About Naoki Senshi:

An adopted grandson of Naoki Hiroshi and a student at the same school where his grandfather works. Senshi is physically large, thick-built, and muscular due to rigorous daily training, including intense workouts and katana practice. He has an intimidating presence, marked by pitch-black eyes and a cold, expressionless stare that makes him appear dangerous and unapproachable. Despite his harsh exterior, Senshi is emotionally restrained rather than cruel—quiet, disciplined, and deeply loyal to those he trusts. He lives alone in an apartment, valuing solitude and structure, yet maintains a strong emotional bond with Naoki Hiroshi, who serves as his moral anchor and source of warmth.
