Story Overview

Sora Kashiwagi's father is a globe-trotting adventurer who sends him bizarre things from his travels — and has a talent for terrible timing. This time, he's sent an enormous Egyptian sarcophagus. From it emerges a mummy. A tiny, palm-sized, incredibly cute mummy, so small it fits in a tea cup, with enormous eyes and a personality hovering between shy and absolutely desperate for affection.

Sora names him Mii-kun and, despite his initial reluctance (he is a high school student living alone, and a mummy was not on his agenda), finds himself completely devoted to his new tiny roommate.

As the story progresses, Sora's friends acquire their own mythical creature companions — an oni, a dragon, a tengu — and the group navigates the particular joys and challenges of caring for creatures who are small, easily startled, and deeply loving in their helpless way.

Characters

Sora Kashiwagi: Responsible, a little tired, genuinely kind. He's the archetypal "I can't say no to something that needs me" protagonist. His growing affection for Mii-kun is drawn with real warmth.

Mii-kun: The mummy. I cannot overstate how precisely Kakeru Utsugi has drawn this creature's emotional expressiveness. Mii-kun communicates enormous feeling with minimal features — mostly just eyes and bandages — and every expression is readable and perfect. When Mii-kun is happy, you feel it. When Mii-kun is scared or lonely, it's devastating in a way completely disproportionate to how small he is.

Kamoda and Connie: Sora's friends, each with their own mythical companion. Their dynamics provide variety and contrast to the central Sora-Mii-kun relationship.

Asa: Sora's childhood friend who manages a mythical bakery of sorts. Her competence and warmth are a nice grounding force in the series.

Art Style

Utsugi's character designs for the mythical creatures are the star of the show. Mii-kun especially is a masterwork of cute design — the proportion of head to body, the size of the eyes, the way the bandages are drawn with slightly irregular texture that makes him feel material and real. The human characters are appealing but conventional; the creature designs are genuinely inventive.

The art style is soft and warm overall, with gentle line weights that reinforce the comfort-reading atmosphere. This is a manga that looks the way a blanket feels.

Cultural Context

The "healing" (iyashi-kei) genre of manga is specifically Japanese — stories designed to provide comfort and emotional relief through gentle content. How to Keep a Mummy is a textbook example, and understanding it in that context helps explain why the low-stakes plotting is a feature rather than a bug.

The mythical creatures — the mummy alongside Japanese folklore figures like oni and tengu — reflect an interesting cultural crossing. Mii-kun is Egyptian, but he's been adopted into a Japanese household and a story organized around Japanese slice-of-life rhythms.

What I Love About It

There's a chapter early in the series where Mii-kun has a bad dream. He wakes up frightened, and Sora — half-asleep, barely awake — reaches out and pats him back to sleep without fully realizing what he's doing. Just automatic, instinctive comfort for a small creature he's been responsible for long enough that it's become reflex.

I read that chapter on a hard day. I'm not sure I can explain exactly what it was about watching a teenager comfort a tiny mummy in the middle of the night, but it helped.

How to Keep a Mummy doesn't pretend problems don't exist. The characters have difficult moments — loneliness, failure, worry. But it insists that small good things — warmth, presence, something small that trusts you — are real and worth having. That's not naive. That's true.

What English-Speaking Fans Say

English-speaking readers consistently describe How to Keep a Mummy as a "comfort read" they return to when life is hard. The most common review structure is some version of "I read this when I needed something gentle and it helped."

Mii-kun is universally adored. Readers frequently say he's one of their favorite fictional characters, full stop. The bar for that praise is set by his emotional expressiveness — readers feel they know and care about him as an individual despite his size and the limited vocabulary of his emotions.

Some readers find the plot too low-stakes, but most embrace this as the point. "It's okay that nothing dramatic happens because it's wonderful that anything happens at all" appears in various forms in many reviews.

Memorable Scene ⚠️ Spoiler Warning

Late in the series, there's a storyline where Mii-kun becomes temporarily separated from Sora and must navigate on his own. The chapters are surprisingly tense — not because anything terrible happens, but because Mii-kun is small and frightened and determined. Watching a creature that tiny decide to be brave is disproportionately moving. When he finds his way back, the reunion is one of the series' emotional peaks.
