For the main page regarding this character, see: Tetsuya Ida.

Tetsuya Ida is the substitute teacher assigned to Ryoko Shinonome's class at Sakura High School. He's actually a member of an unofficial organization who forces Shinonome into battle.


Ida is the director of the Special Investigations Unit (government affiliated spies).


He serves as an advisor to an anti-kaiju defense team, and helps Morimura gather members for their team.


Back when he was a student, he supported Tomi Kisaragi on her singing livestreams under the screename "F8".[1] He used to wear glasses, and came off as a studious, serious young man, but he tried to act cooler in high school to catch Kisaragi's attention.[2]


He was in love with the deceased Kisaragi, so in order to revive her, he developed androids at Shikishima Industries in 2100. He transplanted the past Kisaragi and Tamao Kurabe's AI into androids.


It was believed that Ida died when he stayed behind during the 2064 kaiju invasion. However, he was actually still alive, and took Shinonome into custody when she was being interrogated in 1984.[3]


Ida seeks to transplant the simulated personality of the revived Kisaragi android into the physical body of the current Kisaragi, but she rejects the idea. He then realizes he should've transplanted Kisaragi into the living body of the current Kisaragi to begin with, instead of reviving her as an android first.[4] For that reason, he aims to reset the world and begin anew.


Ida is genetically identical to Shu Amiguchi.


He saved his consciousness into Sector 0 to prepare for the next loop.

Notes

  1. Note: This screen name is actually "FE8" in Japanese, which makes its true meaning more clear. It's another way of writing "Tetsuya" in Japanese, and is fully explained on his page.
