Nagisa Hazuki/Relationships

Relationships
Iwatobi High School=

With only three members on the swim team, forming a medley relay team was impossible, so that’s why Nagisa sought out Rei. At first Rei exclaimed “If people evolved to walk on land then it makes no sense for them to return back into the water!!!” but because of Nagisa’s persistent persuasion, he entered the Swim Club. Trying his hardest to catch up with the others along with Nagisa who follows with all his might,  the two make an uneven combination, but only they can eventually calm the tides of the Swim Club.

At first, Nagisa was someone Rei could barely stand because of the way he talks, changes topics very often, is very pushy, super greedy, spills things, doesn't do his homework, messes with other people and drools when he sleeps. Even so, Rei's very thankful to him because Nagisa was the one who invited him into the swim club, and because of that he was able to meet Haruka, Makoto and Rin. He's the reason why Rei was able to notice the beauty of swimming and was the one who "changed his world". In one of the interviews with Rei, he admits that, even though Nagisa is pushy at times, he has an aura that Rei's attracted to and that he has him completely wrapped around his finger.

They both belong to a same class in school and take the same train line to go back home. Nagisa often goes to Rei's home and hangs with him most of his free time. They're often seen doing things together. Rei easily gets manipulated by Nagisa for some reason.
