In fact, he consistently puts his teammates before himself, showing just how selfless he truly is.

Now, when we look at Iwashimizu Sumiaki’s journey in All Out!!, things start to get interesting. When he first joins the rugby team, he’s not exactly eager to dive into full-contact play. There’s a backstory there—something from his childhood left him with emotional scars and a deep hesitation around physical confrontation. But here’s where things shift: inspired by Sekizan, the passionate captain of the team, Iwashimizu decides to face his fears. And honestly, that moment marks a turning point—not just for him, but for the whole dynamic of the team. Thanks to his impressive size and raw strength, Iwashimizu Sumiaki quickly proves to be a crucial player, someone the team can rely on when the pressure is on.

One of the most powerful themes in All Out!! is the unbreakable bond between teammates, and Iwashimizu Sumiaki embodies that idea perfectly. Over time, he grows into a rock-solid presence—someone who doesn’t seek the spotlight but quietly supports everyone around him. His loyalty? Unshakable. His dedication? Off the charts. And when he’s on the field, that combination of inner strength and team-first attitude makes him a force to be reckoned with.

He’s the kind of character who stays with you, reminding us all that teamwork and perseverance can carry you through even the toughest challenges.

From a personality standpoint, Iwashimizu Sumiaki seems to fit the ISFJ type pretty well. He’s definitely introverted—quiet, thoughtful, and not one to draw attention to himself. Yet, he carries a deep respect for tradition and takes his responsibilities seriously. That sense of duty? It shines through every action he takes as part of the team. Plus, he’s incredibly empathetic—always aware of how others are feeling and ready to step in if someone needs help. You could say Iwashimizu Sumiaki thrives on stability, too.

Then there’s the Enneagram angle. If we had to categorize him, Iwashimizu Sumiaki lines up closely with Type 6—the Loyalist. This makes a lot of sense when you think about it. He’s naturally cautious, always scanning for potential risks or dangers, both on and off the field. Security matters deeply to him, which is why he often looks to leaders like Sekizan for guidance and reassurance. His loyalty to the team is one of his defining traits—exactly what you’d expect from a Type 6. But this same need for safety can sometimes hold him back. In unpredictable situations, Iwashimizu Sumiaki may struggle with anxiety or indecision, wrestling with doubts before taking action. Still, those vulnerabilities make him feel real and relatable.

So, wrapping it all up, Iwashimizu Sumiaki is far more than just a strong player in All Out!!. He’s a character shaped by loyalty, fear, growth, and deep connection to others.
