Iwashimizu is a very tall young man with amber eyes and chin-length blonde hair. He is rather lanky for a forward, especially at the beginning of the series, but he grows more muscular as time goes on. It is said that Iwashi always wears a worried expression. He is blushing more often than not, and his eyes frequently appear glassy.
His usual school uniform consists of a white button-up shirt, black trousers, and an optional black gakuran, which he prefers to carry around rather than wear. His uniform is too small for him, but he's too ashamed to have it replaced as he's already had to size up so many times.
During matches, he wears a tight-fitting red jersey with Jinkou's kanji written on the left pectoral, two black stripes around the chest, and a white collar; the jersey has a white number 5 imprinted on the back to indicate his position. He also sports white shorts and spikes, as well as black tape around his thighs to increase friction when the props lift him during line-outs.
Iwashimizu generally wears comfortable loungewear on his days off, such as loose t-shirts and joggers. In the winter, he opts for a sweater layered over polos. He owns a Jinkou Rugby Club windbreaker, but he rarely wears it as even the largest size is too short for his figure.
Iwashimizu is a timid, sensitive wallflower. He would typically much prefer books to sports, but he is quite devoted to rugby. Initially, this was merely an extension of his devotion to Miyuki, but it grew into a genuine passion for the sport after he joined the high school team. Rugby also provides a healthy outlet for his surprisingly short temper.
Being an introspective person, Iwashimizu has a tendency to overthink. He has a noticeably hard time making decisions on his feet and is often singled out by his opponents as being slow. He struggles a lot with insecurity and anxiety; he spiraled into a severe depressive episode after the incident with Miyuki. It took longer for Iwashimizu to mentally recover from the guilt than for Miyuki to physically recover from the injury.
Iwashi is highly encouraging toward his friends. He always lends a listening ear when they have something to complain about, and he has been shown to become very sentimental when he feels they are growing as people, so much so that he tears up over seemingly insignificant details, like when he started crying after hearing Sekizan and Hachiouji's meeting story. Furthermore, his subservient and self-effacing nature entails he often get pushed around by the more dominant personalities of Miyuki, Gion, and Ooharano, but he doesn't seem to mind this and is usually content enough just being included. In fact, it is often said that his rugby performance is merely a reflection of the skill and spirit of his teammates; at the beginning of the series he couldn't tap into his competitive energy without someone else riling him up. With all of that being said, he is the protective type; while he rarely contests when he himself is being walked over, he does not tolerate anyone mistreating his friends.
He is self-conscious about being so big and tends to worry about taking up too much space or getting in others' way. Before the start of every game, he checks if there is anyone on the opposing team that appears to be taller than him.
On Iwashimizu's first day of middle school, he meets Miyuki Atsushi, who invites him to the rugby club on behalf of his height. Though Iwashi had never been the athletic type, Miyuki's enthusiasm and bright smile persuade him to join. It is here that he also meets third year Hachiouji Mutsumi and fellow first year Oku Yuuri, the latter of whom takes an immediate disliking to him that would last the entirety of middle school.
When Iwashimizu is in his third year, Miyuki becomes the captain of the team. They have an incredible winning season up until a scrimmage just before the prefectural finals: while holding the ball, Iwashi bulldozes straight through Miyuki, fending off an attempted tackle. Miyuki, in turn, suffers a broken shoulder as he hits the ground, meaning he's out of commission for the rest of the season. Azuma loses their next game and does not qualify for the national tournament. Miyuki swears that Iwashi doesn't need to feel guilty—it was an accident, after all—but Oku, who was then the vice-captain, blames him for their loss entirely. In the end, Iwashimizu resigns from the club, planning to quit rugby for good.
Due to a combination of the guilt from the incident itself and the loneliness from cutting off his friends, Iwashimizu spirals into a depressive episode. At school, he appears nervous and absent-minded. He does everything in his power to avoid his former teammates, especially Miyuki and Oku. At home, he is despondent; his mother notes that he hardly ever leaves his room during this period. Funnily enough, this is about the time he becomes infatuated with the romance genre.
During the orientation ceremony, a few upperclassmen whisper about Iwashimizu's staggering height. He has barely made it to his locker after school when he bumps into a group of unnamed third years, who badger him for taking up so much space. He frantically apologizes, and the third years crack a few jokes about his balls being too small for the rest of his body before promptly deciding someone of his timid nature would make the perfect lackey. It is then that Gion, another first year whom is more than 30 centimeters (1 foot) shorter than Iwashimizu, enters the hall. As he struggles to reach his high locker, the third years turn their attention to him, at this point howling with laughter, as they call him a shrimp and make a few creative comments comparing the two freshmen.
