Looks pretty good (visually). But in terms of gameplay, this unit is not for me. Of course, tests will show, but most likely it will be playable as an opener for a cleave or possibly a control. In addition, in the current meta there are units (Violet, Rem, AoLA, etc.) against which it will be difficult for him. And the requirements for his gear (opener) will be quite high. So I'll wait for the reviews, but I'll probably skip this character.
I was much more interested in Zahhak, who appears in the history of this hero. Also, I think it would be interesting if Ran used different swords. Something like stances, or simply each skill is a different sword. For example, attacking with a red sword would use a fire element.
