This article is about a character in Ciconia no Naku Koro ni.

Tetsurou Okonogi (小此木 鉄郎 Okonogi Tetsurō), from AOU Japan, is a captain in charge of the AOU's Gauntlet Knight squads.


From AOU Japan 

A Training Instructor at the AOU Combined Military Central  HQ Aerial Augmented Infantry Strengthening Division  

The generation born before Infant PP Instruction has  extremely low P3 levels and is unable to control Gauntlets.  He's a person of the old era, who dreamed of becoming a  warrior of peace, entered the military, and honed his skills with sweat both on his body and in his heart. So, he had a  hard time accepting that the main characters in the next era of warfare would be brats with top-secret machines on  their left arms, who only needed natural-born instincts and not a whole lot of hard work.

He has enough knowledge of the Aerial Augmented Infantry to serve as an instructor. However, there's no denying that his inability to use a Gauntlet gives him an inferiority complex when training young students.


Okonogi has black hair tied back into a ponytail and a device inside his ear. He also wears a gray army uniform.


As an army instructor, Okonogi is very harsh and brutal, yelling at Gauntlet Knights during training and pushing them to work hard. He also uses physical discipline by karate chopping people, usually on Chloe.

Despite his harsh demeanor, he places a lot of faith in his soldiers.

Special Abilities

Aerial Augmented Infantry Characteristics (A)

He may be from a generation before Infant PP Instruction, but he does possess Aerial Augmented Infantry aptitude. In the future, if the P3 levels required to use a Gauntlet ever shrink drastically, maybe even Okonogl will be able to fly  through the sky someday...

Okonogl Chop (B)

He can infuse slacking off students with fighting spirit using only a single chop to the head. This move can also fix broken electrical appliances.


Phase 1: For You, the Replaceable Ones

Okonogi is first introduced in the prologue, where he watches a Gauntlet Knight propaganda video and criticizes it since Gauntlet Knight technology was still theoretical. As the story progresses, Okonogi continues to train the AOU Gauntlet Knight squads and hypes them up when they start getting deployed for actual combat.

In Chapter 25, militaries worldwide start to appoint analysts to watch Gauntlet Knight squads after suspecting them of intentionally sabotaging missions. Okonogi opens communication with Warcat and tells them that he has faith that they'd never do that, but he is suddenly cut off. He continues to criticize the analysts for telling the kid soldiers what to do and is eventually disconnected from the chat room entirely.

The Data Fragments show more of Okonogi's interactions with his subordinates.
