There's no magic, but there might be a dirty trick.

Tenko held Himiko tightly in her grip, still preventing her escape. "Now, Himiko, a technique of Neo-Aikido will allow me to see into your true heart and feelings once I toss you. At that moment, I and everyone else will see your true bravery! I'm looking forward to it!"

"Just listen to me..." Even begging for her dignity was beginning to tire Himiko out. Tenko wasn't listening... Wasn't there some kind of weakpoint Tenko had that the mage could exploit? She could probably try calling her cute or batting her eyelashes, but the fallout from that might be even worse than whatever else was going to happen... "Then, it's come to this, nyeh... I'm sorry, my friend and assistant. It's kill or be killed..." With a serious expression, the mage shouted with rare energy. "Offensive Magic: Severing Spell!"

This spell wasn't really any kind of spell at all: Himiko simply reached out and dug one of her small hands beneath the taut strap of Tenko's bikini top. All it needed was a little bit of extra tension for the whole thing to come apart. Rather than that shoulder strap alone, the entire thing snapped, leaving both panels peeling down and away from her breasts.

Tenko's face went red as she cried out, and she tossed Himiko high into the air to cross her arms in front of her chest, helpless to prevent the garment falling and drifting away as soon as it was no longer kept pressed to her by a body. "Kyaaaah!! Himiko, th-that's way too lewd in front of these drooling males! C-control your urges until we are in private, please!!"

Himiko didn't hear the complaint, obviously. As all three boys watched with jaws dropped in amazement, Himiko's tiny body somersaulted through the air with a wild cry... then landed in the soupy water with a squelching noise, sending a messy splash of green goop splashing onto the pool deck. A cut-out of her body was left in the film on its surface before quickly clouding over. The Ultimate Mage had disappeared.

Shuichi looked at Tenko in horror. "Wh-what the heck?! We've gotta help her!"

"Nonsense!" Tenko shouted back at the offensive male's offensive suggestion. "You'll have to try a bit harder if you want me to uncover myself for your sweaty pleasure! After all... I-I mean, I was a little distracted when I threw her, so I wasn't able to use my Neo-Aikido to tell, but I'm sure Himiko is now happily conducting her magic like a pro, confident in her abilities and happy that she decided to follow her heart!"

"Yeah, Shuichi!" Kokichi agreed, chiding Shuichi with a wagging finger. "Why do you hate magic so much? Why can't you just believe in your friend?!"

"How am I the bad guy here...?!" Shuichi grumbled, moving to the edge of the pool and looking for any trace of Himiko. He couldn't see anything. "Keebo, can you pick up her vital signs?!"

"I... don't have any kind of function like that," the robot admitted sheepishly, wringing his hands. "I recommend seeking the help of a qualified paramedic."

Tenko scoffed once more, still covering her bare chest with one arm as she placed her other hand upon her hip. "Disgraceful men, I'm telling you, there's nothing to worry about! A slimy pool is no match for Himiko's magic prowess, not when she gets serious! Just wait a few seconds more, and you'll see..."

Everyone, even Kokichi, went silent for the moment. Seconds passed.

"D-disgusting men! Simply watch patiently, and you'll see Himiko's... precious, **** form that makes you want to protect it appear before you..." Tenko kept one arm crossed for dignity, but had moved the fingers of her other hand into her teeth, biting them nervously.

Finally, something began to surface.

The martial artist's eyes lit up as she broke into a delighted grin. "See?! I told you everything would be just fine if you... believe in..."

The figure in the pool was face-down, blowing bubbles in the slimy water. It was so coated in green goop, it was hard to recognize, but that tiny body.. had to belong to...

Tenko howled as she ran to the edge of the pool without sparing a thought for her now freely-bouncing boobs. "Himikooooooooo!!!"
