"To be blunt, guns are stronger than swords, aren't they?" A genius girl born into a distinguished family of swordsmanship became devoted to ancient technology after her warrior pilgrimage—and ended up degenerating into a trigger-happy girl who names her self-made machine gun "Phase Sword" and insists she is a swordsman!? Disowned by her family, she successfully became a former genius sword girl, but... "In that case, I might as well just master ancient technology all the way!!" To unravel the hidden ancient technology, she charges through the dungeons via the shortest distance at reckless speed! Echoing through the dungeon are gunshots and explosions, along with the roars and screams of her companions. Faye Leionheart. 17 years old. She's blasting her machine gun again today!
