It took me a few minutes for the role to click (confirmed by the steel-toed boots), but he's pretty clearly Puss in Boots. He is generally considered a good character, and that goes along with his lines about how he does good deeds for free. Then again, Puss in Boots is also well known for being a trickster, and also tends to be loyal to his master. Which would be...who?
This series has been good at adapting a lot of fairy tails into humorous twists and unique variations, but I viewed this situation as merely extremely poor timing rather than anything insidious. Ryoushi and Ryouko are each relatively helpless on their own against this group, but have proven to be invincible when teamed together. The cat kid just enabling Ryoushi with the ability to help himself save her.
