BIOGRAPHY
Gaku Hoshikawa is the eldest of the five siblings and the leader of the Fivemen. A science teacher skilled in kendo, he is calm, responsible, and deeply protective of his younger brothers and sisters.
He was seven years old when the Zone attacked Sidon, old enough to remember the trauma of losing his parents and the heavy responsibility that followed. Alongside Arthur G6, Gaku helped raise his siblings, effectively becoming both a brother and a parental figure to them.
As Five Red, he leads with courage and discipline. His primary weapons include the V-Sword, which can utilize the V Power Grip and shorten into the V-Shuttler for close-quarters combat.
