At the research building, Tohka and Shido enter it, only to meet with a woman with long black hair, in a white school uniform and white leggings. She said to them, "Excuse me, but what can I do for you?"

Tohka bowed and said, "Yes, Miss. My name's Tohka Yatogami. I happen to be friends with Ginti Okette. I was wonder if he was here in this place."

The woman said, "Not that I'm sure of. But if I know of a man, please let me know."

"Uh, I was asking you if he was here."

"No. But I have heard about you, Miss Yatogami."

She sat up and said, "My name's Oboro Tsukimigusa, and I am head chemist of the Research Lab."

Shido said, "So, you're one of them?"

Tohka replied, "Ignore my boyfriend. He's just agitated over this. Plus, I bet he's a fan of Anode and Cathode Electronica…"

He winced, "T-T-T-Tohka! Please…"

Oboro said, "Yes, I'm aware of that."

"How come you talk like a robot?" Shido asked.

Tohka said, "Yeah… and what's this Rhombus Research?"

Oboro stated, "All data required for the Tokioka Rhombus Research Inc. is strictly classified. But strictly confidentially, it is none of your concern, Tohka Yatogami."

Tohka prepared, as Oboro adjusted his sleeves, "But you really don't need to know."

Tohka asked, "Where's Ginti?"

Oboro said, "Oh, you don't want to know. Besides, I wouldn't sully my hands onto you…"

She undid her red tie and unbuttoned her shirt to halfway, revealing a white rhombus diamond on her chest. She said, "Naturally, I have the power to do so."

She wore white gloves and added, "But I can't sully hands on my gem… or yours, Yatogami."

Tohka growled, as she prepared to strike. But Oboro pressed her gem and said, "Halt!"

Tohka stood in attention, as Shido gasped, "TOHKA!"

He cried, "What have you done to her?"

Oboro said, "It's nothing, really… except she's one of us… She's our Rhombloid, and she's designed to perfect our world. But you know too little, so we'll have to take you in."

Shido prepared to fight her, as he said, "I don't care if you control me… And I don't believe you!"

Oboro ordered Tohka to reveal herself. She unbuttoned her shirt and showed a dark blue gem on her chest. He gasped, but was angry, "YOU MONSTER! GIRL OR NO GIRL, I'LL KILL YOU!"

Tohka grabbed his arms and threw him into the wall. Her face showed no emotion, as Oboro said, "Not quite… You can't kill me. But we can't kill you, though. We're only observing, and seeing who joins our collective."

Tohka bowed to her and said, "Master. I have bested my boyfriend."

Oboro said, "Excellent. Have him sedated… with your thing… and I'll inform the head of research to begin operation on Shido."

Tohka said, as she turned to Shido, "Yes, master."

She walked doll-like and robotic, as Shido was getting up. He cried, "Tohka! FIGHT IT! You're being controlled!"

Tohka slammed her hands beside Shido, blocking his attempts to escape. She said, as she was about to pucker her lips, "Kiss me."

She kissed him on the lips, and Shido suddenly started to limp a bit, from Tohka's sexual charm. Oboro nodded, as she said, "Good. Another subject has been recruited. I shall inform the staff. Make sure he's unconscious, before we could begin. I shall return."

She left to find the research team, to take Shido away, while Tohka was still kissing him. Shido was growing weak, limp and wobbly from his legs. He was about to pass out, until…

SMASH!
A figure smashed through the window and called out, "GET OFF OF HIM, YOU BITCH!"

Tohka stopped, as Oboro was shocked. She asked, "Who are you?"

Tohka beeped, "Imposter."

The woman who entered through the window… was the real Tohka Yatogami.

"Sorry, I'm late, Shido. I heard a yell, and arrived in this city, but I spotted you, with this hussy of a robot imposter."

Tohka 2 said, "Wrong answer. I am Tohka Yatogami. This man is my boyfriend."

Oboro asked, "Huh? You're Tohka Yatogami…"

"SILENCE!" Tohka roared, "How the hell did you get my likeness, you bitch?"

Oboro said, "You said something about Ginti… or should we say our android decoy? She was installed everything about you, personality and all, and we even learned of a rogue robot group called KEION Bu. All the files are there. You, Ginti, the Electronica Sisters, and a Lan Hikari. All we want is answers, since you and your friends know too much about the KEION Bu. We sent her, your android double, to find and inform Lan Hikari, and ask him many questions. But instead, we run into him, your boyfriend."

Tohka whispered, as her robot double said, "And I have told him everything, yet he didn't believe me. Too bad. My boyfriend needs adventure…"

She leaned to him, as Tohka shouted, "YOU GET YOUR HANDS OF HIM, ROBO-TOHKA! Shido's my man!"

"Says you." Tohka Robot said, "You want him, kill me for it."

Tohka smiled, holding her sword up, "I be glad to."

Oboro ordered, "Restrain her, Tohka-Bot!"

Tohka Robot said, as she dashed forward, "Yes, master, I obe-."

