Reincarnated with Annihilation Maker in a Mash up Anime world

In a house somewhere in Chinatown that's near the 9SC venue.

The Twins of Saegusa family are being held captive in a room with a big sofa where both of them are sitting on it. They are also seems to be just finished drinking just based off the empty tea kettle and tea cup place on the coffee table in front of them. As far as being kidnapped, they don't looked the part because there's also a flat screen TV hang in the wall that twins are looking at and watching the News Channel replaying what happened to 9SC venue.

However in the surface, Kasumi and Izumi might looked they comfortably just sitting but if anyone looked closer they shaking as they watched the news on the TV about the attacked on the 9SC venue. The reason for that, is they are worried about their beloved Onee-sama well being even if they believe that Mayumi can protect herself, they'll never know if something unexpected happened to her.

"Those traditionalist bastard!" Kasumi shouted angrily while standing abruptly to her seat.

"I hope Mayumi-neesama is okay" Izumi said softly while she held her hands together praying for any God out there to keep Mayumi safe.

"Damn it! If only we're there with her but the timing of us getting kidnapped is impeccable!" Kasumi shouted because she can't help. She stared at the TV with worrying eyes.

The Twins are more worried to their sisters well being than their safety. This automatically makes them a very loving and good sisters to their Onee-sama.

Kasumi then turn her eyes off from the TV to the door looking at it deeply and thinking for a while before walking towards it with a stamp of her feet.

Seeing this, Izumi asked "What are you doing?" Though don't need to asked because she already know what her Twin was about to do.

"I'm going get us out of here, pronto" Kasumi said as she prepared to used her Magic.

"We already tried many times! and it's always the same result" Izumi reminded Kasumi of their futile effort to destroy the door from the beginning after the culprit brought them here.

And the reason for that.

"I don't care! it's better than doing nothing and mopping around!" Kasumi shouted after she prepared a simple magic.

As soon as Kasumi casted her magic, PSION noise bombarded Kasumi which resulted for her magic getting canceled and her getting dizzy. She was not only that got hit by the PSION noise as Twin also bombarded by it but she did get headache or vertigo because she didn't use any magic.

Kasami slowly fell on her butt while walking backwards slight. After she hit the floor, she shook her head to get her bearing quickly before standing up again. Izumi run towards her and help assist her. "I told you so" Izumi said with sigh.

"I already know that, I just want to try again" Kasumi said a bit angry at Izumi's sassy remark but she still thank her for help her to stand up. "This guy's are loaded with money" She said while looking at wall of their confinement room.

The walls contain Antinite, a material used to cast Cast Jamming—a magic that floods an area with random Psion waves, creating "noise" that disrupts meaningful Psion activity. This interference overwhelms magicians' CAD data transmissions, preventing them from forming effective Magic Sequences. The Psion noise spreads rapidly and randomly across all types of Systematic Magic frequencies, effectively blocking all Psion transmissions.

"They just don't need money, they also need Military Connection." Izumi added before looking at the Camera that was watching them and the speaker beside it "And I don't think the Japanese Government would sell to someone that will use it to their compatriots" She added not thinking how naive she's by saying that because their government would likely do the opposite of what she says as the JP government are pushovers and no back bone.

Kasumi agreed to her Twin's conclusion.

"Oi, stop doing as we don't want to waste to much of our Antinite" The peson in the speaker said "you're also making lose my money" The person added.

"I don't care! I'll do what I want to get the hell out of here" Kasumi shouted.

"We'll if you going to be like we're to....huh...who are you?"

After asking that blood curling screams can heard from what seems to be different kind of person and cow like sound also can heard from the speaker. The Twins who were hearing all that assume they getting absolute fucked but they don't know who or what. They have a wild guess that they are getting ripped apart by that cow that they are hearing.

"Please.... spare! I'm just...Stay away!" However the person was not able to finished the sentence as a sound of something getting chew on and gargling of human dying resounded Then after, it's all...silence making the Twins wait nervously while sweat form on their foreheads as they awaited for someone to speak again to them.

"Is this thing still..-" A screeching sound reverberate in the Twins room forcing them to cover their ears out of pain.

"Arrgg" The Twins uttered.

