Soul is the childhood friend of Chocolat and the twin brother of Woo. He is also a wizard.
Just like his brother, Soul has a deep liking towards Chocolat, often arguing about who gets to be Chocolat's king once she gets the crown. Later (but early) in the manga, him and Woo visit the Human world and enroll in Chocolat and Vanilla's school, as knights for the girls to make sure they stay safe.
In chapter 10, after being put in prison, he tells Chocolat there is an ecure shortage. Chocolat was shocked at this because she never expected that to happen, and because the Magical World's energy source is ecure. He then asks her if she picked up any hearts, to which her answer was no.
Soul, just like his twin brother, has a brash personality which can land him into trouble.
He is a dark-skinned boy with dark blue eyes and pointed witch ears and wears earrings. On his head, he has a hat-like scarf and wears a green scarf over his neck, with a baggy shirt and pants, along with pointed elf shoes.
Flight: Just like most witches, he has the ability to fly.
Flute: He is also able to play the flute, and carries it with him wherever he goes. In Rune 14, it is revealed that his flute is so powerful, it can even make a dragon fall asleep.
- Woo: The twin brother of Woo. Just like normal brothers, they often argue a lot. They both have the same crush.
