This collaboration event featured characters from the Samurai Shodown (AKA Samurai Spirits) fighting games franchise.
On the whole, this collab event wasn’t nearly as important as Cinderella Fantasy.
The two event characters, Haohmaru and Nakoruru, are so-so at best. Wind got Fugudoku (wind katana), the best wind unknown weapon to date, but many wind mains forgo unknown weapons entirely. Chichiushi (light katana) only has medium attack up, but it is a decent main hand weapon for the Swordmaster class. Problem is that the Swordmaster class is rarely played in a serious manner.
Nevertheless, I spent a good amount of time on this collab, mainly because it was a good testing ground for my burgeoning wind pool/team. I farmed two 3* wind katanas from the event because, coming from dark, two unknown weapons is standard in non-Enmity Celeste dark builds. I also bothered to get a 3* light katana because the light unknowns I do have are merely 1*.
