In the word "Urusei" the final
kanji written for "sei" means "
star" but since it is pronounced sei, it gives the pronounced word a meaning of
annoying, where if you read it it is something along the lines of annoying star, and yatsura means people... therefore it loosely means "annoying star people" or "annoying
aliens". But yes, it is the title of a hilarious
manga/
anime.
