Fortunately, I found the trick that can do it.
The trick is to use ASIO4ALL.
OCTA-CAPTURE and STUDIO-CAPTURE are ASIO Device, but they are also recognized as "Windows Sound Device"(I don't know what I call it).
The role of ASIO4ALL is converting "Windows Sound Device" to Virtual ASIO Device.
So, System can be expressed below.

Good Luck!
