One: A Realistic Kind of Dream

Once upon a timeline -cough-Canon-cough- Hachimitsu Hachiko died as a baby during the Kyuubi attack. Its malicious chakra sent the wee baby girl into a coma where mentally she died and eventually her body gave out.

However that is not the case here. In this timeline, Hachiko's body woke up but her mind/spirit/soul, what ever you want to call it was not from the shinobi world. [Self-Insert]
