Ten years ago...

Somewhere...

April was seen playing with her older sister, Nemissa, a game of catch.

"Good catch, Sister," the latter exclaimed happily.

"Yes, I am good, Nemissa," the former replied back.

Those were good times.

One day, while walking all by herself, April stumbled on some brown-haired girl trying to plucked out a weed.

"Don't worry, I'll help you," she said as they plucked out a weed together. "Now, what are you doing here?"

"I was just picking some flowers for my school project," was the reply.

"Well, you shouldn't done things on your own so much; otherwise, you'll lose, but now now. Someday."

"Oh, sorry about that."

"Don't worry about it. It's okay."

"Oh, my name is Hitomi. Hitomi Tono," said the brown-haired girl.

"I'm April O'Neil, but you can call me April," April replied back.

"Good to see you, April. Can I be your best friend?"

"Sure, why not?"

It is then that they hold each other's hands as a sign of their friendship being born. Of course, Nemissa didn't took it well, and that became a reason for her and April's sibling rivalry to be born.

"Remember these words, April... Never give up," Hitomi stated.
