People make typos and incorrect edits all the time and you can see it on anyone's profile, but no one is going to care. Wikipedia and other editable sites are the same way.
Google will update its cache with a newer version of the page eventually. And it's not like you can pollute search results with one typo, google algorithms are more robust than that. Although I guess technically you can in this case since I can't find this Hinami person to begin with, they return no results with any other spelling I try. You created the first result yourself lol.
