The first half has a mysterious vibe, but in the latter half it modulates into a cool, hard-hitting rock feel.

The lyrics—about standing up to anything no matter how hurt or defeated you get—are perfect for those gloomy, overcast days.

The overall mood starts out cloudy or rainy, but it feels like the sun breaks through in the chorus.

This is a solo single by Inaba from B’z.

It has a different vibe from his work with B’z—another kind of cool track.

Inaba’s songs are tough to sing, but precisely because they’re difficult, if a man can sing them well, it scores high points.

The chorus is also easy to listen to.
