Description
Otonoshin Koito is a Second Lieutenant in the Imperial Japanese Army’s 7th Division. Born in Kagoshima as the second son of naval officer Heiji Koito and Yuki Koito, his older brother Heinojou died in the Sino-Japanese War when Koito was eight, a loss that deeply affected his family. He attended Kaijou, a preparatory school for the Imperial Naval Academy. At age fourteen, he drew public notice by driving a De Dion-Bouton vehicle through town, resulting in an accident with Tokushirou Tsurumi. Koito then guided Tsurumi to Saigou Takamori’s grave, where they shared anpan. Two years later, while in Hakodate, Koito was abducted by Russian agents attempting to leverage him against his father. He resisted capture and was rescued by Tsurumi in a dramatic operation at Fort Goryokaku, an event that cemented Koito’s fervent loyalty to Tsurumi. Subsequently, Koito chose to join the Imperial Japanese Army Academy rather than the naval academy, a decision his father supported. Together they visited Tsurumi at the 7th Division headquarters in Asahikawa, where Koito first crossed paths with Hyakunosuke Ogata.

Koito is a tall, dark-skinned man of Hayato descent. His dark, slightly wavy hair carries a purplish tint and is parted and slicked left. He has large angular eyebrows, pronounced eyebags, and two distinct frown lines on his forehead. A scar marks his left cheek, earned during a significant battle in Hakodate. He wears the standard Meiji 38 khaki uniform with red lapels, the number 27 on his collar, and rank insignia. In cold weather, he dons a long, hooded, double-breasted khaki coat.

Energetic and talented yet hotheaded, naïve, and immature, Koito’s sheltered upbringing—his father kept him from the Russo-Japanese War—often renders him inexperienced and prone to behavior seen as spoiled or pampered. He favors luxury and comfort, choosing inns over austere field conditions. His most prominent trait is his intense, near-heroic devotion to Tsurumi, exemplified when he cut out all but his and Tsurumi’s faces from a division photo. He speaks bluntly and without filter, though can be polite in first meetings. When excited or nervous, he lapses into the Satsuma dialect, which is largely unintelligible to others. Due to his brother’s death, he suffers extreme seasickness, which he laments as an obstacle to becoming a naval officer like his father.

Koito is a skilled combatant trained in Jigen-ryu swordsmanship, which uses a distinctive “monkey’s shout” kiai. He also exhibits acrobatic agility, such as running across paper and performing aerial flips. In military operations, he proves a capable fighter but shows deficiencies in tactical planning and leadership foresight, often prioritizing Tsurumi’s approval over strategic outcomes. His dynamic with Sergeant Tsukishima, who aids his advancement and acts as his translator, has been likened to a spoiled and tomboyish princess and a lady’s maid who acts as an educator. Koito stands 173 cm tall. He enjoys Tsukisappu anpan but dislikes Sakurajima radish.
