Prologue
Nashi was the daughter of Natsu and Lucy. She had inherited her father's pink hair, onyx eyes, and fiery temperament. On the other hand, she had Lucy's celestial powers.
Blue was Gray and Juvia's son. He had his mother's hair color and his father's eyes and ice-make powers. Unfortunately, he had also inherited Gray's stripping habit, but he only admitted showed at the very climax of a battle.
Blue and Nashi both had little sisters. Ur was almost completely identical to her mother; she had her blue hair, her eyes, her magic, her everything. And she had her mother's temperament.
Stella was a strange combination of Natsu and Lucy. She had her father's hair, her mother's brown eyes, her mother's figure (much to Nashi's chagrin) and both Natsu's fire magic and Lucy's celestial magic. She was sweet and gentle until provoked: then, she became a raging ball of fire, similar to Natsu.
And though neither Blue nor Nashi wanted to admit it, Stella and Ur both knew what their secret was: they had a crush on each other.
