This is a quiz app about the popular game commentator "Radaa".
A distributor and commentator who is active on youtube etc. (laughs). A man who is loved by 100%, although 90% of listeners are anti. The listeners are insulted by "smell" and "incompetence", and are basically tampered with by "Who is it?"
In addition, when recruiting endings from listeners, strange things are sent, serious MAD is made, and live-action faces are used as material several times.
The name comes from RADWIMPS. The English notation is RADDAR.
An unofficial quiz app!
