 * Age Count:
 * Born in December 31, 1963
 * 1975: 12 years old (BZ Final Chapter)
 * 1998: 35 years old (Beginning of SK manga/2021 anime)

Through Harusame

 * In the SK manga, Harusame never returned to Amidamaru after his and Mosuke's death 600 years prior to the series, and no story was filled to implicate the katana's whereabouts before it ended up rusted at the museum.
 * IN BZ Chapter 12, it appeared in Anna I's possession who claimed from its owner "150 years ago", hence the different samurai soul portrayed other than Amidamaru, implicating it somehow ended up in another samurai's possession after the daimyo.
