For centuries, Raiden Ei had searched for her sister, the echo of her laughter in the wind the only remnant of their shared past.

Across vast oceans, Raiden Makoto resided. Unaware of her origins, she lived a simple life, her heart yearning for something she couldn't quite grasp.

The sisters' destinies intertwined when a mysterious traveler arrived in Inazuma, bearing a charm identical to one Raiden Ei had given Makoto.

The charm, a link to her past, ignited a spark of hope in Raiden Ei. She resolved to find her sister, setting off on a dangerous journey.

Meanwhile, Raiden Makoto felt a strange pull, a connection she couldn't explain. The charm she always carried seemed to hum with an unfamiliar energy.

When Raiden Ei arrived in Makoto's village, their eyes met. A strange familiarity washed over them, and Ei approached Makoto hesitantly.

"I believe this charm matches yours," Raiden Ei said, offering her half. Makoto gasped, holding out her charm. When they touched, a surge of energy erupted.
