Age: 19 Orihara is a young assistant who worked with Ashirogi Muto on "Run, Daihatsu Tanto!". He is a very energetic and cheerful character that tends to get loud due to his excitement, may it be about work or something else. When Takagi and Moritaka decide to quit the series, he offers to keep working for them without payment, because he still wants to learn from them.
