Author's note: I finally got around to typing this up. Isumi and Satsuki finally talk face to face, and some of Isumi's past is finally revealed. I do not own any characters from Ika Musume.


"The Invasion Grows"

By: pyrotornado

Chapter 7

Will you explain?

"As I said before, saru…" Same Musume said as she munched on a turkey leg. "My name is Satsuki Mendere, and I'm a Shark-type Ocean Walker, saru." She casually introduced herself before the family she had only two days ago attacked. They had arrived just a few hours after Cindy had called the house, mostly because Isumi resisted being dragged through the streets across town, and finally reached the lab. Satsuki had already devoured most of the food that had been prepared for them, so Isumi and the Aizawa's had to make do with crackers and tea. Isumi shook like a leaf in the wind as she sat in front of the entire family, while Erika huddled behind her.

"Th-that's fascinating, geso…." She stuttered. "B-B-but why did you suddenly attack our family, geso?" Satsuki glared at her as she took another large bite out of the turkey leg, which caused Ika Musume to flinch.

"Those…" Satsuki pointed at the blue bracelets wrapped around Isumi's wrists. "Everything I fought for was for those bracelets." Isumi stared down at the jewelry.

"Isumi's bracelets?" Eiko questioned. "Ah, those things that change her weight around at will, right?" Cindy, who had stayed to witness the interview, perked her ears up.

"What's this," She inquisitioned. "Some unknown alien technology that the Ika-Seijin brought with her? What is it?" She crawled over to Eiko, eyes beaming.

"They change the wearer's weight around at will, making them lighter than a feather or heavier than a ship with a twist of the dial, saru…" Satsuki explained. "Invented by Dr. Unzen Kanabe, saru…" Cindy dropped her notepad.

"That's right," She exclaimed. "You mentioned Dr. Kanabe before. So you were talking about Unzen Kanabe after all!" She dropped to her knees in shock.

"Um…Cindy-san?" Chizuru waved her hand in front of her face. "Who is Dr. Kanabe?"

"Unzen Kanabe was an extraordinarily gifted scientist who graduated from MIT just like us, except he did so several years ago," Cindy explained. "They say he was one of the youngest graduates of the century..." She began to type something on her tablet. "At age 14 he enrolled, and at age 16 he graduated with a master's degree in…marine biology?" She widened her eyes in surprise. "His most famous accomplishments included improvements to diving equipment, ocean friendly radar systems, and enzymes designed to eat oil that spills near drilling sites…" She turned the tablet so that everyone could see. On the screen was a young boy in a lab coat standing in front of an aquarium tank. He was wearing thick glasses, had unkempt black hair, and a worn seashell pinned to his coat.

"He's so young," Chizuru mentioned. "Is he really such an amazing person?"

"This is a picture from twenty-five years ago," Cindy sighed. "The aquarium you see here was what he spent most of his first bit of grant money on…" She started looking for more recent picture. "That's one of the reasons I became surprised when the Shark-alien mentioned him before, my family used to take me there as a child…" She turned the tablet towards them again. This time it showed a man in his twenties, he had thinner glasses, another lab coat, and the same seashell pinned to his shirt. "This is the last known photo of him, taken from his driving license…" Isumi's eyes widened, but she didn't say anything. "About fifteen years ago, Dr. Kanabe went missing on an oceanic expedition. His ship washed ashore on a small island about a hundred miles off the coast of Nagasaki, where he had born and raised. The ship was intact, but Dr. Kanabe and all of his current research had been recorded missing."

"What had he been researching?" Eiko asked.

Cindy closed her tablet. "Like myself and the others here, Unzen Kanabe was a dreamer." She announced. "He openly expressed his beliefs and theories, though most didn't care to listen to anything but his grounded research, much like us." She closed her eyes. "No one cared about his dreams, only about his grades, his studies, his research, and how to look in front of someone, how to speak properly, and…"

"Um…Cindy-san?" Chizuru waved to get her attention. "We're discussing Dr. Kanabe, remember?"

