During the epilogue set 20 years after the events of Mega Man Battle Network 6, the final game in the series, it is revealed that Mayl and Lan got married and are living in Lan's old house with their son Patch.
Mayl's parents are not seen in the series, but in Mega Man Battle Network 5, one can see a Vision Burst set 11 years in the past, where it is revealed that her father is Netopian.
Mayl is as an optimistic and smart character, whose maturity often keeps the bull headed Lan out of trouble. Throughout the series, she attempts to show Lan that she can protect him, just as he has protected her many times. However, it usually results in Lan saving her and Roll from danger.
