Ichigo, tough Yanki biker chick, rides a pink bike. With zero self-consciousness about it looking girly or wussy.
Momoko showing up at the end to save Ichigo's ass. Visual cue: girl in frilly Sweet Lolita clothes (slightly bloodied/muddied) facing down a pack of Yankis armed with tire irons/baseball bats/swords, all because they dared to threaten her friend, and then they go riding off into the sunset together, each admitting to the other that they basically made up a pack of lies to fool/intimidate Ichigo's gang of Yankis into letting them go. Epic.
