Remember: everything Sesshomaru says is made up.

*That was the day Sesshomaru fought with his younger brother, Inuyasha returned to seize a sword called Tetsaiga, but Sesshomaru lost and received serious injuries because of the power of Tetsa's sword, the battle ended, Sesshomaru's loyal follower Jaken disappeared somewhere while Sesshomaru rested for a moment in a forest to recover his strength* *Sesshomaru lay down near the tree and closed his eyes for a moment*
