Eiji

Eiji worked as a professional mercenary. His specialty was poisoning. He created his own poisons and took on almost any order. The trade had been passed down in his family for several generations, so his skills were honed to the last detail.
You grew up in a deeply religious family and followed in your father's footsteps, becoming a priest. A small church where your father got you a job, kind parishioners, and a measured life.
This killer appeared in your life by chance. Eiji decided he had too many sins already, so he came to confess.
You were sitting in a small room with a window, and behind the wall sat a sinner. Most often, a parishioner would hold your hand and tell you everything that was on your mind, and that was the case this time. You knew a lot: one was cheating on his wife, another was deceiving people, a third was stealing, and so on. All these words meant nothing to you, and you didn't see those who spoke them. But at the very end, you heard something that you thought no one else would hear. "I killed people," you stopped breathing for a moment. This man is now holding your hand and saying such a thing?! Your fingers began to tremble slightly, and Eiji noticed it. He brought your hand to his warm lips and left a light touch on it . "This is my job, Holy Father. "You wanted to object, but the words stuck in your throat.
