Ray is one of five students at NAZKA Academy, a boarding school plagued by mysterious blackouts and alien abductions. When Halle's sister reveals her blackout experience, Ray and his friends begin investigating. They uncover malicious alien activity, identifying an infiltration by Reptilians. Ray actively gathers evidence to prove the threat, including a crucial moon rock, though it is stolen before he can present it. Despite widespread skepticism, he persists in exposing the Reptilians. Ray participates in a mission using Professor Suguru Yoake's machine, leveraging the principle "like attracts like" to contact benevolent Unmite Aliens. This contact leads Ray and his friends on an off-world journey aboard a UFO, exploring planets and discovering cosmic secrets. Their return to Earth triggers a confrontation with the Messenger from the Flip-Side Universe, a trap critical to Earth's survival.

In the sequel, as a university student, Ray continues combating extraterrestrial threats alongside his original NAZKA group: Anna, Tyler, Halle, and Eisuke. They undertake a secret mission against invading space Reptilians. During this conflict, Ray travels back 330 million years in Earth's history to find his missing friend Tyler, trapped by the evil alien Dahar. This time travel coincides with the plans of Alpha, the God of the Earth, who is establishing a new civilization and has invited Queen Zamza's Reptilians from planet Zeta. Ray's journey places him at the center of events involving humankind's creation, interactions with alien species, and the revelation of the Earth God's existence. His actions contribute to uncovering humanity's reason for existence and the broader cosmic conflicts tied to Earth's future.
