Who Is Kanna in The Guy She Was Interested in Wasn't a Guy at All?
The Guy She Was Interested in Wasn't a Guy at All (Japanese: 気になってる人が男じゃなかった) is Sumiko Arai's award-winning yuri manga about Aya Oosawa, a fashionable high-school girl who falls for a stylish record-store employee — not realizing that person is her quiet classmate Mitsuki Koga. While Aya and Mitsuki carry the romance, the series gradually widens its cast, and Kanna is one of the supporting students who becomes part of their orbit as school life and music culture collide.
Kanna's arrival matters for pacing: the early chapters focus tightly on Aya and Mitsuki's mistaken-identity tension, and new classmates like Kanna give the story room for group comedy, jealousy beats, and fresh perspectives on the leads. For readers tracking the series through the official KADOKAWA manga page or the English volumes from Yen Press, supporting characters like Kanna are where the slice-of-life texture of the series really develops.
Kanna's scenes are most enjoyable after you understand the central misunderstanding between Aya and Mitsuki. Start from Volume 1 so her interactions land with full context.
The table below places Kanna within the broader cast structure:
| Character | Role in Series | Relationship to Kanna |
|---|---|---|
| Aya Oosawa | Gyaru-style lead, outgoing and expressive | Schoolmate; part of the same social circle |
| Mitsuki Koga | Quiet lead, record-store worker, androgynous style | Schoolmate; admired from a distance |
| Kanna | Supporting student character | Provides comedy and outside perspective on the leads |
| Other classmates | Background and group-scene characters | Widen the school-life setting |
How Kanna Fits the Story's Themes
Kanna, like the other supporting students, helps the manga explore its recurring themes without derailing the romance. Three thematic functions stand out:
Outside Perspective
- Views Aya and Mitsuki from a normal classmate angle
- Highlights how unusual their dynamic appears to others
- Fuels comedic misunderstandings
School-Life Texture
- Grounds the story in everyday high-school scenes
- Balances the record-store music world with classroom life
- Supports the slice-of-life pacing
Relationship Catalyst
- Creates situations that push the leads to react emotionally
- Adds tension through attention and admiration dynamics
- Keeps group scenes lively
The series won the Web Manga category at the 2023 Next Manga Awards, and its success comes from exactly this balance: a tight two-person romance surrounded by a believable school and music-community cast.
Character Comparison: Kanna and the Main Cast

| Connection to music | Discovering alternative rock | Deep knowledge, works at record store | Peripheral to the music plotline |
| Story function | Romantic lead, pursues the mystery | Romantic lead, hides her identity | Expands cast, adds comedy |
| Screen time | Highest | Highest | Supporting |
| First appearance | Chapter 1 | Chapter 1 | Later chapters |
Kanna's most significant scenes appear in volumes beyond the first two English editions. This guide deliberately avoids spoiling late-story developments — check the Yen Press series page for the latest volume availability.
