Well... this is easy. She is from The Melancholy of Haruhi Suzumiya... Now here u go some info about her.
Tsuruya is the hyperactive friend of Mikuru (from the current time plane) notable for her loud voice, ankle-length hair, and prominent tooth. She possesses a cheerful and friendly disposition. She is also prone to long fits of unrestrained and intense laughter at things she considers even the slightest bit humorous. Her fang-like tooth gives her an idiosyncratic speech pattern, causing her to misspeak words 由 leaving out syllables, as seen in episode 9. Her speech pattern is often accompanied with a lisp and her catch phrases "megas" and "nyoro". Her knowledge of the SOS Brigade comes almost exclusively from Mikuru. 来源 MAL
