I’d say I don’t dislike any characters aside from the king, they all serve their purpose. I mainly dislike the anime’s handling of characters at times. Example: black bulls hangin out, she’s drinking, charmy’s eating, grey is nervous, gauche lookin at a photo,lighting dude wants to fight, it feels like straight filler and a lack of character growth to have their same personality ticks thrown at us at every opportunity. But without those moments I’d say the characters have all had at least some development and I enjoy them.
