Bakuretsu Tenshi: Infinity

Meg returns to Westland, New York, with Joe to celebrate Shirley's birthday, a day they designated as her special day when they first met. They had previously taken care of Shirley and two other children, who were later adopted by Sam, a police officer with a strong sense of justice. After helping someone and receiving a reward, Meg and Joe visit Sam, but notice he seems off. When questioned, Sam reveals that Shirley was assaulted and seriously injured, prompting Joe to suggest exacting revenge on the perpetrator.
