Blush

Blush is a general in the U.S. cavalry and a member of the Syndicate. He murdered Fino and Yaghi’s parents when they refused to give him information leading to the “treasure,” or Zodiac Gun. He had pretended to be wounded and allowed the family to nurse him back to health so they would open up to him about the treasure. ~!When Cavanaugh steals the Zodiac Gun from him on their way back to New York, Blush is furious that she is stealing his reward and tries to shoot her. In the midst of the ruckus, he disappears and isn’t seen again except as a silhouette at the end of the story. But Fino and Alternate are still determined to find him.!~ Source: manga
