Ran, Rui and Midori get involved with Rin's classmate Reika when they find out her brother has gone missing. They investigate into it and go to the town where he was last seen. While there, they learn about the legend of Three Caches, a village inhabited by the Three Eyes Clan known for their savageness. Ran and Midori gain access into an old man's home to ask him about Reika's brother, but he does not give them information even though Reika's brother left behind a note with the man's name on it. That night, Reika is abducted by the old man's men in the middle of the night, and Ran is knocked unconscious via chloroform and taken away somewhere.
