Well, there are only boys here though.
The future surely won't be rewarded. Valves, steam, bats, the underground. Even in close-quarters combat met with restraint, voices were swallowed up. Surely there's no hope in the world. The elaborate ideals of adults. With a single, pure, honest fist, judge the lies, break the shell. Entangled night ride, brave youth, clinical bloodstains, linoleum. To you, this distorted city is reduced to mere cunning. There's no such thing as expectation. A desolate route, getting better only at making excuses. In a war of insensitive love, let's retaliate every day. How many times must I strike, bristling with bloodlust, asking "What is your justice?" Hey, Yankee Boy, Yankee Girl! Try howling until your voice goes hoarse. Even if you strike everything and forget, the wounds will remember instead. Hey, Yankee Boy, Yankee Girl! It'll reach you straight, won't it? A gang under the overpass, a spiral of graffiti, magnetic field lines on a broken utility pole. Corpses of spray cans in the ghost tunnel. Now, prepare for armed conflict. Roaring barbed wire, the quickening of threats, clashing sword guards, staring contests, Route 80. I was afraid of doing something irreversible. Body temperature that won't cool, inferiority that filled me deeply, that heart that will never return, withered and rotted. More than anything, I prayed for a tomorrow I wouldn't doubt. Value and pride, plugs and lights, before waking from the dream. Hey, Yankee Boy, Yankee Girl! Move forward like the blood flowing through you. Even the blueprint of a faded film, before becoming an adult. Hey, Yankee Boy, Yankee Girl! I want to try leaving something behind. Lying on the rooftop, I wiped away and hid my tears. Unable to be honest, yet remaining sincere. Your fist has already become stained. It won't reach anyone anymore. Not a fragment of purity, not a fragment of innocence. That kind of strength... Isn't justice! How many times must I strike, bristling with bloodlust, asking "What is your justice?" Hey, Yankee Boy, Yankee Girl! I want to laugh with someone. Tomorrow, and the day after too. No matter how many times I'm struck down, I want to see the morning sun. Hey, Yankee Boy, Yankee Girl! I'll carry it myself. I won't let your future be defiled!
