Lie Ren/Affiliation

Beacon Academy
Lie Ren is a first-year student at Beacon Academy.

Team JNPR
Lie Ren is a member of Team JNPR.

Nora Valkyrie
Lie Ren is Nora's childhood friend, as well as her classmate from both their previous school and Beacon Academy. He is occasionally bothered by his friend's hyperactivity, which sometimes makes him angry enough to raise his voice, but he does show her genuine affection and sees her as a valuable friend.

Ren also appears to be the only person able to keep Nora's thoughts in the moment, snapping her out of her imagination when claiming their relic. He also sometimes seems to occasionally get somewhat annoyed by her, as seen when she drank the jar of sap he handed to her after filling it up.

Pyrrha Nikos
Pyrrha Nikos is one of Lie Ren's classmates at Beacon, as well as a teammate in Team JNPR. They did not have much interaction, for they were initially in separate groups. In battle, they have not displayed any notable level of teamwork.

As seen in "Forever Fall, Pt.2" and "Burning the Candle", both Ren and Nora know of Pyrrha's feelings for Jaune, although Ren seems content to let Nora talk to Pyrrha about it.

Jaune Arc
Jaune is Ren's classmate and team leader. They have not had much interaction, though they think similarly. This takes form in the Beacon Academy Initiation when Jaune realizes that Ren is trying to weaken the Death Stalker's stinger so that it may be driven into its head. Also, Ren is quick to point out how Jaune has acted since started doing things for Cardin Winchester, which was why he was being so discrete and often returned to his dorm late.

Ren has agreed with Jaune on the state of their friendship, Jaune describing them as great friends and "the brother I never had", despite Ren's quiet nature. While not much can be said or seen to how true this is, Ren encourages Jaune to get to the heart of the matter and listens to what he had to say before Pyrrha takes over. He has also shown to be loyal to his leader and accepts Jaune's orders without question.

RWBY
Although little interaction has been seen among them, Lie Ren, like his team, appears to be on friendly terms with RWBY, for during Jaunedice, they are seen eating lunch together.

In Best Day Ever, Ren joins his team in a food fight against them, but they are eventually defeated. However, he shows no signs of ill will and is even seen laughing alongside his team after its conclusion.

Ren has also made note of Team RWBY's skills, remarking that they have always been successful on the field. As such, he seems to demonstrate a sense of respect for them.
