Hi there! First of all, thank you so much for writing to us.

Some of the mods are actually familiar with Ryoji, so I understand where you are coming from. However, Thanatos is an established character in the Percy Jackson universe (see wiki page), so to have Ryoji be Thanatos is a little difficult, while having him be a demigod with Nyx as his godly parent will work.

PS I'm so glad that you are excited! I do however want to let you know that we received a Ryoji reserve today. I'm very sorry about that! But if you're interested maybe in applying as someone else you are more then welcome to. Again, thank you for the interest!
