What were you fighting for?
Rufus already had an answer to that question; it wouldn't even take time for him to answer such a simple question. However, ever since Acheron Roseberg asked that question, Rufus couldn't help but think about it.
It wasn't that Rufus was questioning his own agenda, nor was he thinking about it to judge Acheron. In fact, the more he thought about that question and what drove Acheron this far, the more Acheron's action made sense. Not everyone was like Rufus and Samael's relationship.
Acheron and Zero's relationship didn't stem from friendship. It wasn't anything like that. From what Rufus heard from Lilou, Acheron treated Zero as his own. Like a parent who would do anything for their child, even if it was wrong. Rufus trusted Lilou, but now that he was fighting Acheron, he had confirmed that.
Acheron's loyalty wasn't just that of a hellhound, but he truly cherished Zero.
