Wonderful list! I really appreciate that you wrote in some detail if the character is canonically ace as in, the word(s) is said, if it's more implied with the character actively saying they're not interested/don't experience attraction, or that it's implied due to their lack of romantic relationships and interest in them.
I also have a suggestion for a character! Onodera Takara from Kimi no Hana ni Naru/I Will Be Your Bloom which has the same screenwriter as Koisenu Futari and Cherry Magic. He has a support role but is part of the main cast. He is semi-canon aroace and his lack of interest in romance is brought up twice, both with positive and accepting reactions from his friends. I'll quote what he said: "I'm honestly not interested in love at all. [...] I'm happiest when I'm dancing."
Wow! I'll be saving this article because I love a good strong and well developed friendship in a drama. I find that most of my all time favourite drama's have those type of friendships. Reading this article has given me a lot of ideas for other shows to watch (or finally continue and maybe finish this time).
One drama you maybe would like to keep an eye on is the Japanese drama Koisenu Futari. There are 4 episodes that have been released so far. The two main characters (a woman and a man) are aromantic and asexual and due to events in life they decide to live together and see if they can become like family but without the typical romance that one would expect between a man and a woman. It's really good and funny so far, and dives into topics like 'what is romance/when/why is something romantic' and 'what makes someone family'.
