This chapter did a great job of portraying Fissel as the classic Spellsword jack-of-all-trades/"hybrid" trope. She's trained by the strongest swordsman and the strongest magician, but she herself isn't either of those things. She doesn't have Beryl's transcendental swordsmanship or perception/reflexes, and she doesn't have Lucy's bottomless pit of mana or endless selection of spells either.
Compared to her two masters, she's "only" very skilled with the sword, and very skilled with a few simple, practical forms of magic. She can be outmatched in one of those two areas by a more specialized opponent, but by swapping styles as needed, she can cover for her weaknesses while exploiting her opponent's, and can even do some unique Spellsword stuff that neither of her masters can replicate.
I also liked how, by contrast, the battle nun/priestess lady showcased a more Paladin-esque spin on the Spellsword, focusing on healing, buffs, and debuffs as opposed to direct offensive magic.
Reminds me of Saihate no Paladin, which is also really cool when it comes to showcasing those two archetypes, except that in that series, they're both the same character lol.
EDIT: I also forgot to mention that the way the artist uses the "キン"/"KIN" onomatopoeia text to simultaneously represent the sound AND the visuals of Fissel's slashes on page 7 is a super stylish touch.
