The NIS Lunatic's Form is Insane

Introduction to the Work: A chaotic, spectacular, refreshing action fantasy. A Sword Master in another world, a jobless bum on Earth. A former Sword Master who has been unemployed for a year, fighting a job market more fierce than the Great Demon War. One night, after saving an NIS agent, he is recruited as a black ops agent. But this guy is something strange. Very, very strange. The slapstick spy adventures of a former Sword Master full of crazy energy.
