Kogasa Tatara's sole purpose is to surprise people. However, she hasn't been very successful so far. Kogasa is currently reading up on classic ghost stories in order to improve her scaring technique, but after gaining weight she adds squashing to her repertoire. Kogasa is a cheery happy youkai,, but gets easily depressed when things don't go her way (which is very often), typically when she fails to surprise someone despite her best efforts. Likes to rock around on those she is sitting on.