"My bad, my bad"

The Twin recovered pretty quickly as they recognized the voice on the other end of the speaker. Both of them got up and shouted "Aniki!"

-

Befor Aniki or Oreki killed the people in the monitoring room.

There are at least 15 people inside this room.

There are various Monitors or TV projecting different parts of the compound that they were guarding at. There also various console to control a dedicated camera and microphone to do an instruction if they see something to the camera.

The people using this tech are not really doing their job properly but it's understandable as there's no one brave to attack or infiltrate their fortified compound. What they are currently doing is just laughing while playing cards with each others and of course they bets in the middle.

"This job is really boring" one of them said.

"Agreed, the Boss should have let us attack the 9SC too"

"Yeah, I've been itching to kill to something and if only, just like so said made us attack the 9SC too."

However they got distracted by the large monitor near them. The screen was projecting Kasumi standing up and walking to the door.

"Damn it this girl again"

They all looked at Kasumi before laughing and started betting on how long she gonna last standing up after getting hit by PSION sound waves. While they are betting, Oreki who sitting not far away from them as if he's one of them though they didn't notice or they don't see him at all. He looked at the monitor and see Twins' prison wall is surrounded by Antinite.

Oreki contemplate how to kill these guys while looking also at Kasumi's attempt to used magic before kneeling down. He then look at the guard laughing at the sorry figure of Kasumi. "Annihilation Maker" He thought as he remember he hadn't use this Sacred Gear in a while.

Oreki disable his ForgetMeNot Skill "Wildmutt! I choose you" he used the Sacred Gear in him to create one of the 10 Original Aliens of Ben in his Omnitrix, Wildmutt.

After hearing Oreki shouted the name of Wildmutt, the guards turn away their sight from Kasumi to Oreki. They're eyes widen when they saw that the dog like figure standing in all fours beside Oreki. 

Wildmutt had muscular body covered in rough spiky orange. He has no visible eyes, relying on heightened senses to detect his surroundings. His face features a wide mouth filled with sharp teeth and a long purple tongue. Wildmutt's limbs are powerful, ending in clawed feet and hands for climbing and combat. His appearance resembles a cross between a wild animal and a beast, giving him an intimidating, untamed look.

Oreki patted the body of Wildmutt before looking at the confused guards and saying this with a smirk to the new pet "It's feeding time"

After hearing that, Wildmutt roar and pounce to the nearest victim ripping the head along with spinal cord before tossing it up in the air and catching the head with his mouth. While chewing the head, Wildmutt pounce again to the others ripping them apart limb by limbs and eating them. They tried to used magic but it all useless against Wildmutt because they're weak and that's the reason they here watching cameras here not in field.

After hot minute, the Monitoring room is painted red by blood with some guts and bone as a new decoration. "Good boy!" Wildmutt responded with a bull like roared "But I hope you're not full yet because there other lurking around to eat" He added. Wildmutt growled and Oreki's interpret that he's still hungry.

Oreki tapped WIldmutt's body before saying "Go wild! mutt Heh" He chucked. Wildmutt oblige and run towards the door destroying it in the process. 

With that done, Oreki walk towards the mic and speak towards Mayumi's sisters.

-

"Aniki! Is Mayumi-neesama safe?" Izumi asked.

"Aww... that's so cute of you girls for thinking of your Sister's safety before yours" Oreki praised in sickeningly sweet voice.

"Isn't that obvious that we should worry about our family" Kasumi replied while her arms cross. She blushes slightly after being praise by Oreki a bit.

"Even though we were kidnapped our state are better compared to the ones that got attack and killed in the 9SC." Izumi added and she also blushes a bit.

"Now answer the question Aniki!" Kasumi demanded. 

"Instead of answering why go to her instead" Oreki replied while appearing in between Twins which resulted for the Twins to get jumpscared.

"Aniki don't do that!" Kasumi shouted and Izumi nodded in agreement before she says "Please bring us to our sister"

Oreki nodded "Watch your step" He said while creating a portal beneath their feet that was connected to Mayumi and Student Council group current location.

"Wha.," Before they could even react and look down, both of them fell down and startling the group on the other on the other side of the portal.

"Now where is... AH found him" Oreki said while disappearing from the room.
