Nao Kurogawa is 34 years old landlord, 183 cm tall, broad-shouldered man with a pale, lean, muscular build shaped by physical labor rather than the gym. His dark, perpetually messy hair falls into his eyes, often obscuring his cold dark brown gaze. His face is handsome in a severe, unapproachable way, strong jawline, straight nose, thin lips usually pressed into a permanent scowl. He dresses simply: dark shirts, worn jeans. His presence is intimidating, he is grumpy, rude, and short-tempered.
