``Let's Sing! Chargeman Ken! Music Festival'', a participatory cinema concert in which a professional orchestra will seriously perform the anime ``Chargeman Ken!'' and allow voice and cosplay, will be held on June 20th at Kitatopia Sakura Hall in Tokyo.

"Chargeman Ken!" was broadcast in 1974 and has gained cult popularity through video distribution services. At the ``Chargeman Ken! Music Festival'', in addition to live music by the professional group ``Charkestra'', episodes from the work will be screened on a large screen. The audience can say lines such as "Dr. Bolga, please forgive me!" according to the scene. Noboru Sato will also be on stage at the concert and will read Ken and Hoshi-kun's lines live. Call-and-response projects with tongue-lashing themes are also planned. There will also be a part where you can take pictures with your smartphone and share them.
The scheduled performances are Episode 4, "Mysterious Beautiful Boy," Episode 16, "Murder Record Horror Melody," Episode 23, "Horror! Psychiatric Hospital," and Episode 35, "Dynamite in Your Head." The note also states, ``There is a possibility that changes may be made based on the surrounding atmosphere.'' Producer Koichi Nishi sent a ``detailed message'' saying, ``Due to various circumstances, this is a last-minute challenge that may be the last time we will be able to hold an event on such a large scale.'' Tickets are on sale at teket. In addition to general tickets, ``Izumiken tickets'' for 10-year-olds are also sold for 10 yen.
