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. 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. Yeah

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. Once again, Nomura 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. It is unknown at this time, the extent of Mary's feelings to Nomura, although the former has a bit of a crush on the latter as the series progresses.

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.

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 member 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 the scabbard, he immediately realized that he cannot win yet.
