Kishiryu Sentai Ryusoulger: Guardians of the Moon

This idea is a remake of Saint Seiya and Fist of the North Star. It is to also involve other series as well.

Plot
The series stars deliquent and Hokuto Shinken practitioner Seiya Takane and his misadventures with the Triads and some corrupt governors as well as dealing with an evil cult with aspirations of world domination. While the story begins with Seiya and his friends Shiryu Kenzaki, Hyoga Shinatora, and Shun Kawai, entering an illegal underground fighting tournament to win a prize of 500,000, that changes when Shun's brother Ikki Kawai appears with some Triads to assist him.

After defeating Ikki and the Triads, Seiya goes to his childhood friend, Kurumi's house when he learns from her ill mother that a Chinese gangster named Hakuron kidnapped her and took her to China. Desperate, Seiya gathers his friends and an reformed Ikki and heads to China to deal with her kidnapper and his lackeys. After defeating the gangster's lackeys, the heroes split up as they fight Hakuron's most trusted minions and Hakuron himself. After a long and hard-fought battle, the heroes finally defeat Hakuron and return to Japan with a broken Kurumi.

After a few months of peace, things turn bad once more when Shun's girlfriend gets kidnapped by some men in black.
