These Are the Days Episode 5

Oji Tanaka, formerly the lead guitarist of the '80s metal band Black Heaven, is walking on air. He's playing his guitar again, he's pulled out his old hip duds, and his Muse has returned - he's composing a new ballad. He bugs Layla about a chance to try his new song, and, based on his confidence, the aliens enter a key battle counting on increased power from his sound. Unfortunately, Oji's new mellow sound is utterly ineffective in powering the weapon, and it is only when Fomalhaut arrives to pull the plug that Oji finally twigs to the fact that he's participating in a galactic war - and that Earth will fall into jeopardy if they fail. Even worse, he learns that no one cares about his music beyond its ability to wreak destruction. His delusions and dreams shattered, Oji smashes his guitar and walks.
