UPDATE: And to celebrate all the new folks below, here's a new, more full-on trailer.
Ooops, looks like I missed these at the weekend, a trio of new(ish) character videos for Musou Stars. Given I'm currently reviewing Fate Extella, better get used to all these whack-a-mole, massed-rank, battle games. The new members of the crew include Hollow, Millenia, and Ryu Hayabusa.
More recent press in Japan also reveals that Laegrinna from Deception IV: Blood Ties, Oda Nobunyaga from Samurai Cats, plus usual suspects Lu Bu from Dynasty Warriors, and Ii Naotora from Samurai Warriors, likely with more to be added to the roster, or as DLC characters for later.
