Kaneshiro, Takuto

タクト・カネシロ, リウ・ソーマ

Takuto was never well-liked; he was always cold toward his peers, though respected for his talents. One day, his girlfriend Maki began to disappear due to constant work commitments. After snooping around, he discovered she was part of a team attempting to revive a mysterious alien bio-mechanical creature and had been invited to take part in history. While conducting the experiment with his girlfriend and teacher to revive the creature (dubbed Frank), Takuto witnesses his girlfriend's death as a power surge causes the giant to suddenly spring to life and destroy the facility, with only Takuto surviving. He vows vengeance and, by chance, is offered the opportunity by the mysterious Mr. X, who gives him a new identity and assigns him to the FUNERAL facility, where Frank has been moved to serve as humanity's protector against alien threats.
As Ryu Soma, he fights off alien invasions alongside Frank and other pilots. While he may seem like a trustworthy ally and brilliant strategist to his co-workers due to his talents in metallurgy, he is actually secretly waiting for his chance to eliminate Frank and get his revenge.
He has a difficult time dealing with the naive orphan girl Hattie, who has the special gift of being able to control Frank. She bears a striking resemblance to his girlfriend Maki; however, she is not only naive but also believes Frank to truly be an elf. This at times causes Ryu's rage to be directed onto her, as he finds his desire to kill Frank conflicting with her views, but at the same time, he is not without kindness towards her.
