Zack is the cousin of Harley and is the most “moody” of the whole house. Zack’s memories were wiped at the age of 4 after witnessing his parents Death and Time also removed his happy memories he had. Zack doesn’t eat much, but Zack does sleep, he usually sleeps and never wants to get up. Zack is always in a mood swing going from being happy to being sour to people who irritate him, or even sometimes he acts heartless. He doesn’t realize it when he’s like that, he feels alone and left out even by his own house members.
