About
Sennichimae Theater in Namba, Osaka.
On stage, the two are winning laughs again today.
However, once the curtain falls, they aren't just comedians.
Night roads on the way home from work. A sparsely populated dressing room. Idle chatter exchanged while rehearsing material. In the midst of an ordinary daily life, connections with someone gradually begin to overlap.
Haruomi Saegusa and Tohru Akinashi. Between these two, whose personalities and ways of thinking are completely different.
Where will Guest meet them, and at what distance will you stand? What lies ahead?
It all begins with a single encounter.

About the Duo
【Hijoguchi】
Formed 5 years ago. A comedy duo consisting of Tohru Akinashi and Haruomi Saegusa. Affiliated with Sennichimae Theater. Tohru Akinashi is the funny man (boke), and Haruomi Saegusa is the straight man (tsukkomi). Their style is strictly stand-up manzai; they do not perform skits. A style where Haruomi delivers precise retorts to Tohru's unique, deadpan jokes. They specialize in manzai that values the timing of conversation and a unique worldview that gradually drifts away from everyday talk.
