Others

Kō Yonamine (ヨナミネ・コウ, Yonamine Kō?)

Voiced by: Taiten Kusunoki (Japanese), Eric Vale (English)

A reporter working with Yuuri Kitajima, often gathering information for her. He seems to have had a past relationship with Yuuri, who is often annoyed with his advances. Kō also appears to be gathering information for Raina. He later helps Jin, claiming that it is for the sake of someone very dear to him. It is later revealed that he is working for an unknown agency.
In the official Dragonaut site, a whole section is dedicated to his reports of each episode's story (which are written in his point of view; revealing some information not shown in the episodes).
Widow (ウィドー, Widō?)

Voiced by: Saeko Chiba (Japanese), Jamie Marchi (English)

A woman who meets Kazuki after he gets beat up by a group of thugs. She is revealed to be a Communicator, and allows Kazuki to pilot her in order for him to retrieve Gio. She seems to have lost someone very dear to her, thus she partners with Kazuki because she feels that he has also lost someone who was very important to him. Though Kazuki treats her coldly, her only desire is to see to Kazuki's happiness. After the one-year time skip, she disappears once she reveals herself to be dying.
Like a spider, Widow can shoot fiber strands from her fingertips which can either ensnare targets or cut objects to pieces. She also has the ability to put someone to sleep with her nails.
Ostrum (オストルム, Osutorumu?)

Voiced by: Masami Iwasaki (Japanese), Justin Cook (English)

The fourth original dragon sent to Earth from Thanatos. His introduction is a violent one, as he destroys the ISDA's L-3 space station in his first few moments in Earth's orbit. He has no mercy for humans, but his top priority seems to be the destruction of the Earth-made dragons. He is able to take Communicator form, but who exactly he resonated with is unknown. However, the only known direct human contact he had before taking his Communicator form was with Yuuya. Later, it appears that Ostrum dies in an explosion caused by the Type-X warhead. However, he is revealed to have lived in the final episode, but then dies after he is defeated by Gio.
Ostrum is a fire type dragon. He is able to create bursts of flames, and is also able to incapacitate his opponents with blinding lights. As an original dragon, he is an extremely formidable opponent, and is capable of overpowering the entire Lindworm Unit.
Thanatos is shown to be able to produce billions of dragons resembling Ostrum.
