Veronica Liones was a decent minor character but definitely the most forgettable princess from the Kingdom of Liones.
She somehow didn’t get kidnapped by Hendrickson but ended up being tricked into thinking The Seven Deadly Sins were bad and Elizabeth was brainwashed. She definitely wasn’t the smartest.
Which causes her to fight with Elizabeth. But she ends up saving her life, apparently dying in the process. Yet returns for reasons poorly explained.
The only importance she has later is her romance with Griamore. Which turns awkward when he magically returns to a young age. Though it was cute how she acted like a mother during that time. After he’s restored, they presumably have a happy life together.
