Hi, Witaku and welcome to Wikipedia. I was not the one who deleted the article you created. I tagged it for deletion because it lacked notability  and it was subsequently deleted by an administrator after review. A Google search for "Nyrva Dragonrhyne" produces only 7 hits  that is hardly "a lot." Two of the hits are deleted wiki pages and the other 5 are from self-published websites: facebook and deviantart, neither of which is a proper reference source. I think if you wish to write articles about fictional characters, it would be a good idea to review some of the Wikipedia guidelines for notability, such as Wikipedia:Notability (fiction)#Elements of fiction. And check out some of the articles about notable anime/manga characters already included in Wikipedia, such as Usagi Tsukino and Belldandy. This can help you in determining the suitability of future articles. Good luck
