The "Mikachan" typeface/font was used for Ame Manga's English translation. http://www.mia-lab.com/mf/
I wanted to know this for years.
But I don't know about the person who translated it.
The English translation is quite odd as well. I don't understand it.
Or perhaps the Ame Manga is just like that. I wouldn't know without talking to a native Japanese speaker.
