Must Fight!!!

My beginning was so different Work hard over time, but the salary isn't sufficient Enjoy my own achievements Attack vicious zombies at this moment My will overcomes everything, with endless fulfillment Huh!!! Yah!!! Seems like... my students? No, no, no........ What have I done? Keep moving forward brutally That's where I hope to find sympathy The sunset light glimmered slowly But it cannot stop the power of the tribe within me A spacious wild place, planes bombarded the sky fiercely Help the last survivor quickly, and join them in fighting the evil zombie!
