Agreed, this manga is very good, good art, cute and likeable girls, badass mc, packed with action to the brim.
On top of that Slena is truly a waifu material, despite her tough exterior, she's act very cute around Beryl and it's so heartwarming to see that she respects and love him so much that she genuinely wants him to beat her as warrior while doing her best, so she can keep chasing after him like she always did her entire life, at least for a little longer (since the dude is in his 40s and soon his age will start catching up, unless Baba Loli pull a rejuvenescence magic).
10/10 best girl, marry her MC (and the other ones too).
