Kazuma/Relationships

Bishamon
Kazuma cares greatly for his master. He is immensely loyal to her and wishes to protect her. However, he is willing to confront her if necessary, for her own sake or for the sake of his fellow shinki. Vaisravana, in turn, seems to view him as an equal instead of a subordinate, asking him for advice and considering and valuing his opinion. He is also very precious to her because he is one of her blessed shinki.

Interestingly enough, the manga hints at some romantic feelings he might have towards his master, from the incredibly interesting background he has on his cellphone to becoming ballistic should say master ever disappear. He is also shown to be protective of her and goes as far as to kill one of the Shinki to preserve her health. In Chapter 38, Yato stole his phone and states how Kazuma has nothing but a hoard of photos of Bishamon. She was deeply hurt and betrayed when she discovered that he had assisted Yato, her enemy. Although it was a normal course of action, she did not excommunicate him; instead, she exiled him. He came back despite his exile upon learning of her fight with Yato being orchestrated by Kuguha and confronted her, hugging her and revealing the truth. He admits he was the one who hired Yato to kill his shinki clan to protect Bishamonten and that Yato was not at fault at all. He also admits he felt he is worthless because after asking Yato to slay the Ma clan, he was going to reveal his treachery to Bishamonten but when she told him she only needed him he felt a sort of happiness hearing that and decided to let her continue hating Yato so she could heal. After learning that he was the one who begged Yato to kill her shinki to save her from being blighted and begged for her forgiveness, she decided to stop his exile and he has since returned by her side. In some ways, he is somewhat similar to Bishamonten as he is shown to hate Nora like most characters of the series and as a result, hated the idea of having to bow to a Nora to save his master (As Yato's only shinki at the time was Nora) just as how Veena hated Yato because he saved her twice and how she couldn't protect her two shinki clans and had to rely on a no-name God to save her. He has also stated on several occasions that she is the only one who can hold his name. The fact that he has so many photos of her, even on his smartphone as mentioned in chapters 38 and 39, heavily implies he has feelings beyond a master and servant and that he holds her in romantic regard but doesn't act on those feelings, possibly since he feels that would infringe upon their relationship as master and servant, her status as a God in contrast to his lower status as a shinki, and the fact that, as stated in chapter 7 of Noragami Shuushuu the seven gods of luck are not allowed to get themselves involved romantically.

Yato
Kazuma describes Yato as his "benefactor", saying that he "owes him a debt". He cares for Yato, going so far as to ask Hiyori to look after him.

Kazuma once asked Yato to dispose of Vaisravana's old Shinkis, due to them being corrupt to the point of almost killing her. He is greatly indebted to Yato. He also asked Hiyori about Yato's condition due to the action of Yukine thus stating that Yato should slay Yukine. Later, Kazuma went so far as to help Yato in his Purification Ceremony, even though he was Vaisravana's greatest enemy.

However, after learning Kuguha was the one behind spreading blight amongst her Shinki and herself in order to kill her and resurrect her and then overthrow her while killing off all of her Shinki whom he deemed useless, Bishamonten helps to save her remaining Shinki and releases Kazuma from exile, desiring instead for him to be her guidepost and mending their relationship.

However, both Kazuma and Yato still have a friendly relationship. Kazuma teaches Yukine and Yato often comes over to Bishamonten's house to watch the two practice. Even when Kazuma is deemed an enemy by Yukine, Yato defends him, saying that just as much as Kazuma saw Yato as a benefactor, Yato saw Kazuma as a benefactor. This reason being after Yato killed the Ma clan, Kazuma hid Yato from Bishamon. He also brought Yato food and hung out with him.

In Chapter 78 of the manga, Kazuma becomes Yato's shinki, thus becoming a Nora in the process.

Hiyori Iki
Kazuma trusted Hiyori enough to request that she look after Yato, as he did not want to lose his benefactor.

Later, Hiyori would recognize him as one of the few Shinki willing to help Yato with his Purification Ceremony. She trusted him enough to call on him on Yato's behalf in the latter time of dire need. He seems to care for her as shown when her soul and he are kidnapped by Kuguha and locked away, he worries about her health since if her soul stays out too long she will die. The two have less interaction afterward but seem to view each other as friends. When Yukine declared Kazuma an enemy, Hiyori was saddened to see their relationship turn sour and wanted the two to make up.

Yukine
Kazuma helped with Yukine's ablution and Yukine has been grateful since. He felt bad about exposing Kazuma's helping to save Yato, causing Yato to be blighted due to Yukine's negative feelings. After Yato and Bishamonten let go of their grudges towards each other, starting in Chapter 27 Yukine asks Kazuma to become his teacher. Kazuma accepts as the two are both blessed shinki and while he does tease Yukine, Yukine respects him as a teacher and his superior while Kazuma sees him as a worthy ally and friend. However, their relationship starts to turn sour when Yato's father threatens the heavens and after he strikes Tsuguha causing her to regain her memories and fall ill. Kazuma implicitly threatens Yukine to tell him who the sorcerer is but Yukine refuses since Yato will die if the sorcerer does. While Kazuma initially respects this, after Tsuguha turns into an ayakashi, Kazuma forcefully uses Resound on Yukine to tell him where the sorcerer is, causing Yukine to dub him an enemy. Kazuma even considered doing it a second time in Chapter 57 (to Kugaha), though Tsuyu prevented it. In Chapter 59, when he was frantically looking for Bishamonten, Kazuma asked if they were willing to tell him who the sorcerer is and if not to stay out of his way.
