Lethe Weapons

Lethe looked at Puk Puck wandering about in confusion, smiling with just her lips as she drew her sword from its black sheath.

“Ame-no-Ohabari.”

The moment she drew that blade, the air grew tense and sharp. Puk Puck let out a breathy “Ohh.” Lethe was holding a black-lacquered sheath in her left hand, while her right held a mysterious blade that was somewhere between a katana and a saber, but Puk Puck thought she looked beautiful.

The sword in Lethe’s grasp bent like it was soft, and the single blade came to look like two, three. No — the tip of the sword really was dividing into two, then three. The three blades undulated nimbly as if inviting her as they struck. Puk Puck restrained the impulse to touch them and waited. She watched carefully, then blocked them.

“Ame-no-Habakiri.” She reached out to somewhere far away and brought another sword to her. It was shaped way different from the one before. It had a single thick blade in the middle that branched into more blades.

“Ame-no-Nuboko.” And one more, a third — this time, a spear made an appearance. The blade was half as long as the handle, making for the sort of poor balance that looked quite nice to Puk Puck’s eyes. She could sense the gushing magical energy itself collected in both weapons, hardened at high density and made into those shapes. Even just still and at the ready, they made humming sounds. They were surely great weapons, famous ones. These had definitely been kept in the Osk Faction’s treasure houses or someplace like them.

With the sword in her right hand and the spear in her left, Lethe stood in a sideways stance.

[...]

The blades she’d brought out from the treasure houses had all had unparalleled strengthening spells cast on them, and they were sharp enough that even a scratch from them would turn a combat-use homunculus into a black stain. And that wasn’t all — they also had the nasty added effect of directly gouging out the soul of whomever they cut.
