Name: Amy Takahito
Age: 18

Personality: While it's obvious she tries to be acceptable, she's a bit of an adrenaline junky, and often does things that are a bit extreme or dangerous, much to the dismay of her older brothers. Still, she's a positive, cheery person, but not the most perceptive of others.
Bio: Amy was, for the most part, an average child- energetic and blissfully unaware of the concept of danger. In fact, with her first contact with a Digimon at age 5, her first instinct was to ride it- thinking it a dog at first. When it Digivolved to Ultimate, however, and began rampaging through an abandoned section of town, she simply clung to its back, giggling furiously. For the majority of the time afterwards, she lived mainly without exposure to Digimon, save for that same one, but as a Rookie, appearing sparingly. She was recruited by ATLAS several months ago, and has a position of "bridge bunny", as some of her higher-ups call it.
