Kichijouji Escalation Yard

The protagonist "Kou", who was born and raised in Kichijoji, unwillingly spends his days working in a woman's specialty underwear shop. One day, a chain of bizarre murders occur in the streets of Kichijoji. Every week, a new girl will be kidnapped and raped before being murdered, in an event that has become known as the "Moth of Wednesday"... Eventually, the incident also starts to involve the girls surrounding Kou. "Yeah, I'll protect you! I promise..." But in order to fulfill that promise and to regain peace in your hometown of Kichijoji, he must safely rescue the abducted girls by following the footsteps of the murderers by inspecting the murder scenes and tracking them down. A storm starts to brew as things heat up in the darkness of the Neo-Urban City of Kichijoji. If you win the "dart shooting" confrontation with the murderers you can safely rescue the heroine, which begins the love scene, but if defeated, the heroine is raped and murdered by the perpetrators and the game is over.
