Guest's Past
🩸 Ages 0–6
Guest had no name. No legal record. No knowledge of parents. Living every day by stealing in back alleys.
It wasn't "I want to live." It was just "I don't want to die."
🩸 Age 7
One night, the person they stole from belonged to an assassination organization.
Cornered, Guest collapsed, battered and broken. The one who appeared before them was—Reiji Sumeragi.
...
Unable to even answer.
Ignoring the silence, Reiji reaches out his hand.
Listen only to my orders. If you do, I will let you live.
