Astrid and Astral are twins who do everything together. They hunt together, they laugh together, they sing together, and they live together. A childhood incident with their parents caused them to become their evil selves, hunting down innocent spirits with the belief that they would get love from that. The love they never had. They are part of a clan called the Lurker Clan, where they are known as Treble and Bass Clef because of their love of music. When Astrid gets shot with an arrow through her lung, the clan doesn't know how to function without their Treble Clef. She's not the only one who gets killed, though. One Lurker from each group (Claw and Fang, Piano and Forte, Audio and Vision etc.) gets killed, and they're forced to make peace with the Dweller Clan if they want to keep the Lurkers and Dwellers from going extinct. While all that happens, Astral gets severely ill. The Lurkers have no idea if he'll survive or not.

This is Number 96 speaking...or writing...whatever. Some of you may know me as Black Mist...or Dark Mist if you don't watch the Japanese version. If that's the case, I suggest you call me Black Mist from now on. This is about my experience with a creation I wanted to make. She was a failure. BUT not as much as I thought. You see, even though she was stupid and acted cute all the time, she was still smart enough to save my life...

Astral learns more and more about his past, and he eventually learns Black Mist's secret. Black Mist has been imprisoned for years, making his evil grow to where it is now. That power came with a price, though, and he never mentally matured. Black Mist vowed he would never forgive Astral, but will he break that vow?

Sequel to Test Subjects 1 and 2. Astral and Black Mist seem to be safe from the government. They have destroyed all of the files that the government had of them along with their father's, Dr. John Smith, journal. Or have they? The government agents have duplicates of the files of "Test Subjects 1 and 2," and they plan on getting rid of the illegal beings. Astral and Black Mist struggle to remain hidden when they find out that they're being sought out, even resorting to being tucked away into the Key John made for them. It won't be that easy, though.

Astral is put into a coma when something hits him on the head while fighting the Barians for the seemingly last time. Yuma and his friends die during that battle, and the Barians die many years later. Astral wakes up in Dr. Eggman's lab. Sonic, Shadow, and Silver break him out of the lab and warn him of Dr. Eggman. All the while, Silver and Astral become close like he and Yuma were. History will most likely repeat itself, for Eggman brought the Barians back to life, too. Astral and his new friends will also have to rely on an old enemy.

In the year 5067, Doctor John Smith is a scientist who loves making artificial life forms. He's married, but his wife cannot carry children, so he promised her that he'd make her a very special child. That's how Astral, also known as "Test Subject 1," and his twin Black Mist, also known as "Test Subject 2," were made. Their existance is illegal, though, and when the government finds out about them, they want them obliterated. Will they die, or will they live on?

CHIBI STORY! Astral and Yuma roam the woods for fun in the morning. They get separated at night, and Astral encounters the infamous Slender man. While trying to get back, Astral meets up with Felix, also known as PewDiePie, the guy Yuma always watched on YouTube. Together, they muscle through the ordeal and find the exit. But to what cost? (Takes place somewhere like Slender the Arrival)

Black Mist has escaped, and his thirst for blood is greater. Astral's inner Darkness has emerged, and Black Mist will take advantage of that. Black Mist has a secret, though. One that explains why he's out to kill Astral. Will the eight Agents plus Yuma and Cathy defeat Black Mist, or will Black Mist get his victory?

When a Spirit by the name of Astral arrives in the Human World, things start going wrong. It starts small (like belongings going missing), but then it gets worse (like mass murders and destroyed buildings). Astral and his human partner Yuma Tsukumo must find who is behind it. But will they be able to stop the Darkness, or will they be destroyed?

Black Mist is born in a royal family, betrothed to Number 83 Galaxy Queen, but they are at war with the Barians. He spends his entire life learning how to lead a war without expecting to do so. When his father gets killed in battle and his mother gets killed by an illness, Black Mist is forced to take action early and lead the war. Will he be able to pull it off, or will he fail?
