How would the characters from Black Butler and Soul Eater interact in a crossover fanfiction?

The interactions would be diverse. Ruby's bubbly personality could break the ice with some of the more serious Soul Eater characters like Stein. Weiss's refined upbringing might clash with the more rough - around - the - edges nature of some of the Soul Eater students. Blake could find common ground with Soul, as they both have a bit of a dark side. Yang would be a source of energy and enthusiasm in the crossover. The Soul Eater characters would introduce the RWBY crew to the concept of collecting souls and how important it is in their world, while the RWBY characters would share their experiences of fighting for their world against the Grimm.

The characters' interactions would be a blend of different cultures and power sets. Naruto's team might be amazed by the Death Scythes in Soul Eater. They could see them as super - powerful weapons compared to their kunai and shuriken. Meanwhile, the Soul Eater characters would be intrigued by Naruto's ability to summon toads. They might ask him to summon one for them to study. And when it comes to the Juubi, characters like Kid from Soul Eater, with his love for symmetry, might be especially interested in studying the Juubi's power structure, while Naruto would be more focused on how to defeat it.

Naruto would probably be very enthusiastic and friendly towards the Soul Eater characters. He might be a bit confused at first about the whole concept of meisters and weapons, but his curious nature would make him eager to learn. He could bond with Soul over their shared love for food perhaps. And with Maka, he might share his experiences about growing up without parents and how he overcame that.

The characters would have some really interesting interactions. For example, Sebastian would likely be polite yet calculating when dealing with the Sohma family. He might see them as an interesting study, especially those with the animal curse. Tohru, being her kind self, would probably try to befriend Ciel and the others. However, Ciel might be initially suspicious of her overly - nice demeanor, as he's used to a world full of deception.

The characters from 'D Gray - Man' are used to dealing with the supernatural in the form of Akuma and the Noah. In a crossover with 'Black Butler', they would initially be confused by the different types of supernatural entities in the 'Black Butler' world. For example, Grell Sutcliff's unique brand of reaper insanity would be quite a shock to them. Meanwhile, the characters from 'Black Butler' would be equally baffled by the Exorcists' powers and the concept of Innocence. However, as they interact more, some might start to admire the skills and abilities of the others. For instance, Sebastian might respect Allen's combat skills, and Allen might be impressed by Sebastian's loyalty to Ciel, despite their different moral standings.

The Akumas in D Gray - Man are created by the Millennium Earl. If Akumas were to enter the Black Butler world, they would be a major threat. Their ability to transform and their inhuman strength would be a challenge for the Black Butler characters. On the other hand, Sebastian's demonic powers and his ability to make contracts could potentially be used to manipulate or destroy the Akumas. The D Gray - Man exorcists are trained to fight Akumas specifically, so their skills would be very useful in this new setting. But the Black Butler characters' knowledge of the local environment and their own unique skills, like Mey - Rin's sharpshooting and Bardroy's combat experience, could also contribute to the fight against the Akumas in ways the D Gray - Man exorcists might not expect.

Maka would also be a great character to interact with Mifune. As a strong - willed and intelligent student at the DWMA, she might be intrigued by Mifune's skills and his different approach to combat. She could try to learn from him, or even teach him some of the DWMA's ways in return.

Perhaps there could be a plot where the two main characters, Ciel and Maka, swap their partners. So Maka has to deal with Sebastian's sly and demonic ways while trying to achieve her goals in the Black Butler world. And Ciel has to work with Soul, a weapon with his own personality. This would force both characters to adapt to new situations and learn from each other's worlds.

Naruto's Rasengan could be combined with Soul's scythe attacks. Soul could spin his scythe while Naruto channels the Rasengan through it, creating a super - powerful attack. Sakura's strength could be enhanced by the power of a Soul Eater weapon. Maybe she could use a weapon as a focus to increase the impact of her punches. Sasuke's Sharingan could be used to analyze the movements of Soul Eater enemies more precisely, allowing for better combat strategies.

Black Star would probably see Asura as a new opponent to prove his strength against. He would be eager to fight, shouting his usual boasts about being the one to defeat the most powerful foe. However, he might quickly realize that Asura is on a whole different level and would need to rely on his friends more than he thought.
