Harry Potter Fan Fiction:Hermione meets the heterochromatic girl: magic rules break.

Overview

This fanfic begins with Hermione Granger meeting Anna Grindlevault, a mysterious girl who lives behind a disguised magical barrier in a hidden London house. Hermione—ostracized and lonely at school—keeps running into Anna, and Anna repeatedly “fixes” the world around her with unusual, high-level magic: rain barriers, cleansing spells, and a secret ability that lets her cast magic through a wand and beyond.

Their bond forms fast, but it’s complicated by Anna’s backstory—she is not fully human.

Key Plot Highlights & Standout Moments

First meeting + “no magic exists” twist

• Hermione meets Anna while Anna is reading something like a dark magic compendium.
• Hermione is confused because she’s been taught magic can’t exist, establishing a core theme: what Hermione believes vs. what’s real.

Anna’s concern becomes real emotion

• When Hermione’s school pain cracks her open (crying over bullying and rejection), Anna responds with genuine empathy.
• This matters because Anna had previously shown “not experienced emotion.”

Hogwarts arrival + Minerva reveals magic

• Hermione’s parents initially resist magic.
• Anna proves it by performing a transformation (coffee table → small sheep).
• Professor McGonagall then supports Hermione and helps introduce Anna as her friend.

Diagon Alley + wand reaction

• Hermione receives a rare wand chosen for her.
• A standout moment: the wand seems to “leap” in her hand, reacting to Hermione’s magic.

Sorting + Anna blocks the hat’s singing

• The Sorting Ceremony includes comedy: Anna finds the Sorting Hat annoying.
• Anna casts a spell to block her ears, and Hermione is sorted into Gryffindor.

Troll rescue with “purple lightning”

• Chaos escalates when a troll enters the school.
• Anna saves Hermione using her signature spell: purple lightning—awesome and lethal to monsters/dark entities.
• McGonagall awards major points, cementing Anna as a legendary-level threat (in a good way).

Room of Requirement + dungeon-level puzzle

• As Harry deals with “term problems” and the Chamber plot escalates, the story becomes action-adventure focused.
• Anna and Hermione collaborate through high-stakes magic, including chess-like trials and clever trap bypasses.

Voldemort’s return threat + identity mechanics

• A disguised Quirrel/Voldemort situation evolves into a direct showdown with Anna.
• Anna defeats Voldemort’s vessel using her unique magic (“purple lightning”).
• Voldemort retreats, revealing he’s still fractured and tied to soul-splitting.

Anna’s origin: alchemy made her; the Philosopher’s Stone made her “real”

Later reveals explain Anna’s existence:

• She is an alchemical homunculus, created from an “obscurus” merging with a construct.
• She originally lacked a soul, and had to be “given” heart/emotion through the Philosopher’s Stone, with further help through later inheritance/legacies.

Chamber of Secrets climax

• Hermione’s necklace + dagger repeatedly save her.
• The Chamber plot becomes personal: Anna fights the basilisk/diary-driven soul absorber.
• Professors intervene as needed, while Slytherin’s lingering presence grants Anna knowledge/power.

Romance Arc

From friendship → intimacy → undeniable partnership

• The relationship begins with Anna emotionless and distant, treating people almost like experiments.
• Hermione is the first person who truly stays, even when most would reject Anna.
• Their bond becomes the “engine” of the plot:
  • Anna’s magic improves as her emotions become real.
  • Hermione’s confidence grows because Anna treats her as someone worth protecting.

By late story:

• Their relationship is no longer subtle.
• They act like committed partners—openly romantic in how they protect each other and how Anna’s future plans explicitly include Hermione.
• There are multiple intimate scenes (kissing/cuddling), including a strongly emotional moment where Hermione chooses Anna openly after being scared for Anna during danger.

Founders’ Secret Legacies & Trial Mechanics

Helga Hufflepuff’s and Rowena Ravenclaw’s hidden legacies become a major structure for the fic:

• Gryffindor: strength/courage trial.

• Ravenclaw: logic + temptation + trust test, including the most painful moment— Hermione must cast Crucio on Anna to pass (painfully established as “soul trial mechanics”).

• Hufflepuff: herbology/potions/creatures knowledge.

These trials deepen Anna’s abilities and reinforce the theme: love + sacrifice unlocks power.

---

Jokes, Tone, and Reactions

• Anna frequently rolls her eyes at Dumbledore, Lockhart, and the Sorting Hat—a recurring humor thread.
• She blocks unwanted noise and uses “nope” magic/attitude rather than traditional schooling vibes.
• Lockhart becomes a running gag: he publicly embarrasses himself, while Anna (and sometimes Carl) neutralize him when he crosses boundaries.
• Ron’s prejudice drives major emotional conflict:
  • He assumes Slytherins are evil.
  • He’s repeatedly proven wrong.
  • Eventually he’s forced to accept Anna as a real ally.

Character Notes (Personalities)

• Anna Grindlevault – cold exterior, sharp humor, gradually deeper emotion; protective, strategic, and sometimes terrifyingly powerful.
• Hermione Granger – loyal, brilliant, stubbornly moral; her bravery evolves from anxiety into decisive leadership.
• Dumbledore – warm but manipulative when needed; theatrics and sweets included.
• Harry Potter – repeatedly targeted; conflicted but becomes more pragmatic due to Anna/Hermione’s interventions.
• Ron Weasley – prejudice-driven early; gradually humbled; protective but struggles with trust.
• Minerva McGonagall – strict, competent, and surprisingly impressed/approving of Anna’s heroics.
• Professor Snape – antagonistic presence with occasional usefulness; on a protection trajectory underneath.
• Draco Malfoy – proud/hostile early, later supportive; shifts allegiance and apologizes when it matters.
• Voldemort/Quirrel – fragmented, paranoid, antagonistic; repeatedly escapes when defeated.
• Supporting cast: Moody, Lupin, Hagrid, Filch, Percy/Weasley family—mostly through events, rules, and rescues.
• Pansy Parkinson – recurring threat; later tied into Chamber conspiracy and assassination-style plots.
• Founders’ ghosts (Salazar, Rowena, Helga, etc.) – test virtues (courage, calm reason, sacrifice, loyalty) and grant legacies.
