大人の痴漢電車倶楽部

One day, Kantaro Daichi, a hikikomori NEET, obtains the "Adult Molester Train Club Pass", after winning a campaign that only those who paid a large amount to a major site can apply for.

It is said that during the campaign period, those who have this pass can engage in train molestation as much as they want and will not be caught.

Kantaro begins molesting two people, disciplinary committee member Naruno Hoshiguma and female teacher Ikue Suguri.
