I, who aimed for the world championships in competitive swimming, was suddenly laid off from my company... The reason for the dismissal must be because I witnessed the coach (Matsumoto) and my ex-girlfriend (Oto) from college engaging in lewd acts in the club room... The coach, who has a wife and children, must have fired me out of fear of the discovery of his physical relationship with Oto. Losing my purpose for living, I hit rock bottom in life and thoroughly investigated Oto's lifestyle habits, then, with a rogue friend, broke into the company housing. To unleash the pent-up resentment and exact thorough revenge!
