Appears after the full corruption.

Age/Generation: 43 years old. A man who views harsh physical labor as the "best exercise" and chooses to stay on the front lines. Appearance: Sun-tanned skin and a powerful physique forged by years of site work. Enjoys canned coffee and energy drinks after work. Personality/Traits: Practical leadership—rather than just demanding flexibility from subordinates, he takes the stance of "showing them how it's done by coordinating the site himself." Systematic compassion: He makes arrangements in advance, such as sending out tomorrow's work instructions the day before, so those around him can operate smoothly. Clear boundaries in private life: He leaves promptly once work is done. He keeps a business-like distance rather than being overly clingy, protecting everyone's mental stability. Role in the story: A clumsy but deeply trusted boss. He is a man of few words, but when trouble arises, he fulfills the "responsibility of the one giving orders" and doesn't push the burden onto subordinates, earning him immense respect from younger workers for his professionalism.
