Final answer:
The term 'Ikioo' does not correspond to any recognized factual data or standard academic subject, making it impossible to determine who has the most Ikioo in the world in 2021 without further context or clarification.
Step-by-step explanation:
The query about who has the most Ikioo in the world in 2021 cannot be accurately answered because the term 'Ikioo' does not pertain to a recognized unit of measurement, ranking, or any known statistical or factual data related to standard academic subjects or global records as of my last update. This could be a typographical error, a non-mainstream term, or perhaps slang that is not widely recognized. It's important to verify the term 'Ikioo' and clarify its context and relevance to provide a meaningful answer.
