Gaku Hoshikawa

"Gaku... FiveRed!"

Gaku Hoshikawa (星川 学) is FiveRed of the Fivemen.

Fiveman
He is the eldest and leader of the team. A Science teacher skilled in kendo, Gaku was 7 at the time of the Zone's attack on Sidon. Calm and responsible, he had the task of raising his four siblings along with Arthur G6, making him not just a big brother but also a leader and a parental figure.

Out of fear, fired a gun at Garoa's face, scarring him, creating a rivalry. Even though he is a reliable and brave leader, he has a major weakness with the supernatural.

Super Sentai World
Gaku later led his team in joining forces with the Jetmen, Zyurangers, Dairangers, and Kakurangers to defeat the evil Emperor Daidas and his forces.

Gaoranger vs. Super Sentai
Led by his Liveman predecessor Red Falcon, he appeared as one of 24 previous Red Rangers in Gaoranger vs. Super Sentai together with fellow Red Rangers from his predecessors AkaRanger to Red Turbo to his successors from Red Hawk to TimeRed.

Gokaiger
Years later, Gaku fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. Kaijou noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The FiveRed powers are later used by Captain Marvelous via the Ranger Keys.

After the defeat of Ackdos Gill, Captain Marvelous returned all the Ranger Keys to the former Sentai heroes. It is assumed Gaku received his key alongside his younger sister Remi, allowing for them to utilize their abilities once again.

Super Hero Taisen
Gaku, alongside his team, among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

Ranger Key
The FiveRed Ranger Key (ファイブレッドレンジャーキー) is Gaku Hoshikawa's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The FiveRed Ranger Key was mainly used by Captain Marvelous (Gokai Red), who used it to fight as FiveRed. It was also used by Don Dogoier on one occasion.
 * When the Gokaigers became the Fivemen while fighting a Zangyack force led by Insarn and Barizorg.
 * When the Gokaigers became the Fivemen while fighting Zangyack shortly before the team found out that Don was apparently a legendary hero.
 * Don became FiveRed as part of an all-red Gokai Change when the Gokaigers teamed up with the Go-Busters while fighting against Bacchus Gill.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Gaku received his key and became FiveRed once more.

Red Spirit
As the fourteenth Red, FiveRed's Red Warrior Spirit was embodied by AkaRed.
