ASMR or Autonomous Sensory Meridian Response is the nerve-tingling or relaxing response and sensation one gets to stimuli such as certain sounds or sights. As the title indicates, the anime will let viewers experience ASMR in 180 seconds. In the story, the heroine challenges her classmates to share in her hobby of recording ASMR works.

The slapstick comedy revolves around a protagonist who was reincarnated into a dummy head microphone (a microphone embedded in a fake human head to faithfully record the aural ambience). That dummy head microphone happens to be used by Yuri and other high school girls in an ASMR club, who have their sights set on the "ASMR Koushien" high school championships.

An ASMR series from Goodnight Moon. You are the main character and you meet different characters.
