Alright, so at least the girls are acknowledging his sudden power gain. Does he have a cheat skill or something?
"The current him, has the strength comparable to us, world class adventurers."
"Sure he may not be gifted, but he has come a long way..."
That sounds a little contradictory to me.
It was annoying me that Narsena kept it a secret from him even after learning he still remember who she was and now Raust overheard them. It'll annoy me even more if he decides to keep that a secret, like I feel he'll do. Both of you just come clean already.
WTF, sudden sleazy pickup-artist encounter, fantasy world edition. After breaking the first guy in half I expect she can finish the job on her own. Y'know, because she's supposed to be a competent melee fighter. I'd hate it if she's suddenly in trouble against backline dudes (a mage in close combat against a martial artist?) and will need the male lead to rescue her. (this actually seems very possible given the (low) quality of the manga so far...)
