Brute was a punk band that Ren Honjo and Yasushi Takagi played in, before Blast, when Ren was still in High School (Year 3 at list). Other members except Ren, were older than him and outside of his school.
Possibly this band was also formed by Yasu. Nobuo Terashima was fan of this band then, or more precisely huge Ren's 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 list once Ren made Nobuo Terashima to 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.

Was a guy who broke all rules, had no respect for anything, and can finish a whole bottle of beer while playing.
Had been gave out his LOVE to fans that need it.
He was only one in the band who looked normal (still had hair at the begining of that), played properly and on beat.
