Referring to Lost Song's weapon names is often highly inaccurate due to it being non-canon. Another problem about that is how there are two separate names for that specific weapon model in the game, one at Rank 7 (Ray of Grace) and another at Rank 5 (Not sure about official English name but it's from DLC Flying Sphere Slayer), further undermining the chances of a guess using the game to be the intended naming for said rapier.
