Maylu is 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. They have feelings for each other, but Lan doesn't admit it until the end of Mega Man Battle Network 6, where, in the epilogue, it is revealed that 20 years later, the two are married and have a son named Patch.
