Drug investigator Yakushima spasm

Yukawa Himekawa, a government investigator, is devoted to the enemy Agito to save colleagues who are caught in a certain drug organization. It is caught up with the boss of the organization in the regrettable place though it is YUI who aids the co-worker by the last thought, and the medicine being produced in the organization is taken. The effects of the drug were so great that the whole body would not be able to bend to the irritating stimulus and to endure many men.
