My OC child for Hunter x Willow: Lillian "Lily" Park.
Since Hunter and Willow learned not to keep their feelings bottled up, they raised Lily to be honest about her feelings. She's straightforward enough to the point of being too blunt sometimes. It makes her come off as unapproachable, which makes it hard for her to make a lot of friends.
Her palisman is an elephant, symbolizing strength, for Lily's strong body (from workouts with her parents) and strong mind (the wisdom of an elephant). Her named "Ella" because she's just that straight and to the point.
Her courses are Plant magic like her mom, Potion magic like her dad and an Illusion magic sash for her Uncle Gus.
