Although Komei is a maid, he is very sloppy, so he will only give things a standard clean, instead of making things ultra clean like Sims with a high neatness score.
Komei has 0 interest points in Sci-Fi, which is typical for deceased Sims, but not for adult townies and NPCs, as they typically have 4 interest points in Sci-Fi. This happens with many NPCs from the tutorial neighborhood. Often going unnoticed, he has 22 personality points, instead of the usual 25.
