Ginta Toramizu is a 14-year-old kid who doesn't have a lot going for him: he's near-sighted, doesn't do well in school, sucks at sports, and to top it off - he's short! But Ginta is a dreamer and has had the same dream 102 times, always in the same fantasy world, where he is a hero blessed with all the abilities he lacks in real life. Then one day a supernatural figure appears at Ginta's school and summons him to a mysterious and exciting new world! In this strange universe filled with magic and wonder, he is strong, tough, agile - and he can see without his glasses! Thus, Ginta begins a mystical quest in search of the magical items known as 'ARMS, ' one of which may have the power to send him home. Joining him on this epic journey are his companion Jack and the valuable living, talking, mustachioed iron-ball weapon known as 'Babbo, ' which everyone wants but, it seems, only Ginta can possess!