SLASH!
Tohka decapitated her robot double, and sighed in disappointment, "Jesus Christ… That was anti-climactic."

She put the sword away, Oboro said, walking to her, "Impressive… No one in their right mind would destroy a Rhombloid, especially a clone of you, Yatogami."

Tohka said, "Shut it, Robo-Slut!"

Oboro stated, "Cut me, if you like."

She swung her sword at her, but nicked her arm. She was lightly bleeding, as Tohka gasped, "What? Another controlled robot slave?"

Oboro said, "We're not all robots, dear."

Tohka stepped back and moaned, "No… What are you?"

"Like I said… We're one of the scientists in charge of the project. We are to increase the population of Rhombloids, after the recent people that disappeared. Namely those that perished: Ritsu Tainaka, Tory Hikawa, Sonia Strumm, Yuno Gasai, Maylu Sakurai, Geo Stelar, Jun Suzuki, Luna Platz…"

"Those were the names of the people that fell to the KEION Bu; most of them were slaves, only to turn on the faction… and Lan was devastated, seeing his friends die… like that…"

"I see. MegaStar, perchance?"

"Yes."

Shido snapped out of his trance, as Tohka said to Oboro, "Listen well, you jerk. Whatever you're doing to them, and whatever you're planning on doing to Lan Hikari, Shido and I will stop you!"

Oboro said, "Is that so?"

Shido kneeled up and moaned, "Ungh… What happened?"

He asked, "Tohka? Why did you side with the enemy?"

Tohka said, "This bitch used a robot of me, to fool you!"

Shido looked down and gasped, seeing the robot's severed head. Shido cringed, "My goodness… No wonder. Wait, where were you, then?"

"I saw you with that robot girlfriend. I hid in secrecy, and found the place where Ginti is held. She can act like me and perform like me, but she has no weaponry to wield."

"You're right. The real Tohka Yatogami, you, would never fight unarmed."

"That's why your Rhombloids are pathetic in combat."

Oboro said, "We'll see about that. You can fight androids with gems for cells, but can you fight a human that can withstand power?"

Tohka barked, "Bring it, you upscale ruffian!"

Oboro fought Tohka, only she would be struck in the waist with her sword. She slashed her down, moaning in pain. She kicked her in the gut, as Oboro grabbed her legs, and slammed her elbow onto the knee. Shido tackled her down, but she kicked him off her body, with a flying kick. Shido landed on one knee, as Tohka swung her sword and slashed at Oboro's chest, nearly cutting her deep. Oboro did a backflip, but Shido grabbed her in the waist, from behind. He threw her down, as Tohka said, "Good work!"

Oboro got up and moaned, "Darn. That hurt."

Tohka said, "What now? Never thought we'd fight, side-by-side, before…"

Shido said, "Don't worry, Tohka. I have a contingency plan, to stop this dastardly girl."

Shido pulled out a sword, similar to Tohka's. He held the sword up, as he said, "Time you shall be slashed to bits!"

Tohka smiled, "I see you kept it, didn't you."

Shido said, "Oh, yes. Now, let's finish this fool!"

Oboro stated, as she pressed her gem, "Not quite…"

She stood in attention and removed her white blazer. She threw it to the floor and said, "I'm about to give you a dirty treatment. I only exfoliate lewdness, but you two are thorns on our side."
Tohka barked, "Who's your supervisor? I want to know who it was, and where you got the gems!"

"Information classified!" Oboro said, as she continued to fight back at both of them, "Bring it. But I can handle your sword strikes."

He rushed to her, as Oboro ducked Shido's strike. But she miscalculated on Tohka's deep slash towards her chest. She hit it, dead-on, and suddenly flew into the walls. She stumbled down, and kneeled up. She ran towards them, and started to land severe kicks to both of them. They blocked the attack, as Oboro sweep Tohka off her feet. She dropped down to the floor, and Oboro would grab her by the arms. She then proceeded to kick her knee into her gut. Shido pried her off, but Oboro lands a swift right to his face. Shido stumbled to the floor, but Tohka grabbed Oboro by the skirt. She swung her sword onto her spine, and ripped most of her skirt off. Oboro fell, faced down, and then Tohka would grab her legs and stomped on her crotch. Oboro moaned in pain, while Tohka lifted her legs up and slammed her on the ground, facefirst. Shido moaned, as he was getting up. He said, "Thank goodness…"

She said, "I guess she wasn't a good fighter… Plus… did I just-?"

She gasped, as she looked up her skirt. She whispered, "Oh, god… Not this again…"

Shido asked, "What happened?"

Tohka's face went pale, as she saw Oboro's crotch. It had a bulge on it, as Shido whispered, "My word… Wait… This Oboro girl is really a dude?"

Oboro came to, as he was groaning, "You guessed, didn't you? No one was to know, anyway…"

"Why the disguise as a girl?" Tohka asked.

Oboro said, "I only joined the cause, to unearth the huge power crystal that we found, from my supervisors in the Tokyo District. We were assigned to study this new gem in the deep underground part of Tokyo Tower."