"Oh right…" Cindy blushed, realizing she had been describing her own experiences. "For the most part, I was telling the truth," Cindy coughed. "Unzen Kanabe, although an outright genius, was a tad eccentric towards others. He openly expressed his beliefs in intelligent underwater life…" At that moment, everyone turned to the three fish-hybrids in the room.

"What, geso?" Isumi started to nervously munch on a cracker.

Eiko shook her head. "Seems like a more likely scenario than Cindy's alien research…" Chizuru and Sanae both nodded.

"That's right!" Sanae exclaimed. "This proves that Ika-chan isn't some gross alien!"

"How does it prove anything!" Cindy retaliated. "And don't call aliens gross!" She and Sanae started staring daggers at each other.

"Is now really the time for this, geso?" Isumi spoke up.

"Let'm fight it out, saru…" Satsuki gnawed on the bone of the turkey leg. "Alien or not, we were both born in the ocean, so that makes us residents of this planet, right saru?" She leered at Isumi, who proceed to shake again. Finally, Chizuru broke up the fight, allowing Eiko to speak.

"So…this Dr. Kanabe dedicated his whole life to learning more about the ocean in order to find….these guys?" She asked. Cindy thought for a moment.

"Hmm…" She mumbled. "I'm not sure…" Satsuki tossed the bone, picked clean, onto her plate.

"Back when I was out hunting for food back in the ocean, I came across an abandoned hut, saru…" She yawned. "I thought maybe the last Ocean-Walker to live there had left some food lying around so I checked it out, saru…" Satsuki grinned at Isumi's face. "As it turned out, the last one to live there had been the Ocean-Walker's pariah, Mirabelle Kanabe, wife to the human, Unzen Kanabe…" Isumi started to tear up.

"Ika-chan?" Sanae looked at Isumi's face.

"When I rummaged through the rubble, I found some of the good doctor's notes, which detailed his research and describes the weapons he designed to protect his wife from persecution, saru…"

"Persecution?" Eiko asked. "Why would they persecute her? What did she do exactly?"

Satsuki shook her head. "Humans aren't that accepted in the Ocean-Walker community, but Mirabelle fell in love with one, saru. Every time an Ocean-Walker has come to dry land before, a great panic would ensue and the humans would end up killing it like a monster, saru…" Satsuki leaned back in her chair. "That's the story we're told as pups, anyway saru…"

"So it was like a racial issue, huh?" Cindy mumbled. "Like when two people of different races fall in love in a community of only one race…"

"But…that idea is so old fashioned!" Sanae defended, scooting closer to Isumi. "I don't care if Ika-chan's a fish or not, I love her all the same!" She glomped onto Isumi's arm.

"Geh!" Isumi used her tentacles to push Sanae back to her seat. "Stop doing that, geso!" Satsuki chuckled.

"Regardless of one's personal beliefs," She continued. "The Ocean-Walker community shunned Mirabelle after she got married, saru." She turned her gaze to the Ika sisters. "When word got around that they were trying to have children, they got violent, saru…" Isumi looked down, quivering.

"Onee-sama…" Erika clung to Isumi's dress. Isumi put her hand on Erika's head, trying to force a smile.

"I'm not sure what happened after that, saru…" Satsuki shrugged. "Most of the pages of his journal were too damaged by the water after that, saru. The only other thing I found was a couple of drawings depicting those bracelets and what they were designed for…to give an Ocean-Walker unbeatable power, saru!" She grinned. "I guess the good doctor did alright, considering his daughter used them to take down a shark like me, saru…" She announced sarcastically.

"So, you really are the daughter of Dr. Kanabe?" Eiko asked. Isumi shook her head.

"I…don't really remember dad's face too well," she admitted. "By the time I was able to swim alone, he was already gone, geso. Mom took care of me and my little sisters by herself, geso." She started stroking Erika's head. "One day…" She tried to start, but the words got stopped in her throat.

