While Rezen doesn't feel guilty or at the very least not too guilty, it would be a lie to say that he doesn't feel bad for what he did
He has his reasons and he would do it again if he has to but it doesn't mean that he doesn't care about Claude. That man is very kind and Rezen was a previous recipient of that kindness
If not for the unfortunate circumstances, Rezen would never betray that kind brother. He didn't expect that he would meet someone that has the same kindness as Claude does
While the personality and aura of the two are completely different, the kindness in their hearts is completely identical based on what Rezen could sense
This helped lessen Rezen's fear and after calming himself, he nodded his head
"I-I'm alright. Thank you for your help" Rezen said politely while bowing his head a bit
If not for these people, Rezen might have died today. Now that he is safe, Rezen could sense the rank of the now-dead magic beast
