"Mamma mia! I can't believe you convinced me to put on this outfit..."
"What? It's all part of your official merch."
"Yeah, but I'm not sure about how this 'sexy Ferrari driver' look suits me."
"Don't be such a downer! You look great for this year's Halloween! Come on, let's have some fun with some bounty hunting this night..."

Although they were separated shortly after birth, Gosia and Imola remained in contact with each other. Even though they were (nearly) identical twins, they still have some very noticeable differences in their characters. Gosia remained with her mother in Poland, who proudly stands for her Dullahan heritage, and Gosia is not to shy about it either. Imola, on the other hand, moved with her father to Italy. Her father wanted to keep their heritage hidden, and hoped that they'd integrate more into normal society. But with Imola's racing success, that plan went out of the window in a whole different way. Nonetheless, Imola remains more reserved than her sister, and only a select few people outside the Dullahan community know that she's a Dullahan. Compared to her, Gosia seems to be a bit more unhinged...

You also see this reflected in their weapon of choice. Each Dullahan, by tradition, receives their own blade, a symbol to willingly serve the ancient spirit Lucifer, the one who punishes evil souls (but contrary to popular belief, he's a good guy. It's just his duty to do the "dirty work"). Gosia has picked a hook sword, a popular and versatile weapon among the more adventurous Dullahans, like the bounty hunter she is. Imola, however, has opted for a more elegant Italian rapier, a more precise weapon. Dullahan swords are enchanted, and not only do they have the capability to cut off parts of others without actually injuring them (both parts will still be alive), they can also "create" more Dullahans with them by transferring their curse. Furthermore, the sword itself has a mind of its own, and they also help Dullahans to deal with their curse. If however, a Dullahan goes off the rails too far, their sword might refuse to co-operate and even swear allegiance to someone else, possibly one of their victims.
