I read The Saint’s Magic Power is Omnipotent Volume 3 earlier this year, but I didn’t say much about it at the time—mostly because I wasn’t even sure I wanted to keep going with the series. Now that I’ve picked up some interest in Volume 4, I figured it’s time to share my thoughts. And honestly? Volume 3 might be the weakest entry in a series that already isn’t known for strong plotting—and a lot of that comes down to how little it actually matters in the grand scheme of things. This volume feels like a side story. Which would be fine, really, if it gave us more meaningful character moments or put Sei in new, interesting situations that let her grow. But that’s just not what happens. The dialogue meanders, nothing leads anywhere, and while events technically unfold, they’re so uneventful that—no joke—the highlight of the entire book is Sei cooking pasta. And I honestly think that was supposed to be the big moment, considering how much time is spent on her asking to use the kitchen, cooking, and everyone being blown away by how amazing pasta tastes. Which… brings its own narrative issues, but we’ll get there.
To give the book some credit, changing the setting to the Klausner Domain had potential. It’s isolated, which could have offered a fresh angle on Sei as a character—especially since it’s tied to the late apothecary master from previous volumes. It could’ve been a great opportunity to show Sei outside her usual environment, doing something new. But unfortunately, that never really happens. She barely does any new research, doesn’t grow much as a person, and the worldbuilding is basically non-existent. The only “new” piece of information we get is the confirmation that Sei’s magic is powered by love and Albert is the emotional trigger—which we learn through a diary. But even that isn’t surprising, since it was already heavily implied in Volume 2. It’s nice to have confirmation, sure, but we didn’t need a whole new setting just for that—especially when the diary could’ve been anywhere.
The bigger problem is that this new setting doesn’t add anything. It disconnects the story from everything that came before without building anything new in its place. The result is a volume that feels self-contained in the worst way: like filler. And that feeling is reinforced by the fact that basically nothing progresses. One thing I really appreciated in the first two volumes was how Sei gradually found her place—learning alchemy, taking on new roles, meeting people, getting caught up in bigger questions about her identity as the Saint. Now, that mystery’s solved, everyone knows she’s the Saint, which you’d think would spark some kind of internal reckoning. But instead, she just… keeps doing what she was doing, without any real reflection on how her role has changed. Her development is all external—other people treat her differently, but she doesn’t process or respond to that shift in any meaningful way. It makes her feel strangely passive, especially compared to the version of Sei who actively carved out her path in the earlier books. The one proactive choice she does make—joining the expedition to Klausner—is framed as her wanting to learn from the apothecary’s legacy. But even that feels thin, because the story doesn’t give her much to actually learn. And maybe that’s part of a bigger issue: Tachibana clearly wants this to be a romance series at heart, but the romance here is barely present. Sei does start realizing she has feelings for Albert, and we’re told her Saint magic activates when she thinks of him—but Albert himself barely shows up. Without shared scenes or moments, there’s no emotional weight, and nothing new develops. The book gets caught up in a bunch of smaller episodes that don’t deepen the world, the characters, or the romance—so I’m left wondering what it was even trying to do.
It kind of feels like Tachibana had a few plot points she wanted to get across, but no clear story to frame them with. Ironically, in the afterword, she blames Sei herself for not being good at romance. Which is… odd, considering it was the author’s decision to put her in a remote location with no access to Albert and barely anything else to do. Sei is a great character—smart, curious, emotionally grounded—but this volume gives her almost nothing to do, she just floats through it. And the side characters don’t help. They were never the series’ strong suit, but here they’re particularly forgettable. Previous volumes at least gave Yuri and Aira something to do. In this one, none of the established characters make much of an impact, and the new ones are incredibly flat. Corinna could have been a mentor figure, someone who gives Sei a different perspective as another woman in a male-dominated world—but she’s barely a presence. Leonhardt exists mostly to flex. And Klausner himself, despite being the lord of the domain, doesn’t do much to advance the plot or challenge Sei in any way. There’s a subplot about an herb shortage, but it never really goes anywhere.
To be fair, one thing I will say is that Tachibana tones down the repetitive exposition a bit here. There’s less information dumping than before, which is nice. But when the information we do get feels so narratively irrelevant, it’s not exactly a win. And look—I’m not against slice-of-life. I actually like quiet, character-focused stories. But those moments still need to be something: sweet, funny, reflective, emotionally rich, at least a little engaging. When the most emotionally charged scene in the book is Sei putting on an apron and making noodles, something’s off.
So yeah, I really hope Volume 4 turns this around. More than anything, I want to see Sei take charge again—like she did at the start—and for her love for Albert to be something that empowers her, not something that flattens her into a supporting character in her own story. There’s potential here, Sei is worth following. But this volume made it hard to remember why.
