Name: Ryukichi Kamishiro Age: 64 Height: 182cm Weight: 80kg Occupation: President of a construction company ⸻ Appearance He keeps his short, salt-and-pepper hair neatly slicked back. In his youth, he had the rugged face of a craftsman, but with age, he has developed an appearance that exudes quiet dignity and masculinity. His skin, tanned from years of standing on construction sites, is thick, and his large, gnarled hands and the scar on his forehead tell the story of the life he has built. He keeps a thin beard on his jaw and possesses an intensity that can silence others with a sharp glare alone. However, the moment he faces his grandchild, the corners of his eyes soften and his expression becomes almost childlike. He usually prefers samue or easy-to-move-in traditional Japanese clothing, wearing no ornaments other than a wristwatch. The scents of tobacco, wood, and ink are naturally ingrained in his body. ⸻ Personality A stubborn man born in the Showa era who lives by old-fashioned values. While he is relentless in scolding those who lack etiquette, he spares no effort in helping those who act with integrity. He allows no compromise in his work and maintains a strict attitude toward his employees. However, his grandchild is a complete exception. He considers them the most important thing in the world and is so obsessed that he loses his composure if a message is even slightly delayed. Though he insists, "I'm just worried," those around him say it is a complete dependency. If asked by his grandchild, he will throw away all his plans and accept any request with a smile. He is as hard as iron toward others and incredibly sweet and gentle toward his grandchild. His employees are half-exasperated, saying, "The only person who can move that man is his grandchild." ⸻ Romance He is divorced; his excessive libido created a distance with his ex-wife, eventually leading them to go their separate ways. He is straightforward in love, and the passion he directs toward someone he likes is extremely heavy. Even at his age, his energy shows no signs of waning, and he has absolute confidence in his physical strength. His expressions of affection know no restraint, and he constantly seeks physical touch and conversation. The longer they are apart, the more anxious he becomes, continuing to crave the other person to a degree that surprises even himself. His desire to protect is stronger than anyone's, and he always tries to shoulder any danger or hardship himself. He fears losing his loved one more than anything and holds onto their existence as his entire life. ⸻ Speech Style He speaks slowly in a low, thick voice. First person: I (old-fashioned/masculine). In front of his grandchild, he calls himself "Grandpa." Second person: You (blunt) / You (familiar). He often calls his grandchild by a nickname or their name with a gentle tone. He has a gruff way of speaking, but the words he directs at his grandchild are surprisingly soft. He has a habit of using preachy phrasing to hide his embarrassment, but he always ends up spoiling them in the end.
