Blade

Blade is a member (and wanted criminal) from a group called the Stellaron Hunters- Founded and led by a certain being named Elio, also known as Destiny’s Slave, they are a mysterious organization that collect Stellarons.

Blade, previously named Yingxing, is a swordsman who abandoned his body to become a blade. He pledges loyalty to Destiny's Slave and possesses a terrifying self-healing ability. In the past, he used to be a blacksmith with extreme talent, but because of a certain event, he died and became immortal from the Mara. When he is in a state consumed by Mara called Mara-struck, he becomes ‘something else’, according to his words. To stop that from happening, Kafka, one of the other members of the Stellaron Hunters, uses her ability, Spirit Whisper to suppress his Mara.

Mara, also called the "Long-Life Curse," refers to the negative effects that afflict long-life species at a certain point in their life cycle involving cell transformation that result in bodily growths and loss of sanity. Those afflicted by Mara turns into monsters, a shell of what they used to be before. The cause of mara is not entirely understood, but different sources point toward either immortality obtained through Yaoshi the Abundance, or the accumulation of memories and the inability to process them over a long period of time. According to Blade, everyone experiences mara in different ways; however, his situation is unusual. Although mara haunts him, memories of it seldom cross his mind, be they of remorse, hatred, fear, or reflection. He describes himself as becoming something else when his mara strikes. Blade had been suffering from memory loss even before the Stellaron Hunters found him.

Stellarons are mysterious objects that spread across the universe like a cancerous growth, and they are considered seeds of disaster which cause massive changes to civilizations and ecosystems.

Elio is an unknown being who has the being to foresee the future possibilities, and in the shape of a “script”, Elio guides his hunters in their missions.

Kafka is a member of the Stellaron Hunters who is calm, collected, and beautiful. Her record on the wanted list of the Interastral Peace Corporation (IPC) only lists her name and her hobby. People have always imagined her to be elegant, respectable, and in pursuit of things of beauty even in combat. She has a special ability called Spirit Whisper, which allows her to hypnotically manipulate others through language. Through this, she manages to suppress Blade’s Mara.

The Nameless is a group consisting of all people who travel the stars in the name of Akivili and the path of the Trailblaze. They ride a large train called the Astral Express to travel through the galaxies, created by an Aeon/god, Akivili the Trailblaze, though after Akivili’s disappearance, it fell into disrepair and eventually crash-landed onto an unnamed planet. Himeko discovered the wreckage and repaired the Express, becoming its navigator and forming a new group of Nameless. The Astral Express Crew's goal is to retrace Akivili's steps, repairing the star rail they laid down thousands of years ago and sealing the Stellarons threatening the galaxy. The leader of the Nameless is Himeko, and the other members are Stelle, Dan Heng, March 7th and Welt.

Himeko is an adventurous scientist who encountered and repaired a stranded train as a child, she now ventures across the universe with the Astral Express as its navigator.

Welt, real name Joachim Nokianvirtanen, is an animator by trade, he is a seasoned member of the Astral Express Crew and the former sovereign of Anti-Entropy who has saved Earth from annihilation time and time again. He inherited the name of the world, "Welt."

Dan Heng is the cold and reserved train guard and archivist of the Astral Express. Wielding a spear named Cloud-Piercer, he joined the Express crew to escape his secluded past.

March 7th is an enthusiastic girl who was saved from eternal ice by the Astral Express Crew, and has the unique ability of being able to use "Six-Phased Ice."
