Futaba Kanzaki

is Hajime Kanzaki's niece and Mugen Kanzaki's granddaughter.

Appearance
Futaba is a young girl just a bit taller than Beel, with blonde hair worn in pigtails and brown eyes. She wears dark tights and white shoes along with a light, multi-striped dress. Futaba also wears a hoodie to match her outfit.

Personality
She is just as spoiled as Beel and has the same fighting style (kicking) and bad temper as her uncle Hajime. Futaba likes to play with her uncle but not vice-versa, as Kanzaki is frequently always ignoring her or pretending she doesn't exist. Still, she plays tricks on Hajime in order to get his attention.

She dislikes to be with her grandfather who tries every thing to make her like him.

Saint Saint X'mas Arc
Sometime before the holidays, Futaba goes to the local shopping district where she meets "Santa Claus".

Later, she looks at a girl magazine and searches through the catalogs, eventually finding an item that she likes. Futaba tells Kanzaki to go tell Santa Claus that she wants the item specifically on Christmas Day and even threatens to kill him if he screws up with the gifts. Suddenly, she is instead told that Santa Claus was killed a month before after he ran into a dump truck, horrifying Futaba. However, she recalls meeting the holiday figure earlier that day at the local shopping district but is told that it was an imposter; upon hearing this, she becomes angered at the thought that such a person could be underestimating her.

Futaba goes outside her house and draws on the asphalt with a piece of chalk, moping about Santa Claus being dead. She eventually sees Yuka pass by and asks her whether it is true; to her delight, she hears that Santa Claus is still alive. Her excitement peaks when she discovers that the "real" Santa Claus will even be coming to Yuka's high school; hearing that, she asks if she can meet him, which Yuka promises her that she will.

On Christmas Eve, Kanzaki and Yuka return together where the latter tells Futaba that she was unable to let her meet Santa Claus; despite this turn out, the young child is perfectly fine about it and instead asks to not be licked any further. However, Yuka decides to grant Futaba's wishes for her.

Futaba holds her hand and together with Kanzaki, whose pants are grabbed by Futaba herself, they go to purchase Futaba's gift from the local shopping district; despite their concerns, she simply tells them to just be quiet and go with her.

Powers & Abilities
She seems to have the same bad temper and fighting style (kicking) as her uncle Hajime Kanzaki.

Yuka Hanazawa
Futaba and Yuka seems to get along pretty well and she immediately recognized her as 'Paa-ko'. The first time they met each other was when she was looking for Hajime and she ran into Yuka's group. When Yuka saw how bratty her personality is, she deemed it cute and it made her want to hug her. Then they turned looking for Hajime into a competition, resulting into them geting lost and kidnapped.
