Unknown New World:Next Heaven:Chapter 6:New semester in class Next Heaven (Io)

Alice and Kizuna were led to the girls dorm after the tour and Io was brought to the old boy's dorm which is currently occupied by one of the teacher's family.

"So this is the old boy's dorm,it's pretty big" Io knocked on the door and waited a bit........after a while, someone answered the door,
"Welcome to your new dor......why are you here?" The person who answered
the door was the one who sent Io the invitation letter,
"You,just as always your chest is still big!" Io laughed while probably sexually
harassing a girl.The girl shut the door without letting Io in.
"How rude...." Io sighed,"Sorry!but I'll be coming in without permission!" Io 
kicked the door causing the door to break like an explosive was put beside it.
"Why did you break the main door!!!!" The girl exclaimed.
"It's your fault for shutting the door in front of me" Io replied,
"It's true that its my fault,I'll apologize this time, Io-kun" The girl swallowed her pride
and apologized.
"I'll forgive you this time,Nei" Io grinned,
"How did you know my name!Are you an esper!Mind reader?" The girl asked.
"So you're the type of person who puts their name on their underwear, in your case
its in big characters (利理'ネイ)(Ririka,Nei)" Io smiled at Nei while staring at her chest,
"Eh?..........Nooooooooooo" Nei finally realized that her uniform finally gave up and 
exposed her chest,
"awawwawawawawawa.......I'll kill you,I'll kill you!!!" Nei drew out a want with a crystal tip and casted"Collosal Magic:Spear of Indra!" Nei casted a giant trident made out of ice covered with electricity.
"Hmmm....Interesting!Amazing! Come at me with all you've got!" Io prepared his
fist and punched the trident causing it to explode and destroyed half of theboy's dorm.
"Impossible,he broke my Colosal Magic in one hit.Damn you!!!!!Io-kun!!!!!" Nei exclaimed
"Nice to meet you,Nei-sensei!(Teacher)" Io replied to Nei.
"I'll make sure you will fail all your classes!" Nei again exclaimed,
"What a great way to start the semester" Io laughed
