History
Ultraseven
Takenaka is an advisor of TDF responsible for dispatching to the Eastern Base Branch to handle UG operations. When Captain Kiriyama is not present, he sometimes serves as the acting commander in charge of commanding the troops and infiltrates missions, analyzing the information obtained by the members of UG.
During the face of the biggest invasion in history, he comforted the troops who were dissatisfied with the surrender demands of Alien Ghose and thus showed a more calm attitude than others, calmly thinking about the survival of humanity and discussing strategies with the advisors.

Takenaka was still a staff member of TDF albeit as a director of the Far Eastern Base. During the destruction of the Moon Base by Alien Valkyrie, Takenaka appointed Kaji to succeed Furuhashi, who unfortunately was among the casualities of the rampage, in taking charge of the UG. Legends and Glory
Later on, when Kaji supposedly had them terminated following the amok of one of the Ultra Hawk machines, the team's captain, Sanshiro Shiragane, attempted to resign but Takenaka refused to accept it. Sooner, when TDF took Kazamori, one of the Ultra Guard members, in custody after they found him in the storage facility with unconscious guards and identified him as an alien, Takenaka and the rest of the TDF staff were convinced by Kaji that Ultraseven should no longer be trusted after revealing that he knew about the Omega Files.
They were initially in confusion. Later, when Kaji left to track down some Ultra Guard members and then Ultraseven, a monster which rose up from the ground began tracking down some TDF facilites, that included the transmitting satelites. That made them put into shock. Shiragane later arrived in the conference room to seek permission to open the Omega File and transmit it to the entire universe. After justifying his reasons about it, Takenaka finally agreed and allowed him to do so. He then ordered Kaji to ceasefire and let Ultraseven check the contents of the Oparts (an ancient casket which was excavated a day ago and was placed in the storage facility) himself. However, Kaji ignored his order and proceed a failed attempt to stop Seven. After the monster's defeat by Seven, Takenaka declared the Earth's entering the new age of peace, ultimately leading to the abolition of the "Friendship Plan" aggression plot. I Am an Earthling
