I’m Not a Succubus! Vol. 3 picks up right where the previous volume left off, thrusting our very human protagonist, Sakura, further into her ridiculous and risqué life at a monster girl academy. Pretending to be a succubus while trying to avoid drawing suspicion is hard enough, but things only get more complicated as her classmates—many of them actual demi-humans—begin to grow closer to her. This volume leans into its character-driven comedy while also giving us some sweet, unexpected moments of depth.
A major focus this time is Sakura’s developing relationship with Tamako, the class’s spider-girl who prefers to go by Reon. Reon’s infatuation with Sakura becomes much more prominent in this volume, leading to some truly wild and awkward scenarios. But surprisingly, Reon isn’t just played for laughs. There’s a quiet sincerity in how she navigates her feelings for Sakura, and for all the fanservice and mischief, their connection adds heart to the story. Watching Sakura try to handle Reon’s advances without blowing her cover makes for some of the most memorable scenes in the book.
Other standout moments include interactions with Ai, the sweet cyclops girl who struggles with depth perception. A scene where Sakura helps her out ends up unintentionally intimate, and it’s one of those perfect comedic beats that the series nails so well. Nina the lamia also gets more screen time, with her unique concept of a “warm person” adding another wrinkle to the complex (and hilariously confusing) web of relationships Sakura finds herself trapped in.
The student council president and vice president make their formal debut in this volume, adding a new layer of tension and intrigue to the setting. Through their interactions, the story explores demi-human family structures and the expectations placed on students who come from powerful bloodlines. These characters aren’t just here to shake things up—they provide a different lens through which to view the monster world Sakura’s trying to survive in. Their presence suggests there may be more structure, and maybe even bigger consequences, in Sakura’s future.
One of the things that stood out in Volume 3 is how it tones down the more over-the-top eroticism in favor of character development. That’s not to say the series has gone chaste—far from it. There are still plenty of risqué scenes and absurd misunderstandings, but the focus this time seems to be more about letting the cast grow. We see stronger bonds forming, secrets deepening, and Sakura’s identity as a “non-succubus” feeling like a ticking time bomb as more people get attached to her.
The humor continues to be a highlight. From misinterpreted kindness to monster-specific gags involving anatomy and culture, the series blends worldbuilding and comedy with surprising finesse. Sakura remains a loveable mess of stress and blushing reactions, and each chapter continues to deliver laughs while subtly building a bigger narrative.
Visually, the manga still looks fantastic. The character designs are playful yet detailed, and the contrast between Sakura’s increasingly frazzled expressions and the sultry confidence of the monster girls is comedy gold. Action scenes are minimal, but the expressive art during emotional and comedic beats keeps everything feeling fresh and energetic.
I absolutely loved this volume and can’t wait to see how the series continues. I’m Not a Succubus! Vol. 3 strikes a great balance between spicy humor and heartfelt moments, and it’s clear the cast is only going to get more entertaining as the story progresses. Whether you’re here for laughs, monster girl lore, or to see if Sakura can keep her secret for one more semester, there’s a lot to enjoy in this series—and I’m hooked.
