Haruto Kazuya

Hearing Haruto's name Kretos first thought was, this guy was a noble? He then dismissed the idea, the way Haruto acted and talked had no indication that he was raised in a noble household. 

"Haruto Kazuya, so Haruto is your given name and Kazuya is your family name, correct?" 

"Yeah, that's right," Haruto answered as he cleaned his plate. 

"I'm Kretos, I have no family name if I do have one I can't remember it." Haruto looked at Kretos and started assessing him. 

"Do you have amnesia?" 

"Is that what you call this, where I can't remember anything from my past." Hearing Kretos's response Haruto took out his box of cigarettes and gave one to Kretos.
