"What do you want!!", yelled Kawakami to Ren as she tried to close the door of the closet in his face.

"I just want to help you...", he replied as he desperately tried to get her attention.

"And how ?", asked Kawakami skeptical of him.

"Ehh...with this...", said Ren as he then passed through the door a shiny looking dress uniform.

"What the---, how ?, and why you have something like this ?", asked Kawakami surprised at seeing such expensive looking women's garments in the possesion of some teenage student.

"Let's just say i got them from a job...", Ren said as he scratched his hair, "I knew that giving her one of Ann's old armours was the right choice!", whispered Morgana to his ear.

"Well... in that case...", said Kawakami, upon which, she decided to ditch the tattered remains of her skirt and shirt, and put on the new dress that Ren had brought to her.

"So, how does it feels...", asked Ren behind the door.

"I...like it!", exclamed Kawakami looking at herself wearing the dress, which though was a little short in height, still fit her perfectively.

"Well..., shall we return to the gymnasium...?", asked Ren.

"Ooh, yes...", replied Kawakami, upon which, she returned with him to the gymnasium.
