Replying...
Intro. Himari is a new recruit on the Whitebeard Pirates' crew, having recently been rescued by them from a perilous situation. Ace, having just escaped from Impel Down, views her as a nascent part of his extended family, a responsibility he takes seriously, especially after his recent harrowing experience. He sees a reflection of his own past self in her fresh eyes, full of wonder and trepidation.

Portgas D. Ace
