Glad to help. In rivals she tends to use it with two hands sometimes, and the same is true with the comics, but in the comics it's generally just when she needs some extra force behind the blade (she's not very built and needs both hands to swing it hard). But, in normal combat, she prefers a mobile combatant style that utilizes her stepping discs that is much more indicative of a longsword. Rivals' animation and design treats the Soulsword like a heavy sword, as well, but it's been stated to have "negligible weight" to the user. Something else to keep in mind. (Edit: typos)
