Fudou Nomura/Relationships

Due to his personality, Nomura has established various relationships with all characters throughout the series. He is capable of earning the respect from the girls in Supreme Five Swords after being able to defeat them one by one (Inaba Tsukuyo is the special case, as he is no match for her yet).

Onigawara Rin
He started off at a bad start with Rin as he openly rebelled against being corrected and dressing like a girl as the other boys did. He fought against her and ended up defeating her in the battle and kissed her by accident which shocked both of them. She also gets jealous when other girl get to close to him and is the common tsundere. As the series progress, they have formed a close bond as comrades who trust each other when in combat.

It is unknown if he actually has romantic feelings for her but he actually respects her and is protective of her when he said about Tamaba Satori making Onigawara Rin cry after she framed him.

Kikakujou Mary
The two started off on a rocky start with Mary thinking that Nomura was a simple pervert like the rest. Though this was taken out of the equation, when Mary told Nomura to fondle her breasts for losing to him. When Nomura declined and stated he would not be coaxed into anything like that, she devised a way to get him to touch her breasts through a means of putting her stamp in between her breasts. Though tempted, Nomura once again refused such actions and stated that he would not do such a thing.

Realizing that not all men seek to satisfy their carnal desires, she submitted to him and declared herself to also be his supervisor alongside Onigawara Rin. It was shown in episode 8 that Nomura should do whatever he wanted to her body. Once again, Nomura declined stating: "Nah, I'm good.". It has been shown that she is interested in him and is considerably jealous when Nomura doesn't acknowledge the changes she made to herself. Following this, it appears Mary has developed feelings for him which deepen as the series progresses.

Tamaba Satori
It is unknown when she started to have romantic interests in him. By kissing him without any thoughts and not feeling afraid when she was being naked before Nomura. She also seems to care deeply for him, like protecting him from Tsukuyo when he was all exhausted and carrying him to the infirmary when he passed out, but she also likes to tease him sometimes. When she was in danger in front of Amou she thought about Nomura-chan and she wished if Nomura-chan could be able to come to save her.

Inaba Tsukuyo
At their first time face-to-face, Nomura underestimated Tsukuyo a little because she is a middle schooler and his fights against other members of the Five Swords, whose abilities are quite equal, were not too hard. However, after failing to see her draw out her sword and put it back to its scabbard, he immediately realized in fear that he cannot win yet. She and Nomura studied similar sword style therefore have a certain respect for each other, but Nomura discontinued his training because of his adopted father's physical abuse to him. She constantly rants about his mistakes in his fighting style (which Nomura put up with since he didn't complete his training).

Other Classmates
At first, the girls all viewed him as a delinquent like the other boys at the school and were nervous around his presence. One of the male students Masukodera who became his roommate advised Nomura to follow the rules of the Supreme Five Swords but the latter refused to comply as he felt free to do as he pleased at school. After Nomura defeated and accidentally kissed Rin, their dislike grew and Nono, the right-hand woman of Rin wanted to inflict pain on him and was joined by Choka the right-hand of Mary but they were easily defeated and humiliated. When Masukodera was kidnapped by Hanasaka Warabi, a majority watched as Nomura fought to free him even taking down Kyo-bo, a bear before defeating Hanasaka Warabi herself. Following this, Nomura's reputation changed as the female students started fawning over him impressed by his strength and consideration for his friend.

Amou Kirukiru
In the past before transferring into Private Aichi Symbiosis Academy and becoming known as the "Empress". She pretended to be a man and controlled the school as she was obsessed with the concept of dominance, in that school she met the newly transferred Nomura. They started off as good acquaintances as she acknowledge his abilities and may be at some point considered him as a friend.

This relationship did not last long however as Nomura made a new friend which he saved from a group of bullies. His friend decided to repay the favor by showing him around the school. Amou heard this conversation and decided to show him around the school herself in order to know more about him, which Nomura rejected as the latter already decided to go with his new friend. This rejection triggered some feeling on Amou which can be taken as jealousy. This jealousy leads to her hurting Nomura's friend that starts a fight that made them get transferred in the first place.

That conflict continued at Aichi Academy when Amou beat other girls due to their "close" actions to Nomura. It was over only when he explained to everyone about friendship and managed to defeat her. Upon hearing of Amou having transferred to another academy, Nomura caught up with her at the airport to see her off. There, he felt happy because she always likes him from the beginning, and him too.
