According to my deductions, Yotsuba company is indeed a reference to the green-haired 404-girl Yotsuba. Then again, if Yotsuba company was a reference, they would not be so obvious about it by making their logo similar to a four-leaf clover. Even more obvious is the fact that the clover of Yotsuba company is in direct opposite stance to the clover of Yotsuba girl, suggesting that, indeed, they are the Anti-Yotsuba, showing that instead of bringing lulz, they plan on destroying lulz, but if that was their intention. Even more evident is the fact that their logo has the color red, which implies power, making it seem that they feel they control the power to destroy lulz.

Therefore, it is my conclusion that Yotsuba company is indeed Kira.
