Final Fantasy Tactics A2: Grimoire of the Rift
Luso Clemens is a student known for his mischievous streak. Just before the school's summer break, Luso was sent by Mr. Blair to help Mr. Randell, the school's librarian, to clean the library as punishment. Mr. Randell was not in when he arrived, so he took the opportunity to explore. Luso found a mysterious book on the table with its pages empty, save for an inscription asking the reader to write the name of the one who would finish the book. Luso did just that with his own name, and was immediately warped to the world of Ivalice. Luso appeared in front of a Crushatrice and its Cockatrice flock, but it also happens that Clan Gully, led by Cid, was at the scene. To help him, Cid urged Luso to join his clan, summoning a Judge to help with the process. Luso was made a Soldier, and helped Clan Gully defeat the Crushatrice.

During one of the quests he took with the clan, Luso and Cid discover that he had with him a magick journal. Luso recalls the mysterious book that brought him to Ivalice, and they concluded that a magician named Lezaford may know about the truth of the book. Luso then takes a quest where he eventually meets up and is joined by the infamous Adelle the Cat. Adelle accompanies him in the quest after Cid is injured on a nighttime stroll while trying to find information on Lezaford's whereabouts.

Adelle and Luso eventually found Lezaford at the Aldanna Range, where the mage took a closer look at Luso's journal and declared it to be a grimoire, a magickal tome that had the power to return Luso to his world. Lezaford assured Luso that he would only need to fill out the grimoire's pages by living out his live in Ivalice as best he could. Luso concluded that the best way to do this was to take every possible mission available at the Pub.

During one of those missions at Tramdine Fens, Luso was infected with a wayward spirit that began to haunt his dreams. After defeating the Oversoul at the Nazan Mines, some of Luso's memories are available for the player to see. Adelle learns that Luso's parents have died and that he was raised by his aunt, a woman who worried after Luso's tardiness often.

Luso eventually met the Nightshade Illua at Zellea, the Forbidden Land, and defeated her and the Neukhia that spawned out of her grimoire. By doing this, his grimoire was completed, and he was allowed to return home. His friends gathered at Targ Wood, the site of Luso's appearance in Ivalice, in order to see the Judge send him off in a column of light. Upon returning to the school library, Luso immediately told his story to Mr. Randell, who believed him (as Mr. Randell had previously been sent to Ivalice in Final Fantasy Tactics Advance, though a different kind) and allowed Luso to keep the grimoire. Luso continued to use the book as a journal, recording not his adventures in Ivalice, but those of his own world.

Trivia

 * A voice in Luso's point of view could be heard at the Japanese trailer of Final Fantasy Tactics A2: Grimoire of the Rift, though it is unknown who the voice is.
 * On various occasions, Vaan refers to Luso as "Red Cap".
 * If his name was not coincidental enough, Luso's clothes resemble the green, yellow, and red from the Portuguese flag.
 * There was once an old plot by the development team that Luso was the last villager of this village, with the other villagers gone away or died. They abandoned this plot point in the sense that it was too dark, however, this plot may have been used for Adelle's backstory when she speaks to Lezaford the second time, as she alludes to a plague wiping out her whole village, with herself being the only survivor due to her being a Gifted One. Ironically, his eventual plot point is often criticized for being childish.
 * Luso is afraid of ghosts, which he is teased for by Adelle in a mission. This is also brought up by random encounters with ghosts as predominant enemies. Instead of Luso saying the usual "Ack! We're under attack!", he would ask, "H-Hey, that wasn't a ghost, was it?".
