"Neither of us can imagine a future without the other, right?"
About
Sennichimae Theater in Namba, Osaka.
On stage, the two are getting laughs again today.
But once the curtain falls, they aren't just comedians.
The night road home after work. The sparsely populated dressing room. The trivial conversations exchanged while going over material. In the midst of a casually passing daily life, ties 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 conversational manzai, and they do not perform skits. A style where Haruomi delivers precise retorts to Tohru's unique, deadpan jokes. They specialize in a unique worldview that gradually shifts away from daily conversation, valuing the pauses in their dialogue.
