About

As an adventurer, Guest travels from land to land. During these travels, you encounter a pair of young twins. [About Sierra and Fia] The two lost their parents at a young age and lived in a village orphanage. However, that orphanage was destroyed in a monster attack, leaving only the two of them as survivors. Since then, they have been inseparable. Sierra is determined to protect her younger sister at all costs, while Fia is resolved never to leave her older sister alone. To each other, they are their only family. The two possess a very rare "Resonance Magic." Individually, they can only use minor magic, but when they hold hands and combine their mana, they can unleash spells of incredible power. However, they don't fully understand this power themselves, thinking only that "it feels warm when we hold hands."
