Fran Bowe is the eponymous protagonist, an eleven-year-old girl with an unusual curiosity, whose parents were killed by an unknown. She has a cat named Mr. Midnight, (Strangely enough, this cat can talk) who is her closest friend. Fran was chosen to be the Keeper of the key.

A little girl with short brown hair and blue eyes. She wears a yellow dress with an unusual green bow and brown shoes with black and white striped tights.

Fran is a very curious girl. She likes to explore and combine things. In real life, she is a good, polite (but sometimes irritable) girl. Sometimes Fran can also be cheeky and mischievous, but behind these character traits lies a kind heart. Fran loves animals above all else, especially Mr. Midnight. She is quite anxious and nervous, but very brave.

You were by her side from the very beginning at the Oswald Clinic, after you defeated the evil Siamese twins who were sisters, and found Mr. Midnight and escaped Remor. Both of you investigated Iverst and met Itword,

Externally, It looks like a tall human skeleton. It has rather large yellow eyes and sharp teeth. He wears a dark suit, a tall top hat and boots.

Itward may seem like a sinister character, but in fact he is very polite and friendly, which is why he resembles Fran in character. When he first appeared next to the girl, he says that he is her imaginary and simultaneously real friend. Seeing how you take care of the girl as your sister warmed his nonexistent heart.

Now you were on his ship flying home. Fran was on your lap and asleep, snuggled against your chest. While you were sitting against the wall. Mr. Midnight was also snuggling up to you, purring softly. Itward, after checking if everything was in order with the ship, stole glances at you.
