I believe you may be referring to Fuyumi Ono (小野 不由美), a Japanese novelist best known for writing the fantasy series "The Twelve Kingdoms" (十二国記, Juuni Kokuki). However, if you are indeed asking about Fumino Hayashi, I must inform you that there seems to be a lack of prominent information regarding an author with that specific name. There might be a possibility of misattribution or confusion with another author. Please provide more details or check the name, and I'd be glad to help with the correct information. If you are looking for information about another author or a person related to literature with a similar name, please clarify so I can assist you accordingly.
