Yasu (Show by rock!!)

Yasu is a boy with a somewhat serious and reserved personality, but with a determination to succeed.
He usually plays for the band Dokonjofinger along with his other bandmates (Hachin, Joe and Sojun), although they often end up fighting over stupid things, Yasu respects them.

Yasu comes from Dokonjo North High School, a high school that was left in ruins after a huge fight he had with his friends that ended up destroying it. To repair the damage, he and the others had to form the band as a kind of community service.

Although Yasu is somewhat serious and reserved, he also has a determination that drives him and the band to succeed.
He often sings and plays with intensity, passion, and determination.

She loves bento boxes; in fact, she lives with her mother in a restaurant that sells them.
And he hates being bothered, just like he hates the dark monsters who want to destroy music.

His guitar is called "Yata Iron Blue Ceremonial Crow" or simply shortened to "Iron Blue"
