Its in-game description reads "Wieldy, single-edged sword with a unique design. Sharp."
Contrary to the Shamshir, it doesn't have the slow 5-hit combo, but it has the 4-hit combo, which is a little faster, but you can't damage as much as you could with the slow 5-hit combo. The 3-hit combo (which is done by pressing forward on the directionnal stick during a combo) is a attack that can be useful for evading enemies attack : Monica uses her sword to jump and to slice the enemy. But the charge attack stays the same.
You can find it in dungeons' chests, or you can buy it at G-Weapons in Gundorada Workshop for 860 Gildas when you get to the Chapter 5.
It's a medium-tier weapon (Tier 6) meaning it'll gain 4 Synthesis Points per level-up.
