A1 used a different pen name back then
Seems "Kirino Mahiro" is his Japanese penname, and that it's still the same guy. Check this out:

Now that you guys mention it, that caricature of the author is the same one A1 uses...
ok then, carry on!
On or Off author is a guy?
No idea, but I think "Mahiro" is a guy's name, at least, isn't it?
Wait, scratch that. I just googled it for the heck of it and found, "Incredible awesome karate girl 'Mahiro Takano' 11 years old", lol!
Why is A1's name associated with this when their name didn't appear on the cover for the manga?
