Specter turns out to be Makoto, Takeru's childhood friend that had gone missing 10 years ago. What "hell" is Makoto talking about? What was his father researching? Takeru cannot hide his uneasiness as Sennin, as usual, doesn’t provide any answers. Reports surface about strange events ocurring in the laboratory of Professor Igarashi, an authority in physics who also went missing 10 years ago. Igarashi was an acquaintance of Ryu, Takeru's father. There may be some information about Makoto... Among the things, he finds a photograph of them with Saionji. A new character appears before Alain and Saionji takes the next step in his plan.
