Nicolo, a former Marleyan naval soldier deployed in the first survey fleet to Paradis Island after the failed Paradis Island Operation, is captured by Eldian forces and reinvents himself as a chef within their military. Initially scornful toward Eldians due to Marleyan propaganda branding them as “devils,” his prejudices erode through interactions with the Survey Corps, especially Sasha Braus, whose spirited appreciation for his Marleyan cuisine sparks a transformative bond. Tall and lean with blond undercut hair, Nicolo shifts from a Marleyan uniform to a cook’s attire, his culinary expertise defining his role on Paradis. Sasha’s infectious enthusiasm for his dishes forges a connection that reshapes his worldview, deepening into unspoken affection. Her death during Liberio’s battle fractures this bond, unleashing his buried rage. Confronting her killer, Gabi Braun, he nearly murders her in a grief-stricken frenzy and later urges Sasha’s father to exact revenge—a violent lapse tempered only by the Braus family’s merciful refusal. Guilt-ridden by their forgiveness, Nicolo embraces reconciliation, advocating for unity. His strategic insight proves vital when he exposes a critical suspicion: Zeke Yeager’s spinal fluid taints wine meant for Paradis’ leaders, deduced from Marley’s past tactics and Yelena’s orders to target elites. Though unverified, his warning halts consumption, thwarting a Titan transformation plot and cementing his loyalty to Paradis despite Yeagerist skepticism. Post-Rumbling, Nicolo stays entwined with the Braus family, aiding their survival by guiding them to safety, shielding them from Titans, and provisioning rescue missions. Three years after Shiganshina’s liberation, he stands beside them, witnessing Jaegerist ceremonies with visible disdain—a silent testament to his rejection of vengeance. Nicolo’s arc traces guilt, shattered prejudice, and redemption. Once a loyal Marleyan, he bridges divides through empathy forged in personal loss. His bond with Sasha and volatile clash with Gabi underscore how intimacy can unravel ideological enmity, positioning him as a reluctant advocate for peace in a cycle of war.
