This series is the second in Toho's Seishin (Star God) series. The show aired 51 episodes between October 2, 2004 and September 24, 2005.

The series revolves around three humans named Shouta Date, Yuka Sanada and Shinya Hiraga who, one day, find themselves as the new heroes of Earth. Long ago, an alien from the Azure Planet named Nolun was battling an evil lord named Kaiser Hades. After a long fight between good and evil, Nolun's army won and Kaiser Hades was sealed somewhere on Earth. After so many years, Kaiser Hades returns with his partner named Dr. Zora. Both of them decide to conquer Earth and send monsters such as the Zakoal, the Cyber Knights and his large monsters named the Space Beasts to attack Earth. Seeing this, Nolun gives part of her powers to Shouta, Yuka and Shinya so they can transform and become the Justirisers. Armed with special powers and the Genseishin and supported by Mio, Reika and many other humans, the Justirisers are on the mission to defeat Kaiser Hades and his army.—wikizilla

The second of Toho and Konami's ChouSeiShin trilogy, Gen Sei Shin Justiriser debuted in 2004. Years ago, the evil Kaiser Hades was defeated and sealed away by a champion of justice named Noulan and her mystical "Justipower". Her mission complete, Noulan entrusted her Justipower to a future generation in case evil ever arose to threaten the Earth once again. Now in the modern age, the evil alien Doctor Zola sets in motion a plan to free Kaiser Hades from his bindings. In response, the Justipower chooses three champions to defend the planet and gives the power to transform into Justiriser: Shouta Date (Riser Glen), an underachieving high-school student who finds purpose in his new role; Yuka Sanada (Riser Kagari), a popular high-school student who feels conflicted between her newfound responsibility and desire to lead a normal school life; and Shinya Hiraga (Riser Gant), a straight-faced college student who dislikes fighting and questions whether humanity is worthy of protecting. Together they are the Justiriser, the chosen champions of Earth with gaining the ability to generate powerful armour and summon Humongous Mecha known as Phantom Star Gods.—TVTropes
