Heres the synopsis:
A dull high school student, Hiro Yuuki, acquired the full-dive RPG "Kiwame Quest" by chance. The game, created with the best of technology, lives up to its catchphrase "Mastering Realism." The graphics, the behavior of NPCs, the scent of plants and trees, and the breeze that strokes your skin, everything is the ultimate in quality. --Except the fact it is too realistic to make it a troublesome game that it is impossible to clear! "More than 10,000,000,000,000,000 flags!? My physical abilities are the same as in the real world!!" "Yes. If you get hit, it hurts, and if you get cut, the wound doesn't heal for days. It's the most realistic game ever!" The only reward is a sense of accomplishment. Conquer the most stressful game of all time, which can't be played lightly!"
