Besides, the Lust Demon King who cursed Catherine isn't the Phantom now. Lynn already avenged her long ago, so what's left to settle?
"You have the freedom to go to the battlefield, but personally, I don't recommend it. Your curse has been lifted, and the grass over the last Lust Demon King's grave is taller than you. Unless you have a real hatred for evil, there's no need for you to go Demon Slaying."
Lynn isn't the domineering CEO who only ever says "Woman, you XXXX", he fully respects Catherine's wishes, he just doesn't recommend she go. It's just a simple suggestion.
"Since the Demon Race invaded, our world has lost so many people across generations. Even the history book's brief mention fills a full volume. Besides having a feud with the Demon Race, I also have personal grievances. If I have the chance, I want to contribute to the anti-demon warfare."
Catherine really knows how to speak like someone who's been a mentor for over a decade; Lynn has nothing else to say.
