Tutotiral on how to register as a You supporter
Thanks to 行くぜ！怪盗Ｎａｏｙｕｋｉ @ H!O
Send in a mail to this address with the content "このまま送信ください。"
Then they will send you an email in response with the link to the registration page.
Just choose 東京 for location.
This is how the page will look like with translation.
Your login name will be your email address.
That's all you need to do.
Hope you guys support Kikka's solo works.
Feel free to spread this out to your friends. The more people we have the more UFA will do for her.
