I apologize, but "tobu18kio" doesn't appear to be a word or have any specific meaning in Japanese or any other common language. It looks like it might be a combination of characters or possibly a name, but without more context I can't determine its meaning or provide any relevant information.

If you meant to ask about something specific related to this term, could you please provide more context or clarify your question? That would help me give you a more accurate and helpful response.
