Sirius

Biodata

Background / History

Sirius grew up under Walburga Black’s increasingly restrictive rules and expectations concerning bloodlines, Dark Magic, and family honor. Although he recognized that his mother loved him, he experienced that love as suffocating. His attempts to obtain comfort gradually gave way to deliberate rebellion, including rejecting her insistence that he enter Slytherin 14.

He was fond of his younger brother, Regulus, but their differing attitudes toward the Black family made family matters difficult to discuss. Regulus remembered a brother who once enjoyed playing with him, in contrast to the gloomy, mocking Sirius he later knew at home 14 49.

Merlin’s Previous Lives

• In earlier loops, Merlin and Sirius were usually casual acquaintances who sometimes exchanged conversation or revision notebooks. When Merlin belonged to Slytherin, their relationship was openly antagonistic 2 12.
• In one remembered life, both were imprisoned and tortured in Azkaban. Sirius approached Merlin as a black dog, placed her hand on his head, and repeatedly assured her that she would escape 5.
• Merlin remembers witnessing his death and reflects on the twelve years he endured in Azkaban. These memories concern an earlier course of events, not his present status as a Hogwarts student 48.

Appearance

• Gray eyes, repeatedly emphasized during his confrontations with Merlin 1 5.
• A fringe that can obscure his expression when he lowers his head 5.
• Strikingly handsome: he received romantic attention even before Hogwarts, and Merlin calls him the school’s best-looking boy 14 22.
• Careful about his presentation: Merlin recalls him straightening his robes before mounting a broom 23.
• Future height: Merlin remembers that he becomes very tall, with a growth spurt beginning in his third year 20.

Personality

Sirius is proud, sharp-tongued, and intensely sensitive to comparisons with his family. Compliments once pleased him, but he grew contemptuous of praise that seemed directed at the Black name rather than at him. His rebellion is also contradictory: the route guidance explains that he opposes what his family approves of rather than inherently rejecting Dark Magic or dark wizards 5 14.

His demeanor changes markedly with his company. Merlin remembers him as cold and arrogant when alone but animated and smiling with James and their friends. His loyalty has an exclusionary side: he treats Remus’s concern for Merlin as a possible betrayal and frequently demands that James choose sides 5 6 17 35.

His hostility can become violent. When Merlin exposes his insecurities about belonging to the Black family, he strangles her despite Madam Pomfrey’s intervention. Nevertheless, his concern for Merlin also breaks through his antagonism: he rescues her at the Astronomy Tower, notices her fear of heights, and later refrains from revealing it to their friends 5 22 32.

Abilities & Skills

Spellcasting and Transfiguration

Sirius successfully transforms a match into a needle during his first Transfiguration lesson 4.

• Exchanges spells with Merlin during their ongoing feud 13.
• These exchanges repeatedly result in lost house points and detention; the narration specifically distinguishes them from using curses 13.

Potion-Making

Sirius claims that he could make Wit-Sharpening Potion after watching it being brewed once 10.

• The claim occurs while he is mocking Merlin’s exhaustion.
• The provided scene does not show him brewing the potion himself 10.

Physical Combat

Sirius is physically stronger than Merlin during their early fights, though she has substantially more street-fighting experience 9 11.

• Uses his strength to shove and restrain her 5 9.
• Is not invulnerable to retaliation: Merlin injures his arm during the Hospital Wing assault, and their later fight leaves him bruised 5 11.

Animagus Transformation

In Merlin’s memories of another life, Sirius transforms into a black dog while imprisoned in Azkaban 5.

• Uses this form to approach and comfort her.
• His acquisition of the ability is not documented in the current school storyline 5.

Observation

Sirius notices details that others overlook or have not yet connected 22 41.

• Deduces Merlin’s fear of heights from her avoidance of flying and Quidditch practice 22.
• Notices that Remus touches something on the Whomping Willow’s trunk before the tree becomes still 41.

Relationships

• Merlin Mei — His romantic interest and frequent opponent. Her resemblance to the Black family conflicts with his immediate attraction to her, producing denial, jealousy, insults, and repeated confrontations. Merlin does not understand the feelings behind his falling affection score 1 5 14.
• James Potter — His best friend and closest companion. Sirius resents Merlin’s growing closeness to James, while James repeatedly tries to reconcile them. At the end of their first year, James invites Sirius to spend the holiday at his home 3 9 19 44.
• Remus Lupin — Friend and fellow Marauder. Sirius becomes jealous when Remus shows concern for Merlin, but joins the effort to investigate his recurring full-moon absences 17 31 41.
• Regulus Black — Younger brother. Sirius cares for him, but their opposing responses to family expectations create distance. Their reunion after Regulus’s Sorting ends before Regulus can ask why Sirius chose Gryffindor 14 49.
• Walburga Black — Mother. Her controlling upbringing drives much of his rebellion; she sends him Howlers after his Gryffindor Sorting 4 12 14.
• Narcissa Black — Cousin who condemns his associations and treats his Gryffindor membership as a disgrace to the family 13 49.
• Lily Evans — Fellow Gryffindor who attacks him after learning that he strangled Merlin 6.
• Severus Snape — An antagonistic schoolmate whom Sirius calls “Snivellus.” Sirius mocks his clothing and flying mishap, and reacts angrily when Merlin intervenes on Snape’s behalf 5 23 40.

Story Role / Major Arcs

Romance System

Attraction and Affection

Sirius’s “Love at first sight” monologue reveals that he first noticed Merlin’s loneliness at Platform Nine and Three-Quarters and followed her onto the train. Seeing her face directly intensified his attraction, but her resemblance to the Black family made that attraction unacceptable to him 14.

• Negative affection is not a straightforward measure of indifference. Route guidance explains that continued affection losses can reflect his inability to accept feelings and traits associated with his family 5.
• Jealousy persists despite apparent hostility. Once his “Love at first sight” achievement is unlocked, Merlin spending time with others can provoke jealousy even when their relationship looks very poor 13.
• Merlin’s interpretation is incomplete. She generally reads the deductions as evidence that he hates her, while his monologue explicitly confirms his attraction 14.
• The Mirror of Erised remains unresolved. Neither Merlin nor the group learns what Sirius saw; their guesses about inheriting the Black family are not confirmed 15.
