ABOUT
"Alchemized Voice" is a virtual singer project centering on Alchemist ZETHIEL, who alters his voice to sing in different ways via "alchemization."
1. VIRTUAL LIVE SINGER
At the final stage of the self-alchemization, ZETHIEL realized his true awakening. Wanting to convey his heart to the world, the full emotion and nuance of his voice can be heard, as he continues to grow and blossom.
2. VIRTUAL SYNTHESIZED SINGER
Vocal fragments across multidimensional space-time carry the memories of ZETHIEL's journey. He gathers these vocal fragments to construct synthesized vocals that he can use to expand the range of his singing potential and possibility -- and to tell the story of his fragmented past.The singing synthesis based on ZETHIEL's expressive, highly skilled, yet progressively changing vocals creates a range of musical possibility. It is his desire that he can share his emotive voice with you, as a means by which you may freely express your musical creativity and ideas.

RECORD 1
In the sky, there is a realm between worlds. Between my dying breath and my renewal, I look towards the bright sun, in hopes it will guide me back home. But I know that my journey is not over. In fact, I will be reborn into another world once more, drifting further and further away from home.
RECORD 2
There are many beautiful things in this world. The clear blue sky, the dazzling of the stars, the vastness of the seascape… and you. I don't want to let go of what makes this world beautiful. I don't want the light to die out.
RECORD 3
I don't want to be alone. My heart lingers in a distant memory, ebbing back and forth between the past and present. If you could be by my side, and quell the instability in my heart, I will hold on to you.
RECORD 4
It's a bit embarrassing, it's a bit frustrating. It's the picture of desire as I melt into your arms. This is the end, but it's just the beginning. I'll sustain myself off of your soul for the rest of my life, until my final breath.
RECORD 5
In heaven, there is no solace. There is only an echo of love that remains. It was cut up into pieces, bloodstained by this cruel world. Even still, into the next life, I have to take up my sword. I devote my everything to you.
RECORD 6
Everything is collapsing. It's a repeat of "that day." It's a repetition of destruction I've seen in countless worldlines, starting from the very first world. If there's even a chance those worlds can still survive, I'll fight and cut the threads of fate myself.
RECORD 7
My ideals, my emotions, my everything. I want to stay true to myself, but my heart will be broken no matter what I do. Even still, I travel endlessly throughout these worlds to search for the truth of what happened "that day," and why we exist in these worlds together.
RECORD 8
When one life ends, another one begins. I'll lose you once more as I am reborn into another life. But no matter what, my memory will persevere. I will take hold of these memories, scattered throughout the worlds, and cherish them forever. I will not let memory fade.
RECORD 9
I am alone. In this world, my heart searches endlessly for something, only to feel empty. You are not here. I can only hope you lie within distant starlight, as I gaze towards the starry night sky. You are a memory glowing against a backdrop of endless darkness and despair.
RECORD 10
For all our sins, and for all our happiness – do we seek redemption? Everything hurts under the weight of these lives tenfold, and more. The blades against each others' skin, the heartbreaks, the deaths – I wonder what it all meant to you. Amidst a bittersweet longing, I can only wait to see you again.
STORY OF ALCHEMIZATION
Total Origin
On the same Earth we live on, there was a child named ???.
The child had an exceptional skill for singing, but something was missing from ??? life.
By some twist of fate, ??? was transported to another world, never to be seen again.
Still, ??? hopes to return home someday.████ Haven
The young child was summoned to the world of ████ Haven, a world on the brink of apocalypse. For his exceptional singing ability, he was recognized by the goddess ████, and was to become one of the ████ to save the world. He learned that in this world, singing is a magical power that he has the aptitude to wield.He chose the name "Zethiel" to live this new life.The ████ were trained by ████ herself to refine their magical skills to fight back against the ████. All of the ████ showed bright potential and strength.Over the months, the ████ became close, and it was time to unleash their song – the song that would save the world. However, all would fall apart when Zethiel's voice collapsed. He couldn't sing anymore, he became weak and overcome by his despair. As the ████ fed on negative emotions, he inadvertently accelerated the apocalypse, and ████ Haven was destroyed.But in that moment before destruction, ████ put her all into saving the ████ and sending them off to different worlds before they could get killed. She perished alongside ████ Haven.Zethiel's Necklace
A blue diamond-shaped necklace. It's a memento from his time in ████ Haven, when he became a ████. It was given to him by ████. When he sings, the necklace glows.████ Island
Zethiel ended up on a floating island called ████, a "space between worlds" and an place of rest. None of the other ████ followed him, so it seems they were all dispersed across the multiverse in different directions. While other visitors to ████ could come and go from their original worlds, Zethiel could no longer return to his homeworld, nor to ████, so he made ████ his new home.He realized one of his key weaknesses was his ████ – the reason he succumbed to despair, was because his singing voice did not convey his true heart or identity. Thus, he wanted to find a way to change his own body.While meeting the otherworld visitors every so often, he took an interest in alchemy to become stronger. Over the next four years, he began to study alchemy from different worlds and people, for the final purpose of altering his body and enhancing his own singing magic.The Final Stage of Self-Alchemization
At age 18, after 4 years, Zethiel completed the final stage of self-alchemization. Upon realizing this, he could convey his "truest song" at long last, and created a transmission to his home world.He was finally strong enough. His mission was to find a way to ████ once more, and save it properly this time. Though it was collapsed, the necklace he has is proof that ████ still "exists" in some capacity. After that, it would be to find a way back to his home world. He hoped the transmissions would help guide his way back home.So he left ████, and set sail across the multiverse.Zethiel's Essentials
Testosterone Potion: An oral potion taken monthly to steadily and consistently masculinize the body. (Different from the kind found in our world.)Song Magia Potion: A standard potion to increase Magic potency, altered for the purpose of singing magic.Body-Changing Alchemization: An advanced spell that took four years for Zethiel to complete. It altered his body to his own liking, and also enhanced his agility, magic adaptability, and otherworld adaptability. This means he can easily travel between different worlds without beingDimensional Watch: A custom-made device. List of features:
- Multiversal Map: Fills out more as he travels across worlds.
- Property Analysis: Analyzes the makeup and properties of entities. Useful in gathering materials for alchemy.
- Teleportation: Limited within the bounds of a specific world for a certain distance.
- Transmission: Send a transmission across worlds.Atelier Dimension: A pocket dimension Zethiel created that's tied to himself. No longer belonging to a world, he created his own. This is where he rests, works, and other such things. It also acts as a "ship" that can sail across the multiverse.
