Sun Day

"... little Sun, who was shaping up to be a genius... and a bit of a smartass..."

- Wednes Day in Regret

Description
Sun Day is the youngest of the Days, who was born shortly before Apollo's death. Not much is known about her other than what Wednes Day says to Kiddy in Regret. Apparently, albeit being highly intelligent, she appears to be unable to accomplish the simple task that is baking a cake; whether this is due to her own capabilities or some sort of curse is unknown.
