Master

Master (マスター, Masutā) is the owner and proprietor of Leo's favorite Diannes Diner and Vivian's father.

Appearance
A tall, grim-faced man dressed like a typical Diner-chef with casual clothes under a white apron and short chef's hat.

Personality
Despite his gruff exterior, he's kind enough to allow Leo to wash dishes in exchange for a meal the boy otherwise couldn't afford.

He clearly loves his daughter, as he purposefully used his body to sheltered her from the debris when his diner was destroyed during the Yog-Gphot's rampage. He also shows he trusts Leo enough with Vivian's safety when he urges him to escape with her.

Like Vivian, he has clearly adapted to life in Jerusalem's Lot, as even after his Diner is destroyed he continues to work out of the ruins until it is rebuilt.

Plot
He was seen working with his daughter at his diner, were Leo often comes. Seeing Leo not having money and only drinking free coffee, he gave a hamburger to Vivian to feed Leo. Later when his diner was destroyed by the demigod, he was seen passed out while protecting his daughter from the fallen rubble.

Power & Abilities
As ordinary human, he doesn't posses any extraordinary abilities or power.
