Kasei Hakase left me more let down than delighted, mostly because its early sci‑fi charm never quite grows into anything memorable. The story feels scattered, jumping between Martian antics and slapstick detours without giving either enough weight to matter, and the characters drift through the plot more as props than personalities. Even Tezuka’s usual spark, his warmth, his restless imagination, shows up only in flashes, buried under pacing that rushes past ideas before they have a chance to breathe. It isn’t bad so much as thin, a relic whose historical value outweighs its actual enjoyment, and that imbalance makes it hard to genuinely recommend toanyone but completists.
