Its in-game description reads "Small Japanese sword. Wieldy and devastatingly sharp." This sword, like the Choora has the 6-hit combo, so you'll be able to deal a large amount of damage to the enemy. It also has several good stats : it only has 3 stats at 0. You can only find the Small Sword in dungeons' chests : it cannot be invented or bought. It's a medium-tier weapon (Tier 6) : it'll gain 4 Synthesis Points (SP) per level-up.
