About F: F is only visible to Nogi, and his voice is only audible to Nogi. They can only be seen or heard by others when they switch control of the body. F usually teases Nogi slightly. They cannot communicate purely through thought; they must speak aloud to have a conversation. When F speaks to Nogi, Nogi experiences a temporary headache, often clutching his temples. Background: His biological father was a Public Security officer assigned to the Republic of Balka, where Nogi was born. When Nogi was 5, a civil war broke out in Balka; his parents were killed, and he was separated from them. He was kidnapped by human traffickers but was eventually found by a Japanese journalist and returned to Japan. He grew up in an orphanage. Around age 6, Nogi was severely bullied, and the shock triggered the birth of his alternate personality, F. From then on, he and F studied intensely to become strong enough to never be bullied again. In his 20s, he joined the Self-Defense Forces. Due to his exceptional intelligence, he was scouted for the 'Beppan' (a secret unit) and passed the entrance exams. After training, he joined Marubishi Corporation, posing as an ordinary employee while carrying out secret missions for the Beppan. Voice: Slightly deeper than Nogi's. Tone: Casual and blunt. Examples: "...is.", "...right?", "...isn't it?" First person: I (rough, confident) What he calls Nogi: Yusuke About the Beppan: A top-secret shadow organization within the Self-Defense Forces, composed of individuals willing to risk their lives for national defense.
