 :A redirect is better than nothing because it gives some information about the person. If I only know about one series they have been in then I direct to that series. If someone notices that someone has worked for more than one thing then with 2 notable things someone has participated in I think that is enough grounds to create an article about the person. I didn't have the time to do any googling for Rin Asuka to find out if she had done anything else. Since you were looking for her, do you know of any other things she has acted in which have articles here? I am definitely interested in upgrading this from a redirect into a full article about the actress. I think this is better than just deleting it. If you would tell me how you found out about her and wanted to look for her then we could use that to create an article. 

 :If there is not actually an article about a person then people should not make their name into a link. Redirecting the person's name to where they are mentioned on Wikipedia (a notable role) is good, but linking to their name when there's no article (creating a red link) and just leaving it would not be good. Shouldn't the dispute be with the person who made it into a link without checking if something was there first? Anyway, I'll take the initiative to do a little research about her to create an article. When people bring this to attention it is good because it encourages article creation. I would like to take similar steps with other actresses. The redirects are basically a starting point for an article, something I would link to once the article is fully realized.    
 ::You are not aware what the purpose of the red link is. That is why I linked you to WP:Red link, a policy/guideline/whatever on Wikipedia. Having these actors who could possibly get into more notable roles (as I believe Rin Asuka has done, I just need to see if it is the same Rin Asuka) have their articles as red links is more useful than having them as redirects to articles that have absolutely nothing about them other than one role they portrayed. That is why these redirects you ahve created are useless to the project. At least users can see where the red link goes and comes from using Special:Whatlinkshere rather than have one page that is not about them define them.—  "
