Masterpiece / Shishi Shishi MV

It’s a blistering rock number.

This track is a tie-in with the basketball manga “Ichikabachika,” and since Shishi Shiji is a fan of the series, it was created through a reverse offer.

The resolve and fighting spirit of the characters who face adversity by trusting in their own weapons are expressed through clever wordplay.

The rushing sound and catchy, powerful melody make your chest swell with excitement as you listen.

It’s a motivational song we hope people who are passionately devoted to something—or those who want to psyche themselves up before a big moment—will listen to.
