Serpico

セルピコ

Serpico serves as Farnese's companion and, unknown to her, is her paternal half-brother. While serving the Holy See, he held the position of Herald for the Holy Iron Chain Knights.
When aggressive, Serpico contradicts his meek appearance, resembling a fox through his shrewd observation and rapier speed.
Despite enduring childhood abuse from Farnese and being forced to burn his own mother at the stake, he cares deeply for his half-sister. Serpico has been her servant since she discovered him beaten on a snowy street more than a decade ago.
Serpico's relationship with Guts has long been marred by animosity, largely due to the dangers that inevitably surround Guts and anyone he admits to his Band. Following a duel in the underground pillars of Vritannis, Guts spared his life. Their bond has since rekindled, and Serpico has learned to trust Guts to protect Farnese when he is unable to.
Serpico employs two items blessed by the wind spirit Sylph to fight alongside Guts with tolerance: a rapier capable of generating razor-sharp gusts of wind, and a cloak that constantly creates a swirling vortex around the wearer, which can deflect projectiles, assist in jumping, and slow falls from great heights.
