This one lowers your heart rate on purpose. Sora opens a crate his self-declared adventurer father shipped home, and out climbs a mummy small enough to sit in his palm, and from there the show's entire ambition is making sure that little guy stays dry, fed, and unafraid. The stakes are things like keeping Mii-kun away from water and letting him help with chores he's far too tiny to do, and the series treats that with total sincerity instead of milking it for gags. It grows outward gently: Conny the pocket-sized oni, Isao the baby dragon, a friend group defined by who they take care of rather than what they want. Yes, the first few episodes wander before it finds its shape, and nothing here will spike your pulse. But the payoff is the specific ache of watching a kid who was lonely realize he isn't anymore, because something the size of his hand needs him.

Sora Kashiwagi gets more than he bargained for when his globetrotting father, a self-styled adventurer, ships him an enormous package from Egypt. Out of it climbs Mii-kun, a mummy only 12 centimeters tall who fits in the palm of Sora's hand. Sora is wary at first, but the little mummy turns out to be harmless: timid, quick to cry, eager for attention and very cute. What unfolds is a gentle supernatural comedy about everyday life with an unusual pet, as Sora and Mii-kun grow closer and meet other people who keep strange companions of their own.
