With an announcement in class.

"Good morning class!" Shizuka greeted everyone once homeroom started that day. "Now, to start today's lecture, as I have been saying, this university is based around teaching monsters how to interact with humans and blend into their society. Which is why, starting today, you will all be taking up club activities!"

"Club activities?" Tsukane asked, his interest piqued.

"In order to gain an even greater understanding of humans, these clubs are based around human made activities, and thus, participation is geared towards deepening your understanding of humans! To transform into humans, one should understand humans!" she lectured.

"Eh, Teach, wouldn't that give you an F then?" one student sniggered.

Shizuka froze, her smile rather fixed as she looked behind herself to see her cat tail swaying behind her, apparently having slipped up with her transformation. 'Well, that's adorable,' Tsukane thought with some mental amusement. He was giving some serious thought to using the Sex Note on Shizuka some more.

Shizuka then proceeded to hiss and scratch at the student who had called out her slip up, making the rest of the class sweat drop. Shizuka then proceeded to act like nothing happened, and told everyone that they would have to participate in at least one club, and shamelessly plugged the Newspaper Club she was the advisor for.

After class, Tsukane and Moka found that there were a lot of advertisements for the club activities going around. "This is incredible!" Moka cheered, before looking at Tsukane. "What club do you think we should join Tsukane?"

"How about the swimming club?" Tsukane asked, making Moka flinch as Tsukane started to explain how swimming was something he was actually good at, before trailing off as realization hit him. "Oh... Right... Vampires, water..." He rubbed the back of his head sheepishly. "Sorry. Forget the swimming club then."

"It's alright Tsukane, I'm glad you remembered what I told you, even if it took a second," Moka smiled. "Maybe that newspaper club!"

"Hold it!" Kurumu said cheerfully, startling them both as she approached. "You shouldn't rule out the swimming club just yet, I have a solution!"

"Wha- Kurumu?" Tsukane asked.

Kurumu grinned at Tsukane and Moka, who gazed at her in confusion. She had a nice and skimpy bikini that she wanted to show Tsukane, and the swimming club was the perfect opportunity for that... Not to mention he'd made her and Moka bisexual now, so... "Just use the Sex Note!" she told them excitedly but quietly. "I bet it could remove that weakness from Moka, and it would count as something sexual if you wrote it was so as to see Moka in a swimsuit!"

Tsukane sputtered slightly, before trying to act like that hadn't been part of the reason he wanted to join that club in the first place, while Moka blushed heavily. "Erm... But, wouldn't that make some students suspicious?" she asked. "They know I'm a vampire... If I were to suddenly be comfortable in the water..."

"A good point. However!" Kurumu grinned, holding up two fingers. "Counterpoint the first! No one actually KNOWS you're a vampire, it's just a prevalent rumor! And counterpoint the second! There are water antidote herbs that can allow vampires to enter water that aren't THAT hard to get, so even if it does get out, you have an explanation for it!"

Moka paused, actually considering the suggestion. "But... Um... Well, I obviously don't have a swimsuit, so..."

"Not a problem either! The school has some for sale! Besides..." Kurumu grinned, leaning close to Moka. "Think of aaaaalllll the sexy babes in bikinis that we'll be able to look at with Tsukane-kun... and you'll be able to get rid of a major weakness in the bargain..."

Moka was now beet red as her imagination ran wild. Tsukane making her and Kurumu bisexual was definitely messing with her perverted side.
