REVAMP (B/c why not)

What up nerds, here's a fellow nerd for you.

Name: Roshan Azar
Age: 16
Birthday: November 23
Year: 6
House: Slytherin
Wand: Vine, Unicorn core, 10 inches, Hard
Favorite Subject(s): Charms, Potions, Dueling
Disliked Subject(s): Divination, Arithmancy
Appearance: Black hair (with dyed streaks), green eyes, a smug look
Noticeably short at 4' 8".
Notes: Wants to be the very best, the best there ever was. Extremely earnest & not very good at picking up on social cues. Workaholic who might literally die if they take a break. Their intensity and stubbornness can make them seem unapproachable. They're lonely but don't realize it. Also a prefect as of their 5th year.
Half-blood (but it's complicated: Dad was a squib. Mom and younger brother (Navid) don't have magic.)

Name: Zadkiel Hanan Eun-Yeong
Age: 12
Birthday: February 4
Year: 2
House: Hufflepuff
Wand: Laurel, Phoenix core, 13 inches, Slightly Yielding
Favorite Subjects: Neutral on beginner subjects (but would like divination)
Disliked Subjects: Neutral on beginner subjects (but would admit under pressure that the premise of Muggle Studies was kind of... not good)
Appearance: Dark brown hair, brown eyes. Pretty tall for his age at 5' 4".
Notes: He's good-natured to the point that you can probably kill him, and he'd forgive you! The mom friend (tm). Wants to do good in the world. Sweet but not really all that bright. No one alive knows what his anger looks like.
Technically a pureblood, but was raised by muggles.

Name: Kathryn "Cady" Jurnee Hernandez
Age: 16
Birthday: August 7
Year: 6
House: Slytherin (Transfer student from Eaglecrest where they were Primary house Shrugstagram & secondary house Laxdisick. They arrived 3 days after school started, when the Sorting Hat was put away. They just sat down at the Slytherin table because snakes sleep 20 hours a day which is #relatable)
Wand: Beech, Dragon heartstring, 11 3/4 in, brittle
Favorite Subjects: Transfiguration, Charms, History of Magic (though it's way better when taught by a Justitopian)
Disliked Subjects: Potions, Flying / athletics
Appearance: 5' 6", freckles, wears an Eaglecrest baseball cap instead of a witch hat
Notes: Somewhat annoyed by the restrictions on outside technology in Hogwarts but isn't Justitopia enough to protest about it, so she's just growing weed and key lime underneath the bed (also how she plans to make friends & money at Hogwarts). Likes to have a good time, chill, and avoids confrontations. Would sell you out for a bag of Hot Fries.
Pronouns: She/her
Sexuality:
