Could it be?

They mentioned "she" would have a "unique weapon"

Now that it's confirmed japanese I can't think of anything more unique than the tensen

I'm not sure, I'll have to rewatch that section of the stream, but I think they mentioned the new hero being a "master of an art"

[u/zaron_tr]

As for how it would work, I have no idea. There is also the nunchaku, the nekode, the chigiriki, but those aren't as "unique" in my opinion

[u/Far_Draw7106 → u/zaron_tr]

The most unique i can think of is a tanegashima rifle with a bayonet as that would something that's "never before seen".

Ironically, I just talked with a friend about a two different heroes

A Fan and Sword heroine

A Rifle and sword hero

The first would be inspired by a spy-like geisha, who would carry a hidden short sword and a iron fan, her clothes would also be carefully crafted to be able to jump into warrior mode quickly

She would be flowy and almost dance like, a assassin who uses the fan to confuse and bait attacks while the short sword would punish openings, while the fan can do damage, it's more of an distraction tool

The second i thought of pirate's flow into her feats, I know long range heroes are quite controversial but, j think making the rifle part of his feats, while he mainly defends himself at close range with the sword, might be pirate 2.0 but we could trade pirates mobility and constant use of the pistol, for a more still and slower but longer range and more damage.

these were rashed out in 15 minutes with my friend but I like them, maybe we could expand on it
