Let’s talk about Asuma Mutsumi — a character who might not be the main focus, but definitely leaves a lasting impression in the anime Kiss Him, Not Me. Asuma Mutsumi is a second-year student at the same school as Kae Serinuma, the series’ protagonist, and while she isn’t the center of attention, her presence brings warmth and energy to the story. As a member of the school’s swimming team, Asuma Mutsumi balances her athletic life with being one of Kae’s closest friends.

Now, what really stands out about Asuma Mutsumi is her cheerful and kind-hearted nature. Honestly, it’s hard not to like her — she’s upbeat, optimistic, and always seems to know just how to lighten the mood. Whether it’s through a well-timed joke or simply showing up when someone needs support, Asuma Mutsumi consistently shows that she cares. Her bubbly personality doesn’t just make her a fan favorite — it makes her an essential part of the group dynamic.

And speaking of support, loyalty is one of Asuma Mutsumi’s strongest traits. She’s not the type to turn her back on a friend, especially not Kae. Throughout the series, Asuma Mutsumi is there with advice, encouragement, and even a shoulder to lean on when things get tough. She genuinely wants the best for the people around her, and she’s not afraid to step in when something feels wrong. In fact, her strong sense of justice often pushes her to act, even if it means putting herself at risk. That kind of courage? It’s rare, and it makes Asuma Mutsumi stand out.

As the story unfolds, we also get to see a more personal side of Asuma Mutsumi — her growing feelings for Nozomu Nanashima, one of Kae’s close friends. Sure, there are misunderstandings and awkward moments along the way, but Asuma Mutsumi doesn’t give up. Instead, her affection becomes clearer, deeper, and more determined. Watching her navigate this romantic journey adds another layer to her already rich character.

When you look at her overall personality, it’s interesting to consider how Asuma Mutsumi might fit into certain psychological frameworks. For instance, based on her behavior, Asuma Mutsumi could very well be classified as an ISTJ personality type — introverted, sensing, thinking, judging. Now, that might seem surprising given how friendly she appears, but take a closer look. Asuma Mutsumi tends to be thoughtful before acting, often observing first and stepping in only when she has a clear plan. She values order and efficiency, which shows in how she handles both team responsibilities and personal challenges.

Moreover, Asuma Mutsumi approaches problems logically, sometimes coming off as reserved or even blunt — not because she’s unkind, but because she prioritizes practicality over emotion. And while she enjoys her friendships, she also clearly values time to reflect on her own, a trait typical of introverts. So, even though she’s social in key moments, Asuma Mutsumi seems most comfortable when she’s got control, structure, and a solid plan — classic signs of a Judging and Sensing preference.

Then there’s the Enneagram angle. If we go by her emotional patterns, Asuma Mutsumi fits quite well into Type 6 — “The Loyalist.” This type thrives on security, trust, and dependable relationships, all of which resonate deeply with Asuma Mutsumi’s actions. She’s incredibly loyal, yes, but she also experiences moments of anxiety and doubt, especially when facing big decisions or uncertain outcomes. It’s not that she lacks confidence — rather, she wants reassurance that she’s making the right choice, particularly when others are involved.

In romantic contexts, this tendency becomes even more apparent. Asuma Mutsumi’s interest in Nozomu isn’t just about attraction — it’s tied to a deeper need for connection and stability. She may hesitate to express her feelings fully at first, worried about rejection or misunderstanding. That fear of abandonment, common in Type 6s, can sometimes lead to overthinking or seeking constant validation. But again, this doesn’t diminish her strength — instead, it makes her more relatable.

All in all, Asuma Mutsumi is much more than just a cheerful side character. Her blend of positivity, loyalty, quiet determination, and inner vulnerability gives her real depth. Whether she’s supporting Kae, standing up for what’s right, or quietly figuring out her feelings for Nozomu, Asuma Mutsumi remains a consistent and heartfelt presence throughout Kiss Him, Not Me. And when you piece together her ISTJ tendencies and Type 6 motivations, it becomes clear that Asuma Mutsumi navigates the world with care, responsibility, and a deep desire to belong.
