So here are the characters and their role in this T r a g e d y.
Italy Veneziano/Feliciano Vargas:
The main character of this story. Bubbly, kind, and a bit cowardly, Feliciano is a young man of twenty who moves to Japan with his brother to start a new life. However, he was attacked by a ghoul the night he moved there, and things have taken a turn for the worse for him.
Italy Romano/Lovino Vargas:
Main character. The grumpy older brother, Lovino has no trouble using profanity in every sentence he speaks. He has a tough exterior and often degrades his brother, but really cares for him a lot. Has a strange affinity for tomatoes.
Supporting character. A beautiful young woman that catches the eye of men and women alike. She is actually a dangerous rinkaku ghoul, and attempted to eat Feliciano, but was killed when hit by a truck. Since she had left the boy near death, they transferred her organs into his body to save him.
Main character. He's Second-Class Ghoul Investigator who often looks angry or serious, but really that's just how his face appears. He is a hard worker and focuses on the task before anything else. Ludwig is actually good at baking cakes, and has a strong love for his brother and dogs.
Supporting character. Gilbert is a First-Class Ghoul Investigator at the young age of twenty-six. He's actually egotistical and calls himself "awesome" almost 24/7. However, he has a great strength when it comes to fighting ghouls.
America/Alfred F. Jones:
Main character. Extremely energetic and surprisingly strong, Alfred is the youngest Ghoul Investigator at the age of nineteen. His terrifying willpower to exterminate all ghouls started when a ghoul handicapped his brother Matthew when they were little.
Supporting character. A cynical bikaku ghoul that raised Alfred and Matthew. Deeply cares for the two, but was rejected by Alfred when he found out Arthur was a ghoul.
Supporting character. A koukaku ghoul that is obsessed with eating Feliciano. Kind of a pervert and is constantly eating fancy dishes.
Main character. A quiet young man that works at Anteiku. He is an ukaku ghoul that was raised by the Ghoul Investigator Yao Wang. When Yao found out he was a ghoul, Kiku feared he would kill him- although Yao said otherwise- and slashed him on the back to stop him from doing so. He's had mixed feelings about his caretaker since.
Main Character. A First-Class Ghoul Investigator who raised Kiku, not knowing he was actually a ghoul at first. However when he eventually found out, he still cared for Kiku and didn't want to kill him. Unfortunately, the ghoul didn't believe him and slashed Yao's back in an attempt to escape.
Supporting character. Ivan is a rinkaku ghoul, just like Feliciano. He assists Feliciano later in the story as his bodyguard of sorts. Acts in a childlike manner and loves sunflowers and vodka. Also plans on bashing people's skulls in, too.
Supporting character. The quiet and calm brother of Alfred. He was attacked by a ghoul when he was young, and it left him paralyzed in his legs. He keeps a stuffed polar bear that Alfred bought him years ago.
So here's some basic info about the characters in this AU! I'm not sure who's all going to be in it though...
