[Kunoichi Awakening] Vengeful Blade

A Sonan woman did stay in our village. But she died long ago from illness. The poor woman... She was still so young. Although she came from a different clan, we buried her in Stonetail Wasteland. Climb up to the highest point of Stonetail Wasteland and you will find the grave. She had an unusual weapon. A kind I've never seen before around here. Seemed like it was very precious to her, as she'd polish it every single day. She also spoke very little, and always kept to herself. And so, I tried to bury that sah chakram thing with her, but for some reason, it just wouldn't budge. As if something... some force lay within the weapon itself.

Looks like it's the grave the Kusha villager was talking about.
