DL6 incident: At that time, all three people in the elevator were in a coma due to extreme lack of oxygen. In the past, Ashrut had an argument with Shin Mitsurugi before she went into a coma.

Gregan fell at the foot of Met with a gun (when I was a child). Meet (already in a state of high hypoxia) In order to prevent disputes, throw a pistol at two people.

The pistol went off and hit the hunter on the shoulder right outside the elevator. All three were unconscious, and the hunter screamed, making Yu Jian mistakenly think that he had shot his father.

(Shin Mitsurugi didn't see it himself, so when the psychic said it was Grey Root, perhaps to cover up his son, he fainted only when he heard a gunshot. )

This is the time to electrify the elevator door, open the hunter, go in and pick up the pistol, shoot Shin Mitsurugi without hesitation, wipe off the fingerprint and leave.

The bullet stays on the shoulder until it is taken out.

At that time, when the killer confronted Shin Mitsurugi, he was corrected by the other side and produced a false certificate, which made the perfect shadow bear a grudge.
