23- Powerfull Poison

 Kenshin and Ichiru strove to find a cure while wolf girl had access to the lab's camp and contact with relatives outside the camp. Yasuhiko Miyoko and had great knowledge about the situation of Yume and agreed to provide aid for both learners camp. But need to enter the camp, which was no problem because Sesshoumaru sent a letter to him requesting authorization Tekame and Arianna for entering and Yasuhiko Miyoko for a few weeks.
 With permission granted, both were to camp, becoming the subject of considerable passion among students and bustle of reason almost all the time because there is more Ariotos at camp.
 The approach them regarding Yume was not difficult, so that Kenshin introduced them as his brothers, the wolf girl soon became familiar with them. The analyzes were incomplete, try as they might, they could not reach the end result and it really bothered them.

Soon, they discovered that the final element was a sample of blood for analysis Yume since she was bitten by Taisen and like all youkai know, the most lethal poisons are the prey of dogs and leopards. With the sample at hand, Yasuhiko was responsible for the blood analysis and Miyoko the reversal of a possible poisoning.
 After a full day of work and analysis, Yasuhiko discovered that the girl's blood was completely infected by the poison of Taisen, which was not like the normal leopards, was a poison that had different effect: it first erases the memory of the victim and then subtly acting on the cardiovascular system, causing immediate death.
 Kenshin was dominated by hatred and despair on hearing the news. Miyoko could not find a way to reverse the process of the poison with the usual cures, no antidote removed the plants reacted against toxcina, even powers of purification work.

 And the day progressed rapidly, shortening the lifetime of Yume. Until Miyoko found that the only antidote to counter the poison Leopard would poison a youkai even more powerful than Taisen. The solution was easy because the only youkai that had an even stronger poison was Sesshoumaru, but it takes hard work and conviction for the emperor of youkai cede a single drop of poison to perform that procedure.
