Kenzaki was naturally born with heterochromia and with an unnatural blue streak in her otherwise black hair. She hides both of these features when she's at school, using a colored contact to cover up her yellow eye and a hairpin to cover up her blue hair highlight.
Kenzaki Ameri was born with a full set of superpowers for reasons that are still unknown to her. Those powers include:
Superhuman strength
Invulnerability
Flight
Super speed
Super breath
A right eye that can see into peoples' hearts
A left eye that can see things that are miles away and see through walls
A sixth sense that detects evil nearby
In terms of physical strength, Kenzaki is so strong that she can easily blow other superhumans away with a single punch using only a fraction of a percent of her full strength. Her invulnerability has no known limits. She once took a direct hit from a bomb that was twice as powerful as the strongest nuclear weapon ever recorded, and it didn't even scratch her.
