Maria Momoe is a well-loved character from the anime series Big Windup! (also known as Oofuri: Ookiku Furikabutte), where she stands out not just for her bright presence but also for the meaningful role she plays within the team. While Maria isn’t on the field swinging a bat or throwing pitches, her contributions are no less vital—she’s the dedicated team manager of the Nishiura High School baseball team, and honestly, it’s hard to imagine the squad succeeding without her steady support.

Right from the start, Maria Momoe shows up as someone who genuinely cares. She’s cheerful, warm-hearted, and always seems to know exactly what to say when a teammate is feeling down. Whether it’s organizing equipment, scheduling events, or simply offering a kind word, Maria Momoe goes above and beyond to make sure everything runs smoothly. And even though she doesn’t wear a uniform, her knowledge of baseball is impressive—she pays close attention to strategy, player conditions, and game dynamics, proving that her value extends far beyond basic managerial duties.

It’s no surprise that so many members of the Nishiura team look up to Maria Momoe. She has this quiet strength about her—an ability to lift spirits with just a smile or a few encouraging words. Her positive attitude is contagious, and honestly, you can see why fans of Big Windup! have grown so fond of her. Maria Momoe may not be in the spotlight during games, but her behind-the-scenes efforts are absolutely essential to the team’s morale and cohesion.

When we take a closer look at her personality, there’s a strong case to be made that Maria Momoe fits the ISTJ personality type—Introverted, Sensing, Thinking, Judging. Now, don’t get me wrong—she’s friendly and approachable, but she often works best independently, quietly handling tasks with precision. Maria Momoe is extremely organized, detail-oriented, and relies heavily on logic and practicality rather than emotions when solving problems. These are all classic signs of an ISTJ. She follows routines, values responsibility, and approaches every situation with a sense of duty—whether it’s making sure the water bottles are filled or reviewing game stats.

What really stands out is how structured and efficient Maria Momoe is. She sticks to plans, keeps meticulous records, and expects things to be done properly. That’s the Judging trait shining through—the need for order and reliability. Even in high-pressure moments, she stays calm and grounded, using facts and past experiences to guide her decisions. It’s clear that Maria Momoe’s ISTJ tendencies help her excel in her role as team manager.

But that’s not the only lens through which we can understand her. From an Enneagram perspective, Maria Momoe strongly aligns with Type 2—the Helper. This makes perfect sense when you consider how much she gives of herself. She’s empathetic, nurturing, and constantly tuned in to the emotional needs of others. If someone on the team is struggling, Maria Momoe is usually the first to notice and the first to offer support. She finds deep satisfaction in being needed and valued by her teammates.

Still, this desire to help can come at a cost. Sometimes, Maria Momoe puts everyone else’s needs ahead of her own, possibly to the point of neglecting her personal boundaries. There’s a subtle vulnerability there—she might avoid asserting herself if it risks upsetting someone else. While her selflessness is admirable, it also hints at a deeper need for validation and connection, which is common among Enneagram Type 2s.

In the end, Maria Momoe is more than just a supportive figure in Big Windup!—she’s a character who embodies dedication, empathy, and quiet strength. Whether viewed through the MBTI or Enneagram framework, her traits paint a picture of someone who thrives on service and stability.

But based on her consistent behavior throughout the series, the ISTJ and Type 2 labels fit her remarkably well.

All in all, Maria Momoe leaves a lasting impression—not because she’s loud or flashy, but because she’s dependable, kind, and wholeheartedly committed to her team. In a show centered around teamwork and growth, Maria Momoe stands as a quiet yet powerful example of how support roles can shape success just as much as the players on the mound. And honestly, that’s why fans continue to appreciate Maria Momoe for who she is—a true heart of the Nishiura baseball team.
