rename kotona_matome -> ichijoji_kotna
I don't think "matome" is part of the character's name. I could only find it written in hiragana (まとめ) at Twiman (sorry, I can't figure out how to show individual posts for that site, but Ctrl+F should work). Using Google Translate, I get "Summary of Kotona-chan" for コトナちゃんまとめ and "Summary of Liz" (actually Liz-chan) for リズちゃんまとめ. I read somewhere that まとめ is used to mean "collection" on Japanese websites.
The official romanization of her name seems to be Kotna Ichijoji, with Ichijoji being the surname, as shown in her character profile at post #6073004.
