Don't ask me how a 15-year-old boy can be a lieutenant. If Seto Kaiba can be a company owner by grade 10, I think Anstice can be a lieutenant. D:
I believe the name is pronounced "AHNS-tess".
He's special cause he can regenerate.
His name means something along the lines of "ressurrection", which is close enough. Don't know if I'll get tired of this storyline before its even drawn so...
