With a theatrical anime adaptation in the forms for the two volume light novel series High☆Speed!, it’s really no surprise that Kyoto Animation will also be doing a manga adaptation as well. The announcement comes with a promotional spot for it that you can see below with the story written by Kouji Ohji with artwork by Shiori Teshirogi.

The light novel comes from Kouji Ohji with illustrations by Futoshi Nishiya and served as the original inspiration for the anime series, but the differences are that the anime upped the characters to high school level while the novel had them in junior high. The theatrical anime adaptation is expected to serve as a prequel to the TV series and breathe a little more life into the property for fans.
The original novel was written by Kouji Ohji back in 2011 and it received formal publishing in 2013 and 2014 via Kyoto Animation, who also produced the anime series. A manga adaptation of this project is also underway with Shiori Teshirogi set to illustrate it.

After achieving victory, each of the boys went their separate ways.
