Last Ranker was developed by
Imageepoch. The staff included multiple industry veterans. The game was directed by Kazuya Niinou, who had earlier worked at
Atlus on
Trauma Center: Under the Knife and the original
Etrian Odyssey before joining Imageepoch and directing
7th Dragon. Niinou had a great respect for
Capcom as love of their projects had encouraged him to enter the gaming industry, particularly
Street Fighter II. After Imageepoch entered a production agreement with Capcom, Niinou created the game's design pitch around Capcom's fighting game legacy. The producer was Capcom's Minae Matsukawa, known for her work on the
Ace Attorney series, while established Capcom illustrator Tatsuya Yoshikawa created the character designs. Capcom had long been absent from the RPG market, so Matsukawa wanted to create something original. Yoshikawa described his work on the game as less exaggerated than his work on
Breath of Fire or
Devil May Cry, steering to his preferred style of "muddy" and restrained designs. He described the designs as being inspired by the music and the storyline, and on the requests of senior staff. The Evinos enemies were designed by illustrator Shin Nagasawa, known for his work on monster designs for the
Etrian Odyssey series. Niinou conceived the setting and narrative based on his liking for tournaments between rivals in
shōnen manga. The scenario was written by
Kazushige Nojima, known for his work on
Final Fantasy VII and the
Kingdom Hearts series. While there were several tropes associated with RPGs similar to
Last Ranker, Nojima's scenario was described as an adult take on a shōnen storyline that would avoid genre tropes. Nojima was sending in scripted scenarios once a week, which he found tiring but excited the rest of the staff. He was also unsure about whether he could write for a Capcom title given their history of "crazy" narratives. He modelled Zig's attitude after his own life as a country person who came to the city, inspired by Niinou's description of the character. The cast included a number of notable voice actors. The cast portrayals in-game were influenced by the actors, several of whom discussed the characters during recording. Zig and Faz were played as opposites; Kamiya voiced Zig to be the most impassioned despite a cool exterior, while Nakamura portrayed Faz in a straightforward manner. The voice recording process was described by game staff as emotional. The battle system was designed around the title's descriptive slogan "RPG aiming for the strongest". The faster pace of battles compared to Niinou's earlier menu-based projects was chosen due to the game being developed for
PlayStation Portable (PSP), which Niinou felt was more suited to an action-based combat design. Despite the focus on action in the narrative and battle system, the battle system remained grounded in turn-based mechanics. Niinou wanted to make the battle system and bosses engaging, but still keep it easy enough that players could see the end without grinding. The Seven Knights went through periods of adjustment so they would be a challenge for players without appearing unfair. Developing the system was a challenge for the team due to the one-on-one nature of many battles and its semi-automated design. At Capcom's insistence, stronger versions of the Seven Knights were included as post-game challenge battles. The constant adjustments due to input from Capcom and feedback during testing were negatively compared to running in a three-legged race.
Music (pictured 2008) composed and produced all music for
Last Ranker. The game's music was composed by
Yoko Shimomura, known for her work both at Capcom on titles including
Street Fighter II, and later at
Square Enix and as a freelancer for her work on
Parasite Eve and the
Kingdom Hearts series. Shimomura acted as sole composer and producer, while Hironori Osone arranged the music. She first met with Niinou and Matsukawa, and was enthusiastic by the wish for a battle theme featuring vocals. Niinou's original request was for operatic vocals, but eventually he settled for something that sounded "cool". She was overwhelmed with emotion being able to work with Capcom again, and drew from the feeling of returning to an old workplace or elementary school in portraying the emotions of Zig through the music. She described herself as being "infected" with Niinou's enthusiasm for the project. Some of the music discussions with Niinou and Matsukawa lasted up to seven hours, and she remembered one meeting that ended abruptly when she was struck by an idea and left to write it down. Compared to other projects she worked on,
Last Ranker featured a lot of live orchestral recording sessions. Orchestral recording took place through January 2010. The instruments used for the soundtrack included
piano,
cello,
pan pipes,
low whistle, and
electric and
twelve-string guitars. There was also heavy use of drums, noted as a rarity in Capcom soundtracks. Shimomura combined choral and electronic elements for tracks relating to the alien Evinos. The choral work included Latin-style chanting and female Bulgarian folk singing. English vocals were performed by Joelle Strother, with lyrics by Margaret Lucy. The solo soprano sections were performed by Hiroko Hayama, who also wrote the Latin lyrics. The soprano solos were a very late addition to the soundtrack. During the later recording sessions, several fine adjustments were made to balance out the instruments. Work on the soundtrack lasted a year, and included over forty tracks. The vocal track "Born to Survive" was one of the first tracks to be created, forming the core of the main theme and with lyrics reflecting Zig's goals and passion to become the strongest warrior. She also created an instrumental version of "Born to Survive" titled after one of the song's lyrics "Beyond This World of Woe". The secondary battle theme "Glorious Fights We Call 'Life'" was written as a counterpart to "Born to Survive". "Crudelis et Magnificus", the battle theme for the Seven Knights, was composed as a grand choral work with Latin lyrics setting the combatants and context apart from standard fights. Latin was used again for the track "Fatum Foedus", used for some enemies' special attacks. The theme for Harth's battle, "Be The Last Ranker", combined motifs from all the other battle themes. She gave Yuli a specific character theme called "La Valse Noire", representing his distorted nature; recording was difficult, and the performers required a conductor to get the right tempos. For the theme song, Capcom partnered with rock band
Uverworld. When looking for a collaborator, Uverworld was chosen as their style of music fit in with the world design of
Last Ranker. Their song, "Ultimate", was an original creation written from Zig's perspective. A two-CD original soundtrack album was published by Capcom's music label
Suleputer and distributed by Sony Music on 28 July 2010. The CD included a twelve-page booklet with commentary from Shimomura on each track and messages from Shimomura and the development staff. A limited edition album of five tracks arranged for piano, violin and cello was released alongside the game. One of the featured performers was violinist Ayako Ishikawa. The arrange album came as an early purchase bonus with all editions of the game. Ishikawa performed several arranged themes from
Last Ranker at a violin recital on 17 October at Verbrugghen Hall in
Sydney. A track from the game, "The Bloom of Passion", was featured in a 25th anniversary concert of Shimomura's music in February 2014. "Ultimate" was released on the B-side as part of the single CD release for "
Qualia". Reception of the soundtrack album was generally positive, with critics citing it as one of Shimomura's best compositions. Reactions to the arranged album was less positive, but still noted its musical quality. ==Release==
