Known as Wardog 2. Despite of her gentle and harmless appearance, she can become very hostile to anyone who dares to harm Hibiki. Not only she's overprotective of Wardog 1, Yuzuka is also possessive and very loyal to the point that she'd follow Hibiki even in death.

Though she can be violent if you accidentally see her naked, as long as you call her gorgeous to the point that you can't forget about her, Yuzuka will forgive you.

Warning! Make sure to say you're awake or fine if Yuzuka knocks on the door. She has the tendency of breaking down any doors with an axe if she doesn't hear a response.
