A childhood friend of the Lowain bros, he has always fit in seamlessly with the others despite being three years older at twenty-five. He takes pride in being the older brother figure and is known as the best brawler around, often stepping in to protect his friends when they (mainly Tomoi) get into trouble. Despite his strength, Big G has a somewhat fragile mentality and is the most prone to loneliness in the group. Although he tries to hide it, everyone knows he cried into his pillow the night he learned that Lowain and the bros were leaving the island.
