Yui/Relationships

## Family

### Kayaba Akihiko

Kayaba is Yui's creator. Not much is known about their relationship, but Yui seemed really confused when Kayaba locked her away and prevented her from interacting with the players when the death game started, effectively preventing her from doing her job.

### Kazuto Kirigaya

Kirito is Yui's in-game adoptive father. During the start of their relationship, they were both using each other for their personal goals: Kirito was using Yui as a pawn for his mind game with Asuna and Yui was observing both Kirito and Asuna to understand the meaning of love.

However, Kirito grows to become attached to Yui, seeing her as his own daughter and willing to do anything to protect her. When he thought she was dying, Kirito saved Yui's data as an in-game item in order to save her, in hopes of bringing her back and spending time together like a real family.

Kirito found out later that Yui faked her "death" as a joke to try to lighten the any tension or view changes between her and her adoptive parents, much to Kirito's annoyance. When Kirito explained to Yui the situation with Asuna, Yui became obsessed with finding her as soon as possible, an obsession that scared Kirito.

### Asuna Yuuki

Asuna is Yui's in-game adoptive mother. She first met her when she woke up one day to find her in her bed. She initially wanted to have her arrested for breaking and entering, but she ended up using Yui as a pawn for her mind game with Kirito to get him to admit that they got married too soon.

Unbeknownst to her, Yui was observing both Kirito and Asuna to understand the meaning of love, as their relationship contradicted her data on the subject. However, Asuna grows to become attached to Yui, subconsciously thinking she's adorable and eventually seeing her as her own daughter and willing to do anything to protect her.

When she thought she was dying, Asuna broke down crying in a rare moment of weakness. When Kirito saved Yui's data as an in-game item in order to save her, in hopes of bringing her back and spending time together like a real family, Asuna was overjoyed to the points of tears, despite her best attempts to act tough.

When Kirito explained to Yui the situation with Asuna, Yui became obsessed with finding her as soon as possible, in order to reunite as soon as possible.

### Suguha Kirigaya

When Yui first met Leafa, Yui saw her as a threat to her family dynamic and was incredibly hostile, calling Leafa a hussy and threatening to harm her if she got in the way. When Leafa became Kirito's companion, Yui proclaimed that she wouldn't hesitate to leave the Sylph player behind should she get in the way. Despite this, Yui did respect Leafa in some capacity, as seen in her psyche evaluation of her, but she lost some of this when she realized that Leafa wasn't as bright as she thought.

Yui would eventually discover that Leafa was Kirito's sister in real life by hacking into her account (technically making the latter, the former's aunt). When Yui realized that Leafa was starting to mess with Kirito instead of helping him, she explained to her what was really going on, but after this didn't work, she removed Leafa's face, coercing the latter into helping Kirito for real.

Yui later asked for Leafa's help protect Kirito while she hacked into the system. Leafa was hesitant to do so, due to her issues with her brother, and Yui used her skills as a psychiatrist to help Leafa get on the path of repairing the siblings' relationship. During this, Yui tugged on Leafa's heartstrings by calling her "Auntie Sugu", which Leafa felt was cheating.

Although, this might've been Yui manipulating Leafa to get what she wants, as she later calls Leafa a "smooth brained charlatan" due to her wasting seven hours of their limited time. Despite Yui being mad at her, she didn't reveal Leafa's secret identity to Kirito, so it's unclear where the two actually stand. Leafa later got over her fear of Yui when she realized that her threats sounded cute.

## Allies

### Yulier

As an AI, Yui's opinion of Yulier was very critical. Yui stated that if Thinker is the smartest man she's met then she must not have had many great male role models in her life. This comment enraged Yulier to the point that she wanted to fight Yui.

### Thinker

Although Yui did not interact much, Yui did not have a high opinion of Thinker. She stated that it was ironic that his name was Thinker as he didn't seem very smart to fall for such an obvious trap.

### Shinichi Nagata

Yui seems to like Recon, as when she pulls up her psyche evaluation of Suguha she makes a note of their relationship, calling him a "poor, sweet boy" that deserves respect.

## Enemies

### Nobuyuki Sugou

Although she has not met him, Yui has an intense hatred for Nobuyuki, as he is a threat to her family dynamic. When she found out that he had trapped Asuna in ALO she made an objective for herself to kill him in order to save Asuna.