Suddenly, Gion jumps the upperclassmen, offended that they called him a shrimp. He starts to attack them, but Iwashimizu picks him up over his head, the upperclassmen assuming he's going to throw Gion at them as a weapon. Then, having intended to disperse the fight before anyone could do any real damage, Iwashi runs away. They exit the building like this, and Iwashi continues to run until Gion's struggling grows powerful enough to knock the both of them over. Gion yells at Iwashi, questioning why he had to go and pick him up, to which Iwashi meekly says Gion was going to get hurt if he hadn't stepped in.
When Iwashimizu thanks Gion for sticking up for him, the latter responds by saying that he was just pissed about the short jokes; Iwashi just happened to also be getting picked on. He claims to hate cowardly types like Iwashimizu. The two finally introduce themselves and begin walking toward the main building, Gion once again shouting at Iwashi for a moment under the assumption Iwashi was following him, before promptly realizing they absolutely had to go in the same direction. They walk in silence for a bit and start speaking at the same time, only for Iwashimizu to skittishly usher Gion to go ahead. He laments about how being held up so high gave him perspective on how much tall guys can see and do compared to him. Suddenly, he loses his temper and jumps onto Iwashi, grabbing him by the shirt, hounding him about what kind of diet he has that made him grow so big. In his anger, he opens up about his insecurity that everyone is looking down on him because of his height.
Before the conversation can continue, Hachiouji tackles Iwashi from behind, trapping Gion beneath him. Hachi exclaims that he didn’t expect Iwashimizu to be attending his school and asks if he’d hit another growth spurt. Then, Gion makes his presence known by popping out from under Iwashi. After introductions, Hachiouji asks if Gion wants to come to the rugby club with he and Iwashi.
At the rugby ground, Hachiouji joins the scrimmage at practice. Gion had never heard of rugby before, so Iwashimizu explains the basics of the game: carry the ball to the opponent’s goal in order to score, and use brute force to take the ball back if the opponent is the one carrying it. Iwashi tells him he was scouted because big guys like him have an advantage, but really anyone could be the star no matter if they were tall, short, fat, thin, or anything in between. Gion is mesmerized at the idea of being able to steal the ball from someone huge, but Iwashi grows anxious and begins rambling about how dangerous rugby is.
When the scrim ends and Hachiouji returns, Gion declares he’s going to join the rugby team and demands that Iwashimizu teach him everything he knows. However, Iwashi declines and begins to walk away, claiming he won’t be joining the rugby club because he doesn’t play anymore.
The next day, Iwashimizu attempts to join the literature club. All is well until Gion barges into the clubroom, shines a fake smile, and drags him to the rugby field. Since everyone else is out recruiting new members, the pair has all of the ground and equipment to themselves. Gion tosses a tackle bag at him, effectively forcing Iwashi to be his training partner. Iwashi is intimidated by how quickly Gion started wanting to tackle, since it is typically something new rugby players are scared of. Gion then decides that Iwashimizu should tackle him first as a demonstration, and the latter voices a concern that Gion would get seriously hurt if someone Iwashi's size were to tackle him.

Offensively, Iwashimizu is as fast as a Number Eight and have great upper body strength, his powerful shoulder barges and fend offs (stiff arms) can hurt.
In terms of differences between the two locks, as a Number-5, he is the closest receiver in a line out, which unlike a Number-4, who is often directly behind him that would hook the ball with his hand to the Scrum Half, his job is to secure the ball to set up a maul, but his big hands meant he can do so with just one hand, but he often chooses to hook the ball to the halfback as well to speed up the game. Since he is not heavy for a lock, he is often taken out by opponents in defensive lineout, or be completely thrown off-guard when opposing hookers aim for the other lock, or throwing it even further back to negate him.
"The Iwashi Lift" Choke Tackle
Tag-Team Tackle: Overpass
Iwashimizu begins to tackle an opponent. In the few seconds while he's still in the air, his feet serve as an overpass for Gion to dive beneath, taking out said opponent's ankles while he is distracted by Iwashi's size.
Gion thinks Iwashimizu is a coward. He always shouts at him and gives him a nickname "Udo". Despite all of that, they have a fairly good relationship. But in turn, given Gion's fiery temper, Iwashimizu has to pick him up to flee the scene, so they won't get into more trouble. Iwashimizu truly cares about Gion and seems to understand him better than any other team members. Iwashimizu also seems to have a lot of respect and love for Gion as seen in the manga. In chapter 15 of volume 3 Iwashimizu is shown running to find Gion as soon as he heard Gion was no where to be found, this shows his care for Gion.
Iwashimizu initially started playing rugby when Miyuki invited him to join the middle school team. Iwashimizu harbours regret after he broke Miyuki's shoulder in a middle school practice, which made him fearful and unmotivated to play rugby. But they both defend each other from Gion's retorts, but both Gion and Miyuki constantly motivates him to give it his all.
