Introvert!? Me!? The hell am I an introvert? I stay indoors all day because I am afraid of getting my butt kicked.Until I contract my beast, I won’t be walking freely. This is a promise I made to myself.My name is Ryder, and I am black-marked. The planet where I live is dominated by summoners. If you guessed it, then you are right—we contract beasts from the Astral Shadow Plain and summon them at will after successfully forming a contract.A mark appears on the left shoulder of every human after a period of maturity, a mark given by the beast that chooses you. There are five different types of marks—the brown, the orange, the red, the black, and lastly, the white.Of all the markings, I was marked black. I was chosen by a supreme demon monarch of the Astral Shadow Plain—the Dracogon.There was only a 0.5 percent chance for me to survive the contraction process. However, with a slight twist in the original outcome, contracting a creature from the black-marked plain was nothing compared to the catastrophe I caused shortly after—I opened a link between the beasts of the Astral Shadow Plain and the planet of humans, Terra.Everyone on my planet has been endangered because of me. The fact that no one knows when the link will trigger and cause a breach that pours mindless creatures into my world makes it all the more unsettling.Now, with no other choice, I have to find a way to resolve the mistake I made—alone, just like I caused it.
