SUMMER
Summer gave a small 'oh' to the answer and waited for Katsurou to get his luggage so that they could go to their respective dorm. Like her sword, her stuff was sealed away in separate cards, which meant all she had on her person was a messenger bag, a few snacks, her porn book, and a deck of cards with pictures of the items it held. Frankly, it made things a lot easier for herself.
She picked up her own copy of the key and walked alongside the Oni. Summer had thought that he was quite strong just from being able to hold the club with one hand, though with the club and the giant luggage he was hauling around, his strength was very impressive. A gale that a bird like her would have to work hard if she ever wanted to best it! Even Cain would have to work hard to beat this guy strengthwise!
When the two of them walked in to their new dorm, she claimed another bed off to the side. It was a bit high off the ground; perfect to hide her stash! She took out the deck of cards from her bag and shuffled through it quickly, finding the card that sealed her special books. Though, when Katsurou mentioned that changing would be awkward, she giggled.
"I did not think you would be shy, Katsurou~" She teased, licking the corner of the card only once before tossing it onto her newly claimed bed. Soon enough, four large boxes appeared in a small flash of light.
It was obvious by her reaction that Summer would have absolutely no problem changing in front of Katsurou or her other roommates.
CAIN
He had grabbed his own key and walked to his respective dorm. Cain knew he had to share with three other people, and frankly, he wasn't concerned. In their world, men and women were considered equal. So, they did not separate men and women in anything. Competitions, Hot Springs, changing rooms, nothing. Everything was coed, so Cain was desensitized to breasts, vaginas, butts, and penises. He had seen everything in all shapes and sizes as did Summer.
Though the question remained was how his roommates would react to Cain (instinctively) changing in front of them without warning. It was part of his and Summer's culture... And humans did have a history of not accepting those that did not understand the societal norms.
He sighed, taking out his own deck of cards from his bag and claimed his bed. At least from there he could unseal his belongings while waiting for his other roommates to arrive.
