Katō Kiyomasa
Kida Magobee himself was a real figure. He appeared as a retainer of Katō Kiyomasa in some contemporary sources. The "Kiyomasa-ki", a not-so-faithful biography of Katō Kiyomasa written in the mid-17th century, claimed that Kida Magobee was killed in a battle with the Jurchens ("Orankai") on the Manchurian border (in 1592). Japanologist Choi Gwan dismissed this claim. His name can be found in a letter written by Katō Kiyomasa about two months after his supposed death. One of the recipients was Kida Magobee himself. Until the end of the Edo period, the Kida family served to the Hosokawa clan, who replaced the Katō clan as the ruler of Kumamoto.
