Who are Tohoku Kiritan and Zundamon?

Tohoku Kiritan and Zundamon are characters created by a Japanese company, SSS LLC , in 2011—the year of the Great East Japan Earthquake—to support the recovery and revitalization of the Tohoku region.

Zundamon, in particular, gained explosive popularity in Japan after a free-to-use synthetic voice was released in 2021, becoming widely known through YouTube voice commentary.

Sengoku Voxel Castle  is a fan game featuring these characters, but it is designed so that you can fully enjoy it even without prior knowledge of them.

If you’re interested in Sengoku-era city-building games, or Japanese-style RTS, we highly recommend giving it a try!

Tohoku Kiritan (Age 11)

The youngest of the three Tohoku sisters.
Her older sisters are Tohoku Zunko (17) and Tohoku Itako (19).

She carries the “Kiritan Cannon” on her back, inspired by kiritanpo, long style rice cake.
Her birthday is February 13.

In this game, she is caught up in Sengoku-era warfare and becomes separated from her sisters.
Together with Zundamon, she escapes to an uninhabited land, builds a new village, and fights to survive while hoping to reunite with her family.

Zundamon (Human Form)

A humanized form of an edamame fairy.
Age unknown. Birthday: December 5.

She loves zunda mochi and can transform into a Zunda Arrow.
In official novels and comics, she often splits into multiple copies—and many Zundamon appear in this game as well.

In-game, Zundamon supports logistics in your town and fights alongside Kiritan as a reliable ally.
