A thing: what if Naki takes Miza’s surname because he doesn’t have one?

Can this be canon?

“I now present, Miza and Naki Kusakari,” Kaneki announces as he closes the ceremony.

“Kusakari?” Ayato frowns.

“Naki doesn’t have last name,” Hinami hisses back.

“Hmmph. Well, I think Naki Kusakari sounds nice,” Ayato says stiffly to hide the burning in his eyes. 

“You may now kiss,” Kaneki adds. 

Naki’s face sparkles as he takes Miza in his arms and kisses her with all the passion he has ever felt.