"It's alright," Chizuru petted Isumi with her good hand. "I can roughly guess what happened, given Satsuki-san's information." She turned her gaze to Same Musume. "Thank you for telling us, Satsuki-san…"

"Keh…" Satsuki scratched her head. "I don't really care anymore, though saru…" She looked around the lab. "Even though this place is a bit strange, the food I've been given is amazing, saru!" She smiled wide at the memory of her feast from before. "Yosh, I've decided, saru!" She slapped her leg as she stood up. "I'm gonna live here from now on, saru!"

"Eh!" Isumi gaped. "Why don't you go back to the ocean, geso?"

"Why not?" Satsuki grinned. "All I ever cared about was how to make landfall without being killed by the humans, and I've already achieved that here, saru!"

"But…" Isumi was pushed aside by Cindy.

"Oh, Same-Seijin!" Cindy exclaimed. "You have no idea how happy I am to here you say that!" She pulled out a clipboard. "We have so many things to research and record, I don't even know where to start!"

"Uh…" Satsuki scratched her head. "Sure, doc. But first can I have a place to sleep, preferably someplace close to water, saru…" Cindy grabbed Satsuki by the hand and pulled her towards the door.

"Yes, yes," She replied. "We've had the perfect place already set up for the Ika-Seijin in case she ever decided to join us, but I'm sure we can modify it just for you!" Cindy was in her own little world as she pulled Satsuki out of the room, leaving their guests behind.

"Looks like you're finally off of Cindy's hook, Isumi," Eiko teased.

"Probably because she's part human," Chizuru smiled. "Isn't it wonderful that we now know your family name, Isumi-san?" Isumi, who was still reeling from Satsuki's hasty exit, shook her head.

"Huh?"

"Satsuki told us that you and Erika are Unzen Kanabe's daughters," Eiko explained. "That means that your full names are Isumi Kanabe and Erika Kanabe…" She gave them a deadpanned grin. "Who would have thought that under all those squid powers, like lighting up like a lamp and spitting out squid ink, you had some human blood in you, too!"

"Huh?" Isumi cocked her head to the side in confusion. "What do you mean? I don't have any human blood, geso…" Eiko shook her head.

"Your father is a human, so that means that you are part human!" She explained exasperatedly. "Don't you even realize how babies are made?"

"Of course, degeso!" Isumi retaliated. "Mommy taught me all about babies, geso!" Everyone waited to hear her explanation. "A mother squid lays her eggs, and if a mother squid and a daddy squid love each other enough, babies hatch from the eggs in response to their feelings, geso!" Several moments of stunned silence passed by.

"Wow, geso!" Erika cheered. "That's amazing, oneesama!"

'There is no way she's that stupid…' Eiko shook her head.

"That's so wonderful, Ika-chan!" Sanae lunged from her chair. "When we live together in the future, let's fill the entire house with our feelings!" Isumi's tentacles slammed Sanae into the table.

"Any baby of yours would probably be just as crazy as you, geso!" Isumi angrily got up and headed for the door.

"Wait up, oneesama!" Erika chased after her.

Eiko shook her head as she helped Sanae off the floor. "Don't you think we should explain it to them properly, Aneki?" Chizuru shook her head.

"That innocence is just like her, isn't it?" She smiled. "And for the most part, her explanation wasn't completely wrong…"

"I guess not…" Eiko sighed as she carried the unconscious, smiling Sanae out of the room, with Chizuru close behind.


How's that for a surprise? The incredible Squid Girl is actually part human! But more surprising than that is how mellow Same Musume became when she was fed. I guess the way to a shark's heart is through it's stomach after all.

By the way, I'm tossing an idea around creating a spinoff fanfiction called "Kanabe's Journal", which details the years that Unzen Kanabe went missing. I don't want this fanfiction to turn into some sappy drama like so many others before it. I already said I wanted to keep this story as lighthearted as the manga, so while Isumi's story will be revealed later on in this one, I'll be working on the love story between Mirabelle and Unzen in a new one. My only concern is that almost every character in it will probably be an Original Character, so I'm not sure it will be allowed in the Ika Musume section.

Please reveiw and IM me for your responses.
