Well, you could have 'The Bond between Demons and Humans' as a title. It gives the idea that there is some sort of connection between the two species in the story. Another option is 'Demons in the Human Realm' which focuses on the demons' presence in the world of humans. And 'Humans and Demons: Clash or Coexist?' also works as it poses an interesting question about the relationship between them.
Some possible title names could be 'The Encounter of Demons and Humans', 'Demon - Human: A Tale of Two Worlds', 'When Demons Meet Humans'.
Creative titles could be 'Demon - Human: The Forbidden Liaison', 'The Enigma of Demon - Human Relations', 'Demons and Humans: A Cosmic Conundrum'.
In a detective story, 'Sherlock' is an obvious but great choice for a detective character. For his sidekick, 'Watson' would be fitting. If you want a female detective, 'Scarlett' could work. It gives a sense of confidence and determination. And for a villain in the story, 'Malachi' has a bit of a dark and menacing sound.
'A Journey of Self - Discovery' would work well. In this type of story, the main character embarks on a journey, either physical or metaphorical. Along the way, they learn about their own strengths, weaknesses, dreams, and values. This title is suitable for a story that aims to inspire readers to also take the time to understand themselves better.
One could be 'Elixir of Lumina'. It's a magical drug in the fantasy story that gives the user the ability to see in the dark and also detect hidden magic auras. Another could be 'Mystic Mandrake Potion'. It has the power to heal any non - fatal wound instantly but is very rare and difficult to make as it requires the mandrake root which is guarded by magical beasts. And 'Dreamdust' is also a good one. When inhaled, it allows the character to enter the dream realm and communicate with spirits or gain hidden knowledge from their subconscious.
'Love Beyond Time'. It gives the idea of a love that is so strong it can transcend different eras. Maybe the lovers are from different historical periods but still find a way to be together.
'Sunrise of Love'. The sunrise is often associated with new beginnings and hope. In the context of a love story, it could mean that the love between the two characters is like a new dawn, bringing warmth and light into their lives.
Aria. It has a melodious sound and can be associated with a powerful sorceress or a mysterious elven maiden. Another one is Orion. It gives the feeling of a strong, heroic character, perhaps a brave warrior or a star - gazing wizard. And then there's Lyra, which could be the name of a gentle healer or a magical creature.
Well, you could consider names like Scarlett. It has a strong and feisty feel to it, just like Scarlett O'Hara in 'Gone with the Wind'. Or how about Harry? It's a simple yet very recognizable name, as seen in the 'Harry Potter' series. Also, Atticus is a great choice. It gives an impression of wisdom and moral strength, like Atticus Finch in 'To Kill a Mockingbird'.
Marlowe. Philip Marlowe is a well - known fictional detective. It has a noir - ish feel to it, and it's a great name for a detective who is a bit of a loner and is tough but also has a moral code.
Well, there are quite a few. 'Data' from 'Star Trek' could be a name. It has a modern and technological feel to it. Then there's 'River' from 'Firefly'. It's a name that has a sense of mystery and fluidity, like a river. Also, 'Arya' from 'Game of Thrones' (which has some science - fiction elements in its world - building) is a strong name, signifying a fighter.
