Keiichi Akagi, a veteran war photographer for Horizont agency, mentors Saeko Shirasu. He first encountered her as a student drawn to his exhibition work, and five years later secured her assignment to document Uddiyana’s civil war, recognizing her potential.

Operating primarily in the capital during the conflict, Akagi maintains local contacts like informant Naraya. His independent pursuit of political conspiracies and UN activities contrasts Shirasu’s embedded reporting. He uncovers evidence of UN bombing campaigns and geopolitical manipulations, including hints of major powers testing experimental mecha under peacekeeping cover.

Their relationship evolves significantly in Uddiyana. During a chance meeting, Shirasu entrusts him with classified UN files containing evidence of the HAVWC prototype and other operations, instructing release only if she dies. Akagi later views this as a missed intervention opportunity, foreshadowing subsequent events.

After Shirasu’s death in a post-conflict terrorist attack, Akagi becomes the posthumous curator of her work. Reviewing her photographic archives, video footage from embedded missions, and personal webcam recordings, he pieces together her experiences with the SDC unit. This reveals his contemplative reflections on journalistic ethics, imagery’s power in shaping perception, and war’s hidden costs.

His pragmatic, duty-driven personality shows strong loyalty to principles and colleagues. Classified as ESFP (Myers-Briggs) and Enneagram Type 1w9, his traits of practicality, structural adherence, and desire to improve an imperfect world fuel persistent truth-seeking despite institutional obstruction.

In the aftermath, Akagi preserves Shirasu’s legacy by compiling her documentation of SDC operations and the conflict’s human impact. His final act as keeper of historical record ensures her perspective survives suppression attempts.
