HP: My Brother, the Savior!

Also known as My Daily Life as Everyone's Darling at Hogwarts, originally titled My Brother! The Savior.

Completed

[Harry's Younger Sister + Slytherin + Black Hair, Green Eyes, and Looks Like Lily + Wish-Fulfillment Power Fantasy + Academically Gifted with Exceptional Magical Talent + Everyone's Darling + Female Lead in a Female-Oriented Story + Harry's Generation]

The heroine has overpowered advantages: an incredible ability to learn, exceptional magical talent, and vast reserves of magic.

The main story is all romantic tension, with everyone a potential love interest. The extras feature separate romantic routes-I'll write whichever ones you want to see.

After transmigrating into HP, she was still a little dazed. But after thinking it over carefully-hey, she was the Savior's little sister! As a character who never existed in the original books yet was closely tied to the protagonist, either she would be sacrificed so her brother could gain boundless power, or she would follow the protagonist and crush everyone in their path.

But she wasn't very familiar with the original plot, so her only option was to study hard and try to keep pace with her brother as he swept aside all opposition.

Yet ever since she started school, Mia had watched Professor Snape spew venom at Harry while treating her pleasantly? At the very least, anyone with eyes could see his favoritism.

Mia: "Maybe I just have a likable face?" (Scratches her head in confusion.)

Canon pairings will be broken up, possibly including Ron/Hermione, because I ship Krum and Hermione.
