Yume Tsubakuro (燕結芽 Tsubakuro Yume) is the fourth-seat member of the Origami Family Elite Guard and an alumna of Ayanokouji Martial Arts School. Yume shows a childish personality appropriate for her age and is a battle maniac, flipping like a switch into a mode where she becomes unstoppable. Because of this, she is treated with utmost care by those around her, and is often forbidden from joining any operations, which leaves her dissatisfied. Despite this, she isn't evil, she doesn't kill, and mostly wants to live her life to fullest, fighting great battles and making people remember her existence and her greatness.
