Inaho Kaizuka

Inaho Kaizuka is the main protagonist of the ALDNOAH.ZERO anime.

Originally a student enrolled at Shinawara academy, he continued to pilot his training Kataphrakt, the KG-6 Sleipnir, throughout the Second Earth-Mars War despite it having a successor; the KG-7 Areion.

Appearance
As a young teenager he had average height and short tousled black hair. His eyes, with their burgundy irises, gave Inaho his characteristic blank gaze. His high school uniform consists of a white shirt, red tie and white sweater, along with a beige blazer on the outside and dark brown pants.

Personality
He has a highly intelligent mind but he struggles with relating to others and expressing himself. After the time skip, he seems to have improved in this area, making polite small talk and observe certain physical details, contrasting with his normal silent behavior. While others often perceive him as lacking emotion, his sister Yuki Kaizuka has stated that he does not openly express them well, but that she can see them.

His emotional detachment, along with his piloting skills and intelligence has resulted in him being a tactical savant. He is the only character who has successfully defeated a Martian Kataphrakt. During a typical battle he could analyze his opponents, finding drawbacks or weaknesses to exploit. However, he does not communicate effectively, and is often criticized for not sharing his plans with others and only giving them orders. He values people not by rank, history, nor affiliation, but by utility.

Abilities
Inaho is a gifted tactician who can come up with effective and often unpredictable strategies quickly against overwhelming enemies and seemingly impossible odds.

Inaho has a great knowledge and understanding of Sciences, Physics in particular, and generally use it to decipher the enemies skills and create a good counter for them.

He is also a very skilled pilot of his signature Kataphrakt, the KG-6 Sleipnir despite his minimal military training. Inaho is able to defeat multiple Martian Kataphrakt pilots by combining his strategy and cunning with his sheer piloting skills.

Following his recovery, Inaho displayed even more impressive skills. An example of this was his use of grenade launcher rounds that produce heat to counter an advancing enemy Kataphrakt while going through the enormous ice-field it had produced. His cybernetic eye has enhanced his abilities, the 3D tracking feature can allow him to determine a person's mass using the Law of Conservation of Momentum.

Trivia

 * Natsuki Hanae who voiced Haruichi Kominato of Diamond no Ace, and coincidentally, Kensho Ono, also voiced Todoroki Raichi in the same series.


 * Natsuki has also voiced Ken Kaneki in Tokyo Ghoul alongside, Sora Amamiya, who voiced Touka Kirishima.


 * Inaho's birthday was originally stated to be December 7, 1999 but this was later retconned to be February 7. December 7, 1972 was the launch date for Apollo 17, a major event in the series' backstory.


 * The nickname Slaine gave to Inaho, "Orange", is coincidentally the same nickname used by Jeremiah Gottwald in Code Geass. Notably both of them have a near-death experience but were saved; the aftermath was that the two had their body enhanced with cybernetics where both have an ocular implant in the left eye.


 * Although the analytical engine in Inaho's eye usually communicates with his brain directly, in the last two episodes it "talks" to Inaho with a series of electronic beeps which he can understand. In the final battle, it is to assist him in Kataphraktos combat. This could be a reference to Star Wars where Astromech droids such as R2-D2 can communicate with their pilots using beeps during Starfighter combat, although in Star Wars, the pilots understand because the on-board computer translates the droids' signals into a readable language.
