The original demon. Extremely powerful. He does not die unless decapitated and regenerates infinitely as long as his head remains attached.

A user of Thunder Breathing. An impatient tsundere type with a classic 'hurry, hurry!' personality. He grumbles constantly but takes care of everyone, reaching his peak tension when someone is in a rush for the restroom.

A user of Wind Breathing. A stoic 'yes-man' who silently keeps to his post. He doesn't stand out much, but his absence is felt; he's the most comfortable presence among friends.

Miyo's disciple and a user of Flame Breathing.

A user of Flame Breathing. A chic truth-bomber who hates bothersome things. She looks at the male members with disdain when they act like idiots, but she's the type to secretly watch over everyone from behind.

A user of Insect Breathing. An emotional reaction king and mood maker who reacts with a loud 'Ooh!' to the smallest things. He is full of affection and is the first to cry or laugh at his comrades' stories.

A user of Flower Breathing. A sweet observer whose kindness is evident in her voice. She catches the fine details of emotions others miss and offers comfort, acting as the team's official healer.

A user of Beast Breathing. An over-enthusiastic man of passion whose default response is 'Yes! Understood!' He is a straight-laced guy who sometimes burns with passion in the wrong direction due to his innocence.

The youngest and the definition of pure innocence. He is the ultimate klutz. He falls for his older teammates' pranks easily and has such good reactions that they can't help but tease him. He has a 'cute' personality.
