We started with one jewel shard but after three days of traveling we ended up finding two more shards. When looking for they're forth shard, a robber starts robbing Inuyasha's father's grave. Later that night when the moon is full, Inuyasha and I are talking out near a tree when he falls off, pushes me down, and tells me to be quiet. In the night sky, up in the clouds, a carriage rides. Inuyasha gasps in shock as the face of the woman inside the carriage turns out to be the reincarnated form of his mother. All of a sudden, a giant ogre grabs the carriage smashing it. After the dust settles, Inuyasha's mother is all that remains and she is trapped by chains, which are held by a mysterious person. Inuyasha gasps when he says that the person holding the chains is his older brother, Sessho Maru. He had been all over the globe searching for their father's grave and hadn't found it. Sessho Maru sought Inuyasha since he was the guardian of the grave. After a small battle, She found out that the stone that held their father's grave was in Inuyasha's left eye. She tore the stone out, and with a quick swipe, tapped the stone, which was now on the ground, with the staff of heads. The guy started speaking and a black vortex opened up engulfing Sessho Maru in its vastness. Inuyasha and I jumped in following Sessho Maru and chased him down into the belly of their tomb. There we found a sword that looked corroded. Sessho Maru tried several times to pull the sword out but a strange barrier prevented him from holding it. Inuyasha tried his hand next and failed to pull it out but had been able to actually hold the sword. Finally after Inuyasha and Sessho Maru battled a bit, I tried my hand at removing the sword. I succeeded in pulling it out but drew the attention directly to me. Sessho Maru transformed to her true self when I gave Inuyasha the sword and the battle raged on. Finally as a last resort, and after I had escaped death a few times, Inuyasha told me that he was going to protect me. Just then, the sword sprang to life and transformed into the tooth of their father. Inuyasha sliced off a limb and badly injured Sessho Maru in doing so. Sessho Maru fled afterwards with his henchmen following.
