Leafa (SAO/Log Horizon AU)

Infinity Moment is a retelling of the Aincrad Arc and the Alfheim Online Arc starting from the last episode, where a glitch prevents Kirito from defeating Heathcliff on the 75th floor. Shortly afterwards on the 76th floor, Leafa, aka Suguha Kirigaya is sent to Aincrad through the use of a spare nerve gear, while trying to to log into ALO, Alfheim Online. Instead, she is sent via game character into Sword Art Online, to Aincrad on the 76th floor where she meets up with Asuna and Kirito, telling them she is Kirito's little sister.

The story continues at a rapid pace, clearing the last 25 floors at a surprising rate, fending off against a newcomer Clearing group which is actually a villainous man named Sugou, who works for RECT in order to try and control the souls of people. Defeating Sugou allows the team to proceed into the 100th floor and defeat Heathcliff once more, for real, ending the death game.

- Summary of SAO Infinity Moment for the PSP

There are many worlds out there, each with their own story. This is one of them.

The developer of the Full Immersion game, Alfheim Online was outsted from his position and his stocks plummeted. This lead to the American developer introduce a new game years ahead of their schedule.

The year is 2022, and Suguha Kirigaya has drifted from her brother. In an attempt to understand him, she began playing the game Elder Tale, in secret. On May 3rd, 2022, the event known as the Apocalypse happened.

Finding herself in the world of Elder Tale with over 100,000 other players worldwide, Suguha assumes the identity of Leafa. It is here that she discovers that in the aftermath, the Adventurers, normal people like she were falling into despair with nothing to do.

While hunting for ingredient animals one day, she discovered a training group lead by a higher up for the guild Hamelin. Realizing that the children were in danger from Hamelin's harsh methods of training, she leaped into action, cutting down the attack monsters. Despite this, she couldn't gain entry to Hamelin's Guild Hall.

Fearing for her friends safety, Leafa approached the Guildmaster Shreider and asked to join, on the condition she cooks for all the kids to keep them healthy. Even though she was unable to produce food that would taste good, she managed to keep the spirits up, until the Jailbreak.

Now without a guild, Leafa returned to the solo life until a member of the West Wind Brigade informed her that the children who were rescued spoke of her, and her kindness. She went to find the children, and found out that two of them, Touya and Minori had gone to join Log Horizon. Despite Maryelle's offer to join, she went to meet up with the two who welcomed her warmly. Together the three of them joined Log Horizon. Leafa began training her chef class once more, thanks to the tutoring of Nyanta who was a superb chef.

Later on, Leafa has a run in with a girl from D.D.D., a new highly skilled recruit called Asuna. She makes fast friends, and discovers they were from the same prefecture IRL after getting to know one another. The pair become close. Asuna also introduces her to Lizbeth, a blacksmith member of The Roderick Firm and they make a semi-permanent hunting party in the aftermath for ingredients and crafting items.

While this is going on, Shiroe learns of a solo player who refuses to join a guild out of some kind of guilt. He sends Leafa to interview the Black Cats, who says that this swordsman accidentally caused a TPK and even though Adventurers revive, he quit out of guilt.

With Asuna and Liz, they track him down where he is and it's a player named Kirito. Managing to save him from a zone boss he aggroed, they took him back to the Cats where he apologized for his stupidity, which they said yes it was dumb but it was also partly their fault.

Kirito is put up with Crescent Moon Alliance for the time being, along with the girl he was helping against, a summoner named Silica who also joined Crescent Moon Alliance.

Leafa continued her training until the training camp, where she joined the kids as a mentor and aid. She was also camp cook, while several others went to talk to the NPCs, the Landers.
