Looking deeper into his personality, many fans and analysts believe Kaito Domoto fits the ISTP personality type. Now, if you’re familiar with personality typology, ISTPs are often seen as practical, independent, and highly resourceful individuals. They tend to be hands-on problem solvers who thrive on logic and action rather than emotion. And yeah—that sounds just like Kaito. Think about it: he’s skilled at diving, fishing, and even fixing his own boat. He doesn’t wait around for help; he dives in (literally and figuratively) and handles things himself.

But like any ISTP, Kaito Domoto isn’t without his complexities. He can seem distant or reserved at times, which might make him appear aloof. He doesn’t wear his heart on his sleeve, and expressing emotions isn’t exactly his strong suit. Sometimes, he acts on instinct—bold moves, yes, but not always thought through completely. That impulsiveness? It’s part of what makes him human, and honestly, kind of relatable.

Then there’s the Enneagram angle. Based on his behavior, Kaito Domoto also lines up closely with Type 8—the Challenger. These types are bold, self-assured, and natural leaders. They hate feeling powerless and will go to great lengths to maintain control over their lives. Kaito definitely shows that fierce independence and determination. When trouble arises, he steps up without hesitation. He takes charge, protects others, and pushes forward no matter the odds.

Yet, being a Type 8 comes with its challenges. Kaito’s desire to stay strong can sometimes make him seem overly dominant or intense. His fear of vulnerability might cause him to shut people out, especially when emotions run high. It’s clear he struggles internally with opening up, even to those closest to him. That inner conflict—between strength and sensitivity—is a big part of what makes Kaito Domoto such a compelling character.

All in all, whether you’re analyzing him through MBTI or Enneagram lenses, one thing remains true: Kaito Domoto is a layered, dynamic individual whose actions and personality leave a lasting impression. From his role as Lucia’s protector to his dreams of musical adventure, and even his internal battles with emotion and control, Kaito Domoto embodies a rare blend of strength, passion, and quiet devotion.
