The battle between the bows and strings echoes. What kind of unique music will he play this time?
Humans and demons compete, no matter who is the best
Faced with the challenge of playing a G string solo, the Violinist shocked the world with his incredible techniques, but all this was at the cost of becoming a puppet. If he relied solely on talent and hard work, could he recreate that peak performance?
Through the Violinist's Once costume - Demon's Symphony, we see the state of his first deal with the devil - in the empty and dim concert hall, the violinist is still practicing for the upcoming grand performance, with a red devil mask covering the upper half of his face, and the bow was firmly in the Violinist's hand. He gained the upper hand in this battle between man and the devil. He declared his unyieldingness with an exaggerated smile, and even mocked the devil's attempts at control with disdain!

Dancing with the devil, the sound of the piano echoes
Of course, how could the devil's control be broken so easily? When the ribbon controls the bow and strings, magical sounds begin to reverberate in the concert hall.
Violinist - Demon's Symphony is dressed in a solemn performance suit, and the close-fitting tailoring highlights his slender hands, making people intuitively feel his talent; his thin legs support the body in a twisted posture, seeming to be fighting fiercely against the devil; red ribbons fly, tightly entwining the bow and strings, displaying inhuman skills as if the devil came to the world; under the red devil mask, the eyes emit golden light, obviously the Violinist Antonio is still fighting the devil to the death, and his smile has not changed at all, making people believe that he will never lose easily, and that is exactly the case! Perhaps this is just a bold attempt to dance with the devil. After completely regaining control, the Violinist - Demon's Symphony will use human hands to stir the melody of the world.

Mainly anti-customer, crowded Manor
In the character showroom interface, we can see more clearly the true situation of the Violinist - Demon's Symphony: After several slightly painful struggles, he started to play calmly and confidently, and the red ribbon took advantage of him and snatched the violin away. He continued to play at a dazzling rhythm, but the Violinist - Demon's Symphony, paid no attention to it. Instead, he waved his hands lightly to beat the music, as if he was directing the melody of Demonic Sound. The devil never really took control of the violin, and the Violinist showed a higher level of playing.
During the chase, the Violinist - Demon's Symphony walked leisurely, pulling the strings from time to time to play music, and the red musical notes kept flying, giving the survivors unforgettable music and taking them to enjoy the carnival of the chase. Lifting the bow with both hands, who is the real owner of the magic sound?

Design Idea Plans
Violinist Antonio’s retracement will go back to the time when he first met the devil and made a deal with him.
We wanted to distinguish the appearance design of "Once" costume from Antonio's state of being controlled by the devil. Therefore, we replaced his iconic long hair when possessed by demon with the ribbons of the mask.
Background Story
The Violinist Antonio was imprisoned by the princess and forced to compose music scores. When his inspiration ran out, the devil emerges from a mask of court drama and tempts Antonio to make a deal with him—to sell his soul and body using his musical talent as bait. However, Antonio relied on his persistence and pride in music to gain the upper hand in the confrontation, and instead controlled the devil in the mask for his own use.
This time, he lifted the bow with both hands and became the real master of the magic sound.
Design Idea Sketches
The Once series mainly shows the moments of struggle when the characters are not completely plunged into darkness. The first sketch already showed certain contradictory characteristics, but it did not fully meet expectations. The image design does not fully conform to the background of the times in some aspects, such as the design of the heels, sleeve patterns, bows, and the burning feeling on the edge of the ribbon is not smooth. At the same time, the special effects on the screen are slightly insufficient and can not better show the character's inner conflict at this time.

On the basis of the above, we optimized the design and overall improved the texture of the characters and pictures. Remove some modern features from the clothing to restore the characteristics of the times. The ribbons and patterns have also been optimized, and special effects designs on masks, violins and musical notes have also been added to make the picture more impactful.

In the end, we further modified and upgraded some details to make the visual presentation smoother and more in line with the background story of the character.
Model Details Description

Showroom Interface Design

After a struggle, the ribbon extended from his mask, and the Violinist finally took control of the demon's power for his own use.

The sound of the piano is long and lingering, and he is still the talented Violinist.

However, when the Violinist relaxes, the power of the devil is waiting for an opportunity to push his consciousness into the corner of his mind. The silk ribbon is wrapped around the bow, playing an unknown magical music score.
In-Game Display

The eyes of the Violinist's mask and the edges of the ribbon shone with strange firelight. He walked forward slowly, gazing intensely at everything in the Manor. Who is dancing under the magic sound?
