Before a chapter with new characters, I shall post "intro" showing how they officially look like. Bear in mind their appearance in this story is slightly altered. I hope this will help you to enjoy the book more.

I will use official pictures and try to avoid fan-arts. I have nothing against fan-arts, but I would like to avoid any potential trouble.
