"There’s no way I would know with those huge boobs!"
Miyuki is the young girl has brown skin, a black two ponytail with the curly hair it has a pink ribbons which over by her sides and she had a bandage over her left cheek in her side. She wears a white tank top with the purple, pink and light yellow jacket and light pink heart and her back side. She wears a light green long pants, a black belt, a dark green, silver and black boots. She also wears a purple glasses. He has a chest that Dan JD describes as "huge."
Miyuki lived with Dan until her family moved away during their childhood. She and her grandfather returned in the first episode as a well-endowed teenager and a skilled mechanic. Upon her return, she gives him and teaches him how to pilot a Big Foot.
(She's 17 years old)
She cares for Dan and his team's Big Foots, something she does happily, as it gives her more work to do (and get paid for). She also has been shown as having deep feelings for Dan despite his obliviousness. Later, she redesigns the team's BigFoots, making them more flexible and agile than before, enough to create an afterimage.
Though not a Basquasher, she is still an irreplaceable part of the team, constantly fixing and upgrading all of their BigFoots. Though she has feelings for Dan, she steps aside once Rouge comes into the picture, and accepts their mutual attraction.
She did not participate in the Legend Tournament, but she did go with everyone, and did the finishing touches on the BigFoots. Her upgrades were overwhelming; the shoes that Haruka made for Dan were burned off after he pushed the BigFoot to its limits. In the aftermath, she and her grandpa continue to be mechanics and are seen working with an orange Big Foot (it is highly probable that it is Dan's).
