Katou Keiko (加東圭子 ?) is a Witch from Fuso and attached with the Fuso Imperial Army. During her period in the 1st Fighter Squadron, she received the nickname "Higashi" (ヒガシ), based on an alternative reading of the second character of her family name. Back then, Katou Takeko was part of the same team, so Keiko was called like this to disguise the fact that there were two "Katou". When together with Takeko, the two are collectively called "Fujitou" (藤東). While on Europe and Africa, she was called by the pet name of "Kei" (ケイ).

Actually, both her hair and eyes are black, but they kind of look like a light brown with a pale pigmentation. Her hair is quite soft and lost some of its coloring due to long exposure to the desert.

Her favorite camera is a Leica II. Incidentally, this was originally Takeko's hobby and Keiko learned how to use a camera from her.

Her archetype is likely Katou Shouji (1912-1941) from the Imperial Japanese Army Air Service.


Because her powers as a Witch manifested themselves since before the invasion of the Kaii, Keiko volunteered for the army and matriculated into a military academy. Upon graduation, she was appointed as a Pilot Officer and assigned to the Army's 1st Fighter Squadron, under the command of Wing Commander Etou Toshiko.

In this squad, where exceedingly excellent Witches were sent to, she participated of the Fuso Sea Incident and displayed a performance that turned her into the top ace of the Fuso Army. Because of these services, she and her coworkers Katou Takeko and Anabuki Tomoko were called the "Fuso Sea Triumvirate". It seems that, around that same time, she interacted with the Navy's flying corps and became friends with the famous Sakamoto Mio, who would later turn into one of the "Libau Triumvirate" and 501st Joint Fighter Wing's combat commander. She was also an acquaintance of Kuroe Ayaka.

An ace of the Fuso Sea Incident who shot down 23 units, of which the first six were consecutive. This score makes her the top ace of that incident. The reason why she was not made the protagonist of "Flash of the Fuso Sea", despite being the top ace, was because someone decided that her combat-style - which specializes in mid-range preemptive fire - would not look good on the screen.

At the victory ceremony after the Fuso Sea Incident, Keiko attempted a dangerous aerobatics, crashed and received a serious injury. It was to the point that her life was in danger for a moment, but she was saved thanks to the earnest treatment of the medical team and Witches. In this period, the notes about the Fuso Sea Incident - titled "It came, it flew, it crashed" - became a valuable book that described in detail the battle conditions of that time.

Upon reaching her 20s while hospitalized, she realized that participating in battles from then on would be difficult and retired. Keiko became a war correspondent afterwards and assertively collected data on many Witches around Europe, leaving behind many photos and articles. She would also collected data on Squadron Leader Rall, who would become the commanding officer of the 502nd Joint Fighter Wing.

However, an interview with (at the time) Flying Officer Marseille would rekindle Keiko's desire to fly, led to her apply to the Fuso Army for re-instatement. Although her intention was only to serve as flight instructor back in Fuso, the Army Command instead ordered her to await for assignment in North Africa - as it turns out, she was not only re-commissioned with the rank of captain, but also being assigned as the CO for the Fuso's African Expeditionary Force Independent Flight Squadron. Commonly known as the "Sand Corps", it composed of a flight company (with just one witch, two if including Keiko) and a maintenance company. A FUBAR on the orders and instructions given to Keiko forced her to improvise, thus she opted to camp out with the JG27 (only the JG27 operates an active airfield with established logistical train) at least for the time being to get organised. But as fate would have it, that indirectly resulted in Marseille "suggested" the formation of a joint unit, thus the 31st Joint Fighter Squadron Afrika was born, with Keiko as the squadron's CO.

In chapter 7 of Kimi to Tsunagaru Sora, Kuroe Ayaka mentions that Keiko, like Anabuki Tomoko, is bad at keeping in regular contact with her compatriots back in Fuso.

As much as serving in the capacity of squadron CO and principal instructor for Mami, Keiko also continue her war coorespondent job on the sides, reporting the activities of the 31st JFS Afrika for the press; and her advantage of proximity to Marseille led Keiko became the de facto exclusive photographer for Marseille, whose celebrity status made her photographs well sought-after items.


Keiko's inherent magic is called Super Eyesight (超視力, chou shiryoku), which not only improves her dynamic vision but also allows her to look into the distance, much like Sakamoto Mio's Magic Eye. With this ability, she is capable of shooting down even a flying bullet.

Her magic power has degraded with her age, to the point that she can no longer raise a magic shield. However, she can still operate and fly with a Striker Unit. Thus, her roles during combat are airborne command and photo reconnaissance.


Keiko's Ki-61 is equipped with a Ma-40 engine, which was license-produced from the Karlsland's DB-601.

Throughout her career, Keiko has employed a wide array of weaponry, which included a Type 38 rifle, a Type 97 anti-tank rifle, a Type 98 flexible-mounted machine-gun (which was license produced from Karlsland's MG-15), a Type 1 machine-gun and an Ostmark-made ZB-26 light machine-gun. She aslo keeps a Beretta M1934 as a personal sidearm.
