It's possible the band was also formed by Yasu. Nobuo Terashima was fan of this band then, or more precisely huge Ren fan. It was disbanded due to members lost interest to play together, around the time when Nobu was Year 2 at High School (17 years old, and Ren then 19) . After that Ren said that he doesn't want to play with random guys anymore. So Yasu and Ren suggested to Nobu to become guitarist in their new band, then they got Nana to be their vocalist, and thus they formed Blast.
At least once Ren made Nobuo Terashima sell tickets for Brute's performance (Nobu was Year 1 in High School (16 years old) then). Nobu went to see them too, with his friends, and that's when he decided that he wants to join a punk band as well.
