Seriously. Check out
her entry on the 4gamer wiki (google translate may be necessary). Besides her archery, the Elf can attack with kicks or daggers. Kicks are unlimited use, while daggers are an equippable item with a limited number of uses. (I'm not sure how many uses, exactly-- the table says level 1 daggers get 3 uses, but the text box says 10 attacks per book, so maybe that means level 1 lets you attack 30 times with a dagger? Need confirmation from someone with the game.)
As for skill upgrades, kicks get a boot upgrade (more damage) while daggers get more uses (by upgrading the dagger skill itself), a backstab skill, and the ability to be enhanced with poison or fire damage.
By the looks of it, you
can make a ninja elf if you don't want to use ranged attacks.
