Now, if we dive a bit deeper into her personality, there’s a strong case to be made that Isana Higashira aligns with the INFP personality type. At first glance, she seems outgoing, but beneath that energetic surface, there’s a thoughtful and introspective side to Isana. She often reflects on her feelings and relationships, showing a level of emotional depth that’s typical of INFPs. Empathy is another big trait—she genuinely cares about how others feel, sometimes putting their emotions ahead of her own. That kind of selflessness? Classic INFP material.

Plus, let’s not forget her creative streak. Isana Higashira expresses herself in unique ways, especially through music. She composes songs that reflect her inner world, using art as an outlet for her emotions. This artistic sensitivity is another hallmark of the INFP type. And while she can be bold in pursuit of love, she also avoids unnecessary conflict, preferring harmony over drama. That desire to keep peace, even at the cost of confrontation, fits well within the INFP framework.

When we look at her through the lens of the Enneagram, Isana Higashira appears to resonate strongly with Type 5—the Investigator.

She spends time exploring her interests, diving into intellectual pursuits, and observing the people around her. There’s a quiet intensity to Isana Higashira that reveals itself in those reflective moments when she’s not trying to win attention.

Her fear of being seen as incompetent drives her to seek knowledge and mastery, especially in areas she values.
