What episodes do firiel and roux kiss in?

There is no anime or show with characters named "Firiel" and "Roux" that are known to have a kissing scene. It's possible you're mixing up the names or the show.

To help me identify the show and the characters you are referring to, could you please provide:

* The name of the show/anime:

* A brief description of the characters: (For example, their appearance, personalities, or roles in the story).

With more information, I can assist you in finding the answer to your question.
