Overview

Kogarashi Fuyuzora is broke, homeless, and the only living person who can use a specific inherited exorcism technique, which is how he ends up at Yuragi-sou, a rundown boarding house that used to be a hot springs inn. Rent's free if he can banish the ghost haunting the place. That ghost turns out to be Yuuna, a teenage spirit with no memory of her own life or death, and Kogarashi decides pretty quickly that he'd rather help her figure out her unfinished business than send her on. The inn also happens to be full of other supernatural women, ninjas, a cat-god vessel, and more, and Kogarashi ends up living surrounded by all of them while he works Yuuna's case.

Tadahiro Miura ran this for four years in Weekly Shonen Jump, the same magazine that runs My Hero Academia and One Piece, which is a genuinely unusual home for a series explicit enough that Seven Seas released it in English under Ghost Ship, their mature-readers imprint. That mismatch tells you most of what you need to know about what kind of manga this is going in.

What it does well

Yuuna's central mystery gives the story more of a spine than most harem manga bother with. Figuring out who she was and why she's bound to the inn isn't just a backdrop for fanservice episodes, it actually drives the plot forward across the full 24-volume run, and it gets a real answer instead of a shrug at the end. Kogarashi is also a more active protagonist than the harem-lead norm: he's got an actual power set and a concrete reason to be at the center of every fight, rather than just standing around while things happen to him. The supporting cast, ninja cousins with a running rivalry, a girl who channels a cat god, and others, each get enough of a distinct hook that they don't blur together even as the ensemble grows large.

The action set pieces are a genuine draw too. Kogarashi's exorcist abilities and the various tenants' own supernatural powers give the fight scenes real stakes and choreography, which is more than a lot of harem-first series bother to build. It reads as much like a supernatural action manga with a harem wrapped around it as the reverse.

Where it falls short

This is one of the more fanservice-forward series in the genre, and it's upfront about that rather than coy. Expect a steady stream of hot spring scenes, wardrobe malfunctions, and skin, more so than most harem competitors, and the mystery and action elements underneath won't be enough to carry the read for you if that's not what you're looking for.

The cast also balloons over 24 volumes. New girls keep arriving with their own crushes on Kogarashi, and the story spends real time on subplots for characters who never seriously factor into the central relationship, which can make long stretches feel like padding rather than momentum. If you're reading primarily for Yuuna and Kogarashi, some arcs will test your patience.

Verdict

Supernatural harem manga that actually gives its fanservice a plot to hang off of, with Weekly Shonen Jump's usual craft holding the artwork and pacing together. Worth it if you want your ecchi with a real mystery attached and don't mind an ensemble that keeps growing. Skip it if the genre's fanservice conventions are the specific thing you're trying to avoid.
