Who voices Sachi Umino in A Couple of Cuckoos? Love her husky voice…

One of the many nice things about the recently premiered rom-com anime series A Couple of Cuckoos (aka Kakkou no Iinazuke in Japanese) are the voice actors.

Actors like Akari Kitou who plays Erika, and Kaito Ishikawa who voices Nagi.

Just about my favorite actor in the series, however, is the actress who voices Sachi Umino — Nagi’s non-biological sister, and the biological sister of Erika.

An actress who has not yet been featured in very many scenes, but hopefully that will change.

Because, come on, her husky voice is so darned cute, and the way she portrays teenage angst is adorable.

So, who voices Sachi Umino in A Couple of Cuckoos? And is she an actress you will have heard in many other popular anime series?

The voice actress who plays Sachi is Konomi Kohara (aka 小原 好美, Kohara Konomi).

Kohara was born in Kanagawa Prefecture, Japan on June 28, 1992, so will be 30 years old next month.

Yep, ‘Akane’ turned out to be a lucky name for her.
