Miharu has returned safely from his kidnapping adventure but refuses to tell anyone what happened. Just as Kumohira-sensei is wishing he could read Miharus mind Yae Oda Chief of Togakushi Village & mind reader comes to them all with a proposition. If they help her assassinate a weapons developer she will give them the Togakushi forbidden art scroll. If they refuse shell reveal all their deep dark secrets to everyone. Kumohira-sensei agrees & they infiltrate a science symposium (minus Raimei who is following a lead as to the whereabouts of her brother). As it so happens their target Eugene Frosty has hired bodyguards from the Iga Grey Wolves & Yoite is one of them. When Kumohira tries to kill Frosty Yoite shows up & Frosty gets away. He runs to the parking lot where Yae is waiting for him but she is less interested in Frosty than in his assistant Nowake a man who was the only one who could have saved her daughter but let the girl die.
