Powered Armor: Both Gerard and Jin-Ho come equipped with these a la Iron Man in their climactic confrontation with the protagonists. The Infinity has an Infinite Stratos-sized Powered Armor in the final battle in Blue Starlight.
The President's Daughter: Three of them: Akane, Ashley, and Nana. Though it's Ashley that fits this trope the closest in its literal sense, with her being the daughter of a high-ranking US Air Force officer.
Weissdrache / Stephan Bleumer (technically, a clone of the original)
Weissdrache is the CEO of Solty-Tech Industries whose plan is to abduct Akane. It is eventually revealed that he intended to do this to extract her Herald-based energy and convert them into a power source for his Kill Sat, the 'Starduster'', and blow up the planet - himself included.He constantly desired the approval of his father, who only sees him as a trophy. After learning about his being a clone of the original, he calls him out... with a plasma beam to the head.
Adjusting Your Glasses: Type 3. He does this even in combat. Starting in Blue Rainbow, this doesn't trigger the glare as much.
Calling Your Attacks: Played with. He says absolutely nothing when he himself attacks, while he punishes opponents who call out their attacks by attacking them as they are just to call out their attacks.
Ten years ago, she was the only American member of a local martial arts dojo in downtown Brooklyn, with everyone else being of Asian descent. In line with the trope, she was fast in learning the martial arts, earning her disdain from every other member - except one, a Japanese girl about the same age as her. Then, there was a gang attack on the said friend of hers - by white extremists, no less. In other words, her guilt over not being able to defend her only friend in the dojo, combined with the harsh treatment of every other member, made her decide to leave and seek her own path.

One of the "Agents" of the Rapid Rescue Force, hailing from Japan. Sayaka is a college law student who takes up her R.R.F. duties as a personal quest to find the true meaning of justice.Akane later learns via Pure Heart that Sayaka had this viewpoint after the death of her sister, Kyoko, at the hands of the Yakuza.
Asian and Nerdy: A variation. She does not follow the "Asian math wizard" stereotype; instead, she studies law.
Knight Templar: Displays this during Blue Eyes, and this means she is absolutely unforgiving with evildoers - thus putting her into a sour relationship with Rachelle, who was a former member of a white extremist group. She became this after her parents sold her as a sex slave in exchange for drugs.
She gets better (i.e. more forgiving) during the events of Blue Rainbow.
