Olivia is one of the main trio of Asobi Asobase. Along with Hanako and Kasumi, she makes up the Pastimers Club. Olivia is unable to speak English because, despite having foreign parents, she has lived in Japan for a long period; however, having missed the opportunity to come clean about it at the start of the school year, she maintains the lie that she is good at English and bad at Japanese, despite being fluent in the latter.
