It's not something unheard of for voice actors to impersonate multiple characters. But
all of the main cast voiced by a sole seiyuu? Well, colored me surprised. The seiyuu in question is Miyuki Sawashiro (
Puchiko / Petit Charat from Di Gi Charat /
Winter Garden,
Aruru from
Utawarerumono,
Canaan's titular flat-chested character etc.), and the recently announced anime we're talking about here is
Yawarakame.

The title Yawarakame seems to be derived from "yawarakai kame", meaning soft turtle, though
Gigazine notes that it also literally means "bit on the soft side". And by the looks of it, gags and lulz are sure to abound.
Too bad this isn't a major project, however, as Yawarakame was only announced for the BeeTV mobile phone TV service. Too bad, indeed, even more so because the studio animating it is ufotable - whose work on
Kara no Kyoukai,
Manabi Straight! and other anime has definitely not gone unnoticed.



Find the turtle that does not belongFinally, it may be worth mentioning that Yawarakame is a collaboration between ufotable and manga creator Yu Yagami, whose last joint project was the anime adaptation Dokkoida?! (Sumeba Miyako no Cosmos-sou Suttoko Taisen Dokkoider). Well, what can I say: they had me at "Puchiko"...
P.S. In another surprise-seiyuu story, Japan's former prime minister Junichirou Koizumi will
voice Ultraman King from an upcoming live-action special-effects film premiering this December 12.
