New doujinshii circle, "Raw" website

It's her new site after she closed her Nitro Koutetsu one. Has anyone been able to access it? The site is here: Raw.

Apparently, you can't access the site on its own. You have to answer a list of questions (riddles?), and when you solve them, you fill it in after the url like this: day.jakou.com/●●●●●/ (replacing '●' with letters of the answer). Then the site opens.

The questions are in Japanese, so I can't read or solve them, but does anyone here know? Here they are:

①ずれていたのは何番ピン？　（数1文字） 1 letter
②海老塚中出身者の人数　（数1文字） 1 letter
③この世界を表す例の英単語（略語）　（英3文字） 3 letters
全部で5文字

I see. Although this post is a little old, I wonder if that's why I was recently still getting a dead link.

Thank-you for posting this, it goes some way to alleviating the frustration of not knowing. :\
