Mob Psycho 100 is a show many people are looking forward to this summer, and due to an update to the website, which includes a new key visual, we can know exactly when the weekly episodes will air on Japanese television.
On July 11th at midnight (or July 12th, however you like it), Tokyo MX will broadcast the first episode, followed by Yomiuri TV, BS Fuji and Tele-Asa Channel 1. Both Tokyo MX and Yomiuri TV will broadcast a special program one week prior, on July 4th.
Mob Choir, a group without any information about them, is responsible for the Opening song “99”, which will also be released as a single CD on August 31st. The ED is being done by ALL OFF, who worked on the OP’s for Heavy Object before.
I’d assume that Mob Choir is going to be comprised of some of the voice actors for the show, as this doesn’t happen too rarely.
