I think I found a (SPOILER-Saber)...

But I'm not entirely sure...I can't read the Kanji, but I can see that the last part is "Seiba"

It is red just like Red Saber, and its elemental is Drain, sadly it doesn't have a photon special. Anyone know if you can add photon specials to weapons in this game?

Is it the Aka Seiba?

Also, I don't think there is a way to add photon specials to weapons.
