Оокамі Рьоко

The protagonist who is fierce, like a wolf, and flat-chested, fights thugs using special Neko Neko Knuckles developed by Majolica. She tends to put up a strong and fierce front to disguise her inside nature, where she is a bit more kind and frightened of certain things. Although generally hostile about Ryōshi's wimpiness, she soon accepts him as someone who can watch her back in fights. It should be noted that Ōkami-san's character fits into the tsundere category for anime idioms.

She is a close friend of Ringo Akai and is based on the wolf from the fairytale Little Red Riding Hood and others, though on several occasions she is shown to be very different from her base character; she mostly tries to act and be like the wolf, "wearing a wolf's clothing".
