G

Giotto's childhood friend who later became known as Vongola Primo's right hand man. In the past, he always sided with Giotto's ideas and gave his greatest efforts to support his friends. G. once commented that, despite the fact Giotto gave him a lot of trouble by making him go along with his unreasonable acts, he never regretted following his friend. Around the time that he and Giotto started their team of vigilantes, they were often told "what can a bunch of brats possibly accomplish?".

The first man to take up the title of Storm Guardian of the Vongola Famiglia, G. was a skilled fighter in both ranged and close combat. During jobs, he usually made use of guns that he devotedly practice how to handle. But when acting on Vongola Primo's personal requests, he instead used a bow and arrows that he received from Vongola Primo himself and was never defeated. This strength got him renowned as "the hurricane that blows violently".
