Elina Line: After leaving the laboratory
Elina once lived at the Russian Institute, and after Sayo destroyed the facility, she came to the sea city. Later, the Russian side targeted Yuto for military purposes, causing the two to be chased in the latter half of the storyline.
Miu Route (2012 Main Story)
Elina, Yuto, and Miu work together to destroy a radio jamming device.
Elina Route (2012 Main Story)
Naota becomes a hostage of Takano during the drug L investigation. Elina told Yuto to close his eyes, then drained his blood and subdued the scene with her electrical power; Takano and Naota were both shocked.
Yuto accompanied Erina to the hospital, and Motoki decided to get checked first. Later, their blood-sucking activities within the academy sparked rumors, and both were disciplined with caution.
To resolve Erina's condition, Sayo contacted the Russian Research Institute, which then sent people to the island. During this time, Yuto was assigned to keep an eye on her surroundings.
Erina and Yuto subdue the police squad in a busy downtown area, then cooperate with Sayo's disguised shooting, and together they fall into the sea, boarding a standby ship to leave the island. Half a year later, the two returned to Aqua Eden to reunite with friends.
