Justice for Love duology

"From a simple story of two siblings' rivalry, to the end of human civilization."

- Official synopsis

The Justice for Love duology (also known simply as Justice for Alicia duology in the Philippines) is a Japanese-Philippine multimedia franchise and fictional universe that is centered on Alicia Salvacion's miserable life and her attempts on seeking justice for herself and her loved ones. Starring Yasmien Kurdi, and mostly set in San Francisco, the duology was produced by Toho and co-produced by GMA Pictures. It is part of the larger Reiwa series.

The duology received generally positive reception in the Philippines and has been commercially successful after earning ₱677 million at the box office.

Development
The concept originated from the 2013 Chelyabinsk meteor event, and the lack of films that visualized the possible effects of a large asteroid impact. Due to the incident, interest in asteroid impact events have drawn renewed attention, while Toho considered producing a film that focuses on such event, with the Cretaceous–Paleogene extinction event serving as the main inspiration for the film.

The film's screenplay was adapted from The Last War, a 1961 film also produced by Toho which showcases the possible scenario of total nuclear war during the Cold War years. As the Cold War ended in 1991 during the dissolution of the Soviet Union, the new screenplay replaces the nuclear warfare theme with contemporary concerns regarding astronomical impact events on Earth, which includes asteroids or comets.

Setting
The duology takes place in two locations, across the Pacific Ocean: Manila, Philippines and San Francisco, California. Additional locations include Saipan, Northern Mariana Islands, and Honolulu, Hawaii. The duology takes place from 1997 until 2020, from Alicia's childhood days, to Clara's impact on Earth.

Influences
The duology is heavily inspired by multiple impact events that took place in Earth's history, such as the Cretaceous–Paleogene extinction event, which is known for wiping out the non-avian dinosaurs 66 million years ago, following the impact of a 10 to 15 kilometer comet or asteroid in the Gulf of Mexico's Yucatán Peninsula. Other events include the 1908 Tunguska event, the largest impact event in recorded history, and the more recent 2013 Chelyabinsk meteor event.

In terms of story, the duology appears to be greatly influenced by the 2014 series Rhodora X, as many aspects in Alicia's story share similarities with the series, most notably in the prequel series. Yasmien Kurdi's character in the duology, Alicia Salvacion, is also heavily based on Angela Ferrer, Kurdi's character in the series.

The 2019 series Bihag served as the main influence for Mylene's subplot and role in the duology. Both the series and the duology feature a scenario where Isabelle Abiera's character gets framed for murder. Also, Jade Lopez's role is the exact same in both the duology and the series.

Other influences on the duology are:
 * Hiram na Anak ― The streetcar accident scene bear similarities to the one shown in the series.
 * Hindi Ko Kayang Iwan Ka ― Alicia's suicide attempt on the Golden Gate Bridge is based on a scene in the series' 42nd episode.
 * Melancholia ― The duology's depression theme was heavily based by this film. Both also feature a depressed woman as the lead protagonist, while Earth is destroyed by a large impact (a rogue planet in Melancholia while a huge asteroid in #JusticeForLove: End of the World).
 * Seeking a Friend for the End of the World ― Some elements of the duology share similarities with the film, such as Mylene befriending Alicia while a huge asteroid threatens Earth, and the story focusing only on specific individuals during a global catastrophe. Also, both have "End of the World" on their titles.
 * The Last War ― Both the film and the duology end at the same way, depicting the ruins of a major city (Tokyo in The Last War and San Francisco in #JusticeForLove: End of the World) before showing a disclaimer stating that the events depicted in the film is a work of fiction that could happen in reality.

Legacy
Due to the continued success of the duology, Yasmien Kurdi was cast as Rebecca de Guzman in the mainstream Reiwa series, which first appeared in Godzilla: The Kaiju Invasion.

The duology has also led to similar works in other media as well, including a parody film that was released in December 2021.
