I have used "Aiko" as a Japanese alias ever since I got into anime and manga and it turns out that it means about the same thing as my actual name, but I never used it on forums before because the name was so common that it was bound to be taken on all the larger forums. But I have decided that I wanted to start using it again, and I had initially thought about using "Aikou" but I decided against it because there was still a chance of that name being taken and it would change the meaning of it entirely seeing as that's not how it's spelled in kanji, and I replaced the "u" with an "h" instead since that was an old way of romanizing the "ou" sound that's not quite as common anymore. The "ou" sound isn't a correct romanization, no, but at least with the "h" the meaning won't be changed and I can still use the name. Well, it works!
