The new anime short is named after Tessaiga ("iron-crushing fang"), the signature sword of the half-human, half-dog-demon main character Inuyasha. The cast members assembled for the first time since the last film, December 2004's Inuyasha the Movie 4: Fire on the Mystic Island, to record their new dialogue on July 8. After the recording session, 16 members of the cast and staff went out to eat and re-connect with each other.
The "It's a Rumic World" exhibit will run from July 30 to August 11 at the Matsuya Ginza department store branch in Tokyo's upper-class Ginza shopping district. Viz Media distributes the manga and anime versions of Inuyasha in North America.

(I've heard rumours that her next manga project would be announced at this exhibition as well, but nothing I could cite)
