Description
Amarello Berge operates as the yellow Sword Eyes of Darkness, posing as Yaiba's ally while clandestinely safeguarding Grenada. Her worldview fractured when her father—a disgraced Red Army rebel—faced punishment, eroding her faith in divinity and driving her to shatter the jewel staff gifted by Galaxy Watanabe. This act severed her maternal ties to the Sword Eyes, though she forged new purpose through Grenada’s protection.

She infiltrated Megallanion to negotiate Stinger armies’ subjugation under King Megalla II, retreating after clashes with the Sword Eyes of Light yet persisting in covert missions. These included engineering Grenada’s prison escape and dueling adversaries like Haqua and Brau. Her yellow Holy Life deck dominated battles, deploying The EvilSacredBeast Chaos-Pegasuros to drain foes’ vitality while rejuvenating her own.

Her loyalty to Grenada stemmed from unraveling his shadowed identity and their shared history interwoven with Galaxy Watanabe. Though initially compliant with Yaiba’s regime, her defiance grew until decisive defeat triggered banishment. She later influenced pivotal events, participating in the Sword of Judgment ritual and confronting Kizakura in combat.

A reckoning came during her reunion with Galaxy Watanabe, who unveiled the repercussions of her past. Embracing this clarity, she adopted Grenada’s jewel staff as a token of rebirth. The epilogue revealed her marriage to Galaxy Watanabe, their postwar life defined by managing a Battle Spirits shop—a quiet counterpoint to former battlegrounds.

The manga adaptation omitted deeper exploration of her origins, relationships, or combat engagements. No additional media portrayals exist within documented sources.
