The characters from both could work together to solve cases that involve both the normal and the supernatural.
Arcueid Brunestud, with her vampire - like powers and her own complex backstory, could also be a great character to include in a crossover. Her powers could interact in interesting ways with characters from other franchises, and her story could add more depth to a crossover fanfiction.
In my opinion, Shiki Ryougi is really fascinating. Her past and her special ability to see death lines make her a unique character. She has a complex personality that is shaped by her traumatic experiences. Then there's Fujino Asagami. Her power and her struggle with her own nature are quite captivating. Also, Tomoe Enjou is an interesting character as he is involved in some of the most mysterious parts of the story.
The 'garden of sinners visual novel' has a complex plot. It involves a world filled with mystery and supernatural elements.

One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.

A Thundercats and Star Wars crossover fanfiction would be really cool. The Thundercats could be in the Star Wars universe, and their unique powers and weapons could be a great addition. Maybe the Thundercats could help the Jedi or the Rebels in their fight against the Sith or the Empire.