Shido asked, "Wait… So, your gems are powered by Tokyo Tower?"

Tohka said, "The gems we know of were from Mount Fuji and Fuji Forest."

Shido shivered, "My goodness… But that doesn't explain why Miss Oboro here has a dick."

Oboro got up and said, "That's because, before she recruited me, Miss Kajou, the head of the project, wants me to be the prototype. But in doing so, I would think like a woman, and act like one. If I am ordered to be a woman, I'll be a woman. If I want to be male, I'll go and dress male. It's not because of gender-swap… It's because I'm ordered to do so."

He cracked his knuckles and said, "But you two ought to be ashamed of learning my secret… being I was only leader of the expedition, to learn more about the KEION Bu. But all we could come up with was a dead end… and powers that our androids would succumb to. Miss Kajou was created to lead our people…"

Tohka asked, "Androids? Wait… Your boss is an android?"

Oboro said, "I don't approve of her dirty and lewd talk, but she was built to help the Rhombloids, since she was Rhombloid #1, a perfect project created to observe, protect, and destroy."

Shido gasped, "Destroy?"

Tohka said, "KEION Bu is known to make a perfect world, via world domination… What do the Rhombus Robots do, if they succeed?"

Oboro smirked, as he did a fighting stance, "The KEION Bu was to make a perfect world. We're here to observe and procure the human race… Unfortunately, the human race has become hostile and life threatening. Our true goal, as we find ways to control and harness the energy, is to find the perfect solution on what to do with the Rhombus Gems… and use it to make soldiers of the city. We're making superhuman super soldiers, to protect this city, and the country, at all costs."

Tohka growled, "You are evil… For someone who wears drag, and playing female, for a role you want to play, you're sick and twisted."

Shido asked, "But why the robot of Tohka?"

Oboro said, "THAT was for you to join us… and possibly bring Lan Hikari in. Your files said it all, and from Ginti, who told us everything, we managed to did some research into you. Too bad we miscalculated on your swordsmanship. But this time, I cannot fail."

He did a stance, as they prepared their swords. He scanned them and said, "Right. I can easily take you down, and make you two the next subjects."

He charged at them, and began with Shido. He ducked his blade strike, and landed a swift punch to his chest. Tohka gasped, as she growled, "MONSTER!"

She swung her sword at Oboro, but kicked it off her hand. He landed a swift barrage of jabs into her chest. Tohka collapsed like a rag doll, and was out cold. Oboro said, "All too easy. You two are trespassing in our research lab. Now, I shall inform Miss Kajou of the new test subjects."

He left to call Ayame, as Tohka opened one eye. She whispered, "Is he gone?"

Total silence. Tohka got up and brushed herself off. She said, "Good. I figured if I would play dead, he'd leave us alone…"

She helped Shido up, and he groaned, "Man, what was the number of that van?"

Tohka said, "No time! We have to leave, now."

Shido asked, "But what about your friends?"

She said, as she was worried, "I'm sorry, Ginti…"

She stated, "We'll worry about them, later. For now, we have to find a way inside. But we need a plan."

Shido said, "Let's hope you're right. I want out of this place, and soon."

Tohka smirked, and then kissed him. She said, "Just quit worrying. Come on, before that guy comes back."

They escaped through the front door. The doors were locked tight, but Tohka smashed the glass with her sword. She and Shido carefully went through the glass door, and ran off.

Moments later, Oboro returned, seeing glass shards on the floor. They then said, as they was annoyed, "They escaped. Fine by me."

Miz-K NOTE: For the remainder of this fic, Oboro will be referred to as "They", despite that he's biologically male. But whatever gender Oboro plays is how he/she is assigned as.

They left to another room, as they called on the phone, "Hello, techs in lab? This is Tsukimigusa. Yes, I am available for standard research… But I'm busy with two subjects that escaped… Tohka Yatogami and Shido Itsuka. Have Tohka-Bot picked up for disassembling, and prepare the SAIA."

They responded, as they nodded, "Uh-huh. SAIA is operational? Good. Hunt down the two, and bring them to the lab, at once."

They hung up, and then said, "Now, Yatogami, let's begin the process of elimination. I promise you: no one escapes Tokioka Research… alive."

Meanwhile, in an underground lab, a girl in long black hair, with no clothes on, and with a dark red rhombus on her chest, was lying on the metal table. The computer started to beep and make noises, as it started to boot up.

SAIA starting up…
Project R-D-BL00DC… SAIA online…
Beginning objective… Search and capture…

Her eyes opened, as SAIA sat up, showing red demonic eyes. She then slowly sat up and said, "SAIA ready for battle. Objective confirmed: capture Tohka Yatogami…"

She sensed Tohka and said, "Target spotted. Beginning mission."

She got up and went to another room to get dressed. She was dressed in a black and red school uniform, while her hair was done in pigtails, in red ribbons. She was also wearing glasses. She held her arm out and produced her katana. She raced off to find Tohka and Shido.
