Miss Ninomiya Hinako, chief disciplinarian at Furinkan High School, had a unique technique for dealing with delinquents.
As a little girl, she had been weak and sickly, suffering from an exceptionally poor constitution. One day while she had been lying in her hospital bed, Happosai appeared at the window and offered to make her well.
She accepted, and over the course of the next few weeks, Happosai taught her various exercises to alter her metabolism, as well as a supplementary technique designed to work with her altered metabolism to draw upon the fighting spirit of others to make up for her own lack of energy.
It had been Happosai's hope to use young Ninomiya to suck the energy from anyone who tried to interfere with his frequent attempts to acquire women's underwear from their owners, but after a time, the two of them finally went their separate ways, and Ninomiya Hinako all but forgot about Happosai.
She moved on into a career in school discipline, where she used her Happo-5-Yen-Satsu technique to drain delinquents of their fighting spirit before they had a chance to get out of hand.

It wasn't until years after parting from Happosai that Miss Hinako discovered the odd side affect of her altered metabolism. Her body stopped growing when she was about eight years old. From that point on, the only way she could attain a body reflecting her true age was by using the Happo-5-Yen-Satsu technique to drain someone's energy.
Remaining stuck most of the time in an eight-year-old body had also had an unusual effect on her mental state. Despite her present age of twenty-four, Miss Hinako often behaved in a frivolous, child-like manner--especially while in child form, though occasionally also as an adult.
On the other hand, she often displayed unusual wisdom and maturity, both appropriate to her adult form, but seeming odd coming from an eight-year-old.

At that very moment, Miss Hinako was in child- form, dressed in her usual yellow, tube-like garment--clothing which was obviously oversized for her, but would fit with almost embarrassing snugness to her curvaceous adult form.
(Nearly all of Miss Hinako's wardrobe consisted of clothing that would look decent on a little girl of eight as well as on a stunning beauty of twenty-four. It was a difficulty the woman had to bear, though she had to admit that she was often flattered by the looks she drew in adult form.)
Miss Hinako was skipping down an uncrowded street, taking an occasional lick from a double-dipped triple fudge ice-cream cone (with sprinkles), and humming the ditty the ice-cream truck had been playing, when a tiny old man suddenly zipped through the air in front of her to be embedded headfirst into a telephone pole.

"We have big puffy faces so that we can do this!" With that he applied some shape-shifting magic to his lips, used his two hands to pull at the sides, and stretch out his lips so they were probably as wide as the grin on an orca.
  "EEEEEEEEEKKK!!!" Claris shrieked, leaping from her seat and darting out of the diningroom faster than a speeding lightning bolt.
  Uncle Jackson poked his head through the door, saw NiGHTS squeezing his face back together, and asked politely "Could you do that again?"

  "But Daddy, I don't understa--"
  "It is our way of life! It has been our way of settling who is superior, for centuries!" he yelled back at her.
Kathren resisted the instinct to cringe in terror and begin to cry. Instead she stood tall and looked her father in the face.
"If you believe in a different method of peace other than the one true method, our method, then you, in reality, are not a human being."
  "Fine!" she lashed back. She balled up a sphere of blue magic energy and swept it over herself. In an instant she grew over a foot taller, her hair grew longer and wavier, her eyes became larger and filled with glitter, her nose and ears disappeared and her face became rounded.
"Then I am a Nightmaren. Then I am your enemy."
She stormed out of the study, leaving the door wide open behind her.
