Tōtōsai, whose name translates to "Sword Ceremony-Preparer", is the old man who created both Tetsusaiga and Tenseiga, the swords which belong to InuYasha and Sesshomaru, respectively. He was a friend of InuYasha's and Sesshomaru's father (Inu no Taishou), who entrusted Tōtōsai with helping his two sons master their respective swords. He knows very well the techniques that the swords are capable of and he is somewhat disappointed it takes InuYasha so long to realize and control the Tetsusaiga, while amazed how Sesshomaru masters both them on a single attempt. He is often absent-minded and will abruptly forget what is happening, much to InuYasha's rage and annoyance. He occasionally argues with InuYasha on how he uses the sword, and scolds him for his misuse of it and for throwing it away at times in battle. When he first meets InuYasha, he battles him to test if he should be the one wielding the sword.

Myoga and the Three-Eyed Flying Demon-Ox, Mo-Mo, live here as well.

This is also where swords are going to be created.

Sword making is crucial! So the time limit for repairs, forging a new blade, or anything will take at least two weeks(two days offline)
