"Turning my body into fire? Can I be called a human again after that?" That was the first question that Alex had in his mind. Well, considering his Spirits like the wraith or others. He also knew that there might be another humanoid creature he might meet in the future. Sherry might even turn to a human in the future...probably. Even so, leaving his original race just for strength was a matter that he needs to rethink again and again. Even with a cool dragon or phoenix like race, he still needs to think about it before he decides.
[You do not need to worry about that, Host. It will not change your race or something. Your body and race still that of humans, but you can change your fleshly body to fire for a period of time. Take the heart, for example. If someone stabs you at your core. You can change the shape of your heart for a bit by turning it to a fire, and it will return to its original shape after a while. With that, you can avoid death]
