Tatsuki Iizuka

Daughter to the corporate president of E-lectra, one of the biggest electronics company in Japan, she lives in a modest-looking house with a housemaid, separate from her parents due to her father's work. Ever the classy one, she tends to use honorific speech even towards her closest friends and is often annoyed by Torako's mischief. Her name contains a kanji of dragon and the first kanji letter of her name is pronounced as 'I' (East). Thus, revealing her name's relationship with Azure Dragon of the East.
