sent troublesome individuals there to eliminate them. Hishiri does not deny Waver's accusations and instead tells him to consider his own role in the grand scheme.
Adashino was one of the participant involved in the incident concerning the Marburry Workshop created by Trevor Pelham Codrington. She arrests and binds Wills Pelham Codrington when he arrives at the estate with Lord El-Melloi II, Reines El-Melloi Archisorte, and Gray in tow, stating that he is most likely the one who caused the leyline disruption and the death of his father, backed by Waletta Codrington's claims that only a necromancer like Wills could have erased Trevor's traces within his remains to stop her from interrogating him. Lord El-Melloi II manages to get her to release Wills as this is circumstantial evidence and a vicious storm outside prevents anyone from leaving, allowing him to investigate in the meantime.
When Waletta dies later, Hishiri is further convinced Wills is the suspect, but Waver reminds her that his investigation is not yet complete. In the aftermath of the case, Hishiri reveals Wills was not born with his Fairy Eyes, but they were in fact obtained by Trevor through the Rail Zeppelin. Policies' true motive was to obtain Trevor's records of the Rail Zeppelin, which she provides a copy of to Waver.

case. Grand Roll
Hishiri invites Lord El-Melloi II and Gray to a tea ceremony on the roof of one of London's skyscrapers, meeting the two so they can discuss Doctor Heartless' plans. She tells them that, although Heartless used a Subcategory Holy Grail that he created himself to summon and maintain Faker, it will inevitably be influenced by the original, meaning that once the Fuyuki Holy Grail War ends, Faker will disappear. She theorizes that all of this means he will have to take action soon, to which El-Melloi II responds that his plan is likely underway. Hishiri then gives the Lord an enveloppe informing him that a Grand Roll will take place in a few days.
Acting under orders from Reines El-Melloi Archisorte, Adashino and Goredolf Musik place Lord El-Melloi II under house arrest in his office. She creates a bounded field resembling a white snake across his doorway that forces him back when he tries to leave. They did this so that he wouldn't learn what his students were doing in Snowfield.
The glasses she wears are Mystic Eye Killers. Just as her brother Doctor Heartless (Kurou Adashino) once possessed, she has the Mystic Eyes of Finding, which having the ability to find lost things. In her investigations, the reason Hishiri was able to reach such precise results so quickly was because of those eyes. Of course within the Department of Policies they were of great use, but they were also used to help find her brother.
Her specialty is Poison and her Element Affinity is Water. Hishiri's magecraft revolves around bundles of white cloths that she is capable of instantanously animating into snake familiars, large enough to constrict a full-grown man from head to toe. She typically hides several bundles under her clothes and can spontanously eject them from her sleeves to either restrain someone or to seal off exits. Her familiar is capable of reconnaissance and can become completely invisible and undetectable, allowing it surprise its targets. When dismissed, the snake will dissipate into a black fog. She uses an Original magecraft based on the fusion of eastern and western divination. Hishiri also uses snake-style Bounded Fields.
She is quite cunning, as she understood that all it took to falsify her death was by preparing a similar looking corpse and then destroying its eyes to immediately convince people the corpse was her. This trait also makes her a master actor, allowing her to fool even someone like Dr. Heartless and lure him into a trap devised by her and Waver.
If El-Melloi II had “a first rate sense of being a magus but a second rate skill,” then Adashino was “a magus of first rate skill, but no sense of being one.” Though her nature is closer to that of a Spellcaster, her place in the Department of Policies which has given up pursuit of the Root fit her perfectly.

Adashino Hishiri [Person]
The snake of the Faculty of Law. Her elemental affinity is Water. Her specialty is Poison.
In this story, she was El-Melloi II’s first rival. If Heartless is his Moriarty, then she is his Irene Adler. Though the chance of developing a romantic relationship with someone was never there for El-Melloi II.

Of course within the Faculty of Law they were of great use, but they were also used to help find her brother.
As a bit of a digression, she has been entertaining herself greatly with the arrival of the new, plump, and somewhat out of place member of the Faculty of Law.

A pseudonym for the Faculty of Modern Magecraft.
Alternatively, the “Daddy Long Legs” family of the Clock Tower.
Having been fortunate with money for generations, the Norwich family has a tradition of adopting people of interest, causing the name to spread throughout the Clock Tower. Once upon a time, Adashino Hishiri and Heartless bore the name, but later cut their ties with them. Neither of which was a particular concern to Norwich, due to their strict philosophy of “It’s not worth pursuing those who flee.”
The name Norwich came to be associated with the Faculty of Modern Magecraft due to the strong backing the Norwich family provided when it was being set up as one of the twelve main Faculties of the Clock Tower.
While the current head of Norwich has taken an interest in El-Melloi II, due to their complex political situation, Reines has decided it is best for them to keep their distance. After all, she had long since given up hope for her brother to possess such a sense for politics.
