Retsuko trudges through life just like the rest of us. She has a crappy boss, annoying coworkers, and has to stay late way too often. But there's one thing that can relieve all that built up pressure. And that's death metal karaoke. Retsuko screams out her frustrations over pig bosses and doe-eyed suck up in an 8 by 8 karaoke room. She's not just Retsuko, she's Aggressive Retsuko. Aggretsuko.
