Kazeno watched as the delicate girl tried to break up the fight, her bravery was commendable. However, he wanted to see something interesting today, and having a hot-headed pyrokinetic fight a stripperific Ria would prove to be interesting enough he assumed.
"Pardon me." kazeo said to Sasaki as he grabbed his drink and jumped up.

A few quick airdashes lead him to the hanging lights where he sipped his drink in anticipation for a esper-gladiator showdown. Chi Ni sat next to him, donning a ghostly foam finger and a tiny flag with the white letters that spelled "fight" on them. Kazeno could only hope that she wouldn't do anything stupid like rocking said lights. Which unfortunately, she did to great effect.
"Chi Ni! Stop shaking the lights!" Kazeno yelled, "They aren't even mean to hold my weight!"
"That just mean's you fat~" 

One seconds later, the Duck materialized into Kazeno's hand as he stuffed Chi Ni's mouth with it. A series of (comical) gurgling noises came out of Chi Ni's throat as if she was choking (or the ghostly equivalent). Hopefully that shut her up and he wouldn't be arrested for animal abuse, although the Duck didn't seem to care that much.

"Okay, you two, you heard the lady. You wanna fight? Take it outside! I'll even referee the match for ya."

Kazeno looked down as Chi Ni finally coughed up the duck, he saw one very eccentric-looking teacher standing in between the hot head and the stripper. If he recalled correctly, he was cheering them on not a second ago, Kazeno wondered what gave him a change of heart. A wave of rumors and murmurs followed in the wake of the announcement, even as the teacher (forcibly) led the two outside for their fight.

"Should we go after them?" Chi Ni put down her spiritual foam finger and asked Kazeno who had just stood up.
"Yup." Kazeno stretched his arms, "Time to fly."

With that, Kazeno fell off the handing light and air dashed his way over the heads of students who were all head to the track field.
