Suiten Inori/Relationships

Demon Lord Knights
Patricia Caesar - The leader of the Demon Lord Knights, Inori and Patricia were good friends, until another personality arose from within Inori, when Inori petrified the entire school, she did petrify Patricia but not fully since she wanted to play with her friend mind. Patricia found her magic is very powerful when the petrification accelerated, before completely turning to stone she told Inori that it can't be helped since it's her thema and magic. She didn't hold a grudge on her, upon Inori redemption, their leader hugged her. Surprising her, after all the terrible things she's done to her, they became friends again afterwards along with the other Demon Lord Knights.

Yumegaya Chris - Chris views her as a very good friend, even after Inori petrified her and nearly killed her by pushing her. She felt enjoyment in doing so. Despite the fact, being her first friend, this is due to Inori's personality and apathy, which she admitted she doesn't understand all these feelings, friendship, bonds and passion. Even after mentioning she is a kind and caring person. Nevertheless she didn't care about her. This is not until she regretted petrifying her and nearly killing her, that they reconciled with her and the other Demon Lord Knights. Becoming friends again.

Mamiya Yorun - The only friend she didn't petrify and viewed her as an ally, different from the other Demon Lord Knights Yorun protected her from Ana's sword, which shocked Inori. Yorun mentioned to her she is similar to her, she used to be all alone without anyone paying attention to her. Inori found her mistakes afterwards, and that friendship is important. Yorun hugged her friend along with the other Demon Lord Knights. Yorun was also the one who invited her to become friends with them, so in a way Inori is indebted to Yorun.

Others
Lilith Asami - Lilith was her teacher, and she studied hard under her. At first when she attacked the students and petrified them they were enemies. Even though she wasn't petrified. Inori fought with her, whom Lilith found her magic is very powerful. She didn't pay much attention to Lilith, and with Inori apathetic nature, she would later eventually petrify her. However upon her defeated, Lilith is freed along with the others. She later becomes friends with her teacher and listens to her plans, and cooperate with her.

Anastasia-L - Ana at first weren't even friends with Inori. Inori tried to murder Ana at any way possible and not because she was ordered to do. She even sent meteorites at her, petrified her arms and broke it. However Ana anticipated this, summoning Astral Trinity which Inori cowers in fear when she sensed his mere presence is more powerful than her. Ana then overwhelmed Inori and to wake her up from her apathetic state, she resolved to slash her, only for Yorun to take the slash. Surprising Inori at her action. Despite Inori best effort to defeat the Saint, she failed to do so. After Inori's defeat she would later become friends with her.

Arata Kasuga - After Arata was reincarnated into Demise World as a child, she along with the other Demon Lord Knight became his teacher. She did teach him about mage knowledge, which after few days of training with them and her he became adept in doing so. She is then seen glad at his progress.
