 (the following are spoilers for the story. if you can, please play the VN first as it's not very long)

 

This girl's own personal history is full of sad memories. Her parents kept her locked up, and never paid any attention. Then an old man named Analye decided to take her off their hands. From there, her life got slightly better. She was still shut up inside, this time in the church basement with only a bed. But this time she also receives attention. He would read her books and other things. With time, Analye became her Pops, though never really her father. But Analye was also lazy, so eventually he drops her off at Blackiris's apartment. He lets her bathe, buys clothes her, and guides her around town. For the first time, La experiences something of a normal life. That is, normal as the City can provide, for only Mnemonicides and their Guests are allowed to live inside it. She remains hidden because she has no permission to be here.

 

When she has to go back to the church, Blackiris tells La she can come back to his place anytime, an offer which she takes up. Every day during evening hours she comes, to read his books. Until one day Analye mentions to Blackiris that he has a use for La. After that, she stops coming.Curious about her absence, Blackiris pays a visit. He meets with Analye, who reveals that La is an Omega, which is the most powerful Mnemonicide on the scale, even stronger than the top Alpha class. While those classes can only at best make sad memories go away for a long time (to hold back Psyche Corrosion, a type of epidemic depression that always inevitably leads to suicide), the Omegas take in all the memories into themselves. 

 

It's for this reason that La must remain hidden Alaye took her in, because he is an Omega himself: the legendary so-called "Alpha of Omegas". He planned to transfer all the sad memories he picked up into her instead. Naturally, Blackiris isn't pleased at the old man's plan, so Analye gives Blackiris a gun to shoot him with. But Blackiris cannot bring himself to pull the trigger and he runs away. Several days later, he returns to the church and finds La and Analye together. Too late, La's taken in all his memories and he dies, leaving La a crying mess hunched over Analye's body. Her hair has turned white from all the grief but she refuses Blackiris's offer to erase them.

 

(The game doesn't go into detail about what happened to her from then on, but it's implied her and Blackiris's memory of the incident was erased. Eventually she comes to work under Dexter.)

 

Years later, Blackiris is given a new house, and it's there he meets La, who is his new client. This kicks off the main story. La and Blackiris live together even though opposite-sex Guide/Guests are forbidden, where they get roped into Rook's schemes, take in a Guest who sneaked in illegally, and deal with underground terrorists. After a month of this, La decides to start erasing his memories, for it turns out Blackiris is her client and not the other way around. But Blackiris refuses to forget. He then remembers that La is the "kitten" he took in long ago and they kiss. After that, the two of them deal with Dexter and run away from the City.
