A childhood friend of the Lowain bros, he shares a close bond with them, having known them the longest. Cheerful and kind, he is also serious and responsible, often looking out for his friends with his keen observation skills. However, he tends to neglect his own well-being, enduring work conditions far beyond his limits. By drinking Handsome Gorilla Triple Attack on a senior colleague's recommendation, he managed 24-hour workdays but developed an unusual cough, which has vanished since he stopped using the product and started focusing on his health. His latest worry is that his son has started calling him "chief" after he proposed a family trip to Auguste using his accumulated vacation days.
