Christine

Christine is part of Eisuke Yamauchi's crew in Five. She's one of his most trusted subordinates, and part of the enforcer group under his command.

In a plan with Nishio and Fukuda, she is designated to go after Masuo Hamada in order to help Eisuke, who's being strongly pressured on the Phantom Thief case. While her unique behavior makes it initially seems like she didn't put any effort into it, her job pays off during the final confrontation.

Christine is extremely quiet and unexpressive, often hiding her face behind a magazine or computer, and just showing her face for a moment to reply to Eisuke's command with a thumbs up, only to immediately hide her face behind that thing again.

Deck
Christine uses a King Tiger Deck - a Deck expanding on "King Tiger Wanghu", with deadly effects that kill off monsters as soon as they are Summoned.

This Deck becomes dangerous against Decks that swarm weak monsters to serve as material for stronger monsters.
