Kitase Kazuhiro is an ordinary salaryman who always leaves the office on time. Though this is Japan, so perhaps hes not really ordinary after all. Whats truly strange comes after that; Every night, he takes a shower, changes into his pyjamas and has a good nights sleep. Then he dreams of a fantasy world, and only wakes up when he dies or sleeps in that world. One day, hes killed after stumbling onto a dragons lair. "A nightmare", he sulks, until he finds his elf friend in his bed.
