I've seen a few episodes, and I have to say I wasn't too impressed. It felt like a diet version of Doraemon, with many of the characters coming across as watered-down versions of Doraemon characters. One notable exception was Rui Ijigawa, a character I genuinely liked. She did have a stylish clothing sense, which somewhat reminded me of Suneo from Doraemon, albeit as a girl. Despite the similarities, Rui managed to bring her own unique charm to the series.
If you're in the mood for an anime centered around a child receiving assistance from a non-human companion in their everyday life, I'd highly recommend checking out Doraemon, either the 1979 or 2005 anime adaptation. It executes this concept much more effectively than Taruruuto ever manages to, and you'll notice that Doraemon's characters have a depth and charm that most Taruruuto's characters seem to lack.
