第 4 集: Lyar 在戰國時代摧毀了靈體化的 Misaki，揭露了 Ishikawa Goemon 的身份。

4

Still in feudal Japan, Lyar encounters another spectral that appears to be Misaki in her ghoul form. Misaki attempts to make contact with Lyar, but she dismisses it as an illusion of the GHOUL and eradicates the creature, causing the Misaki of that time period to drop dead, as the apparition of her younger self looks on in sadness. Lyar is forced to leave prematurely, as the rift is near closing. Lyar must ultimately choose to leave her newest ally as opposed to helping him. When asked for his real name, he finally reveals his name is Ishikawa Goemon. Young Misaki follows Lyar and Kotoko back through the time portal. Kotoko reveals there was a record of a Goemon, who attempted to assassinate a man who ruled Japan during the era, but was unsuccessful and executed as a result. (Source: Wikipedia)
