Reincarnated with Annihilation Maker in a Mash up Anime world

Recovering from their stupor, The students barrage Oreki with different questions. Kudou just smiled upon hearing that while Miya sighed. Maya too burst up laughing replacing the laughing fit of Yoruichi after the latter left.

"Oreki! Are you insane? what if they hurt my sisters or worse kill them!" Mayumi shouted as she looked at him with worried eyes.

"Maa, Maa, Maa, they won't touch them or he won't touch" Oreki replied nonchalantly while waving his hand back and forth.

Seeing Oreki is not that worried as if he got it all under control, Mayumi calms down before saying "I'll trust you" She then turns to her friends that it will be over soon making them wonder if Mayumi is thinking properly but then Mari reminded them something that Love is blind so just leave it.

"Just like your boyfriend but literally," Oreki said with a smirk making Erika laugh out loud. Mari wanted to jump at Oreki but she turned to Erika reprimanding the latter that he was insulting Erika's brother. In the end, Erika does not care as she's still salty that her brother got together with Mari.

"Umm... Do you really plan to..." Honoka wanted to ask, but Oreki completed it for her so as not to dirty the mouth of the innocent girl "Massacre them scorched earth style?" He asked the girl with a smile and the latter nodded "Nope, but unless someone wanted to use classified magic called Material Burst" 

Tatsuya just sighed upon hearing this while Miyuki just laughed lightly and the ever-observant Erika noticed this making her think of something while looking at Miya and Maya too with a frown on her face.

Mizuki asked if something was wrong with Erika but the latter just said that it was nothing. For having a special eye, Mizuki is as blind as a bat.

"And if anyone is asking what our group is going to do," Oreki said before looking at Maya "We're going to do what the Yotsuba would have done in the past during the kidnapping of one of their own". He explained.

"And that is?" Shizuku asked.

Instead of Oreki answering, it was Maya who "Kill everyone involved, from the top and bottom" The students looked at Maya's cruel smile making them shuddered.

"We start with...." Oreki said, pausing for a bit waiting for the right moment and viola. "this one" He pointed to an empty small beside him but not for long as Yoruichi arrived, and with her in tow was a girl named Hashibami Yuki who for some reason is naked.

Seeing the boys turned around except for Tatsuya but Miyuki covered his eyes with her hands. "Onii-sama why didn't you turn around?" She asked.

"Because I didn't need to as I don't feel any perverted thought for her," Onii-sama said but Miyuki insisted that he shouldn't look no matter what. 

Oreki looked at Yoruichi "I assume she's taking a bath while you capture her?" He asked with a smile.

Yoruichi nodded "She's trying to erase the scent of blood from her body," She said.

Mari looked at Oreki "Hey cover your eyes pervert" She reprimanded.

"She's not my type and the same with you" Oreki replied.

"You..." Mari wanted to retort but Mayumi calmed her down by saying Oreki was just joking around before turning her attention to the naked girl with a gag in her mouth "Who might this be, Oreki?" She questioned.

"Well I'm glad you asked because this one is an assassin hired by the No-Head Dragon and she...is involved in the kidnapping of your sister" Oreki explained making Mayumi clench her fist "As for the details of her specific involvement. It very simple" He said pausing for a bit and looking into her eyes directly "She killed the bodyguard" He whispered but everyone in the tent could hear as they gasped.

Mayumi's clenching fist clenched further but it softened after hearing what Oreki said next.

"So I would to present her to the Saegusa family and do the honor of killing her," Oreki said looking at Mayumi.

"Wha... me?" Mayumi asked nervously while thinking of the consequences of taking a life.

"Oi... Don't involve her in that" Mari said angrily.

"I mean, I specifically said that the Saegusa family should kill her" Oreki explained again.

Mari wanted to retort but out of nowhere, a man with sunglasses entered the tent and this was none other than Saegusa Kouichi.

"Then let me deal with her," Kouichi said before releasing a pressure bullet and its trajectory is towards the naked girl. Yuki's eyes widened seeing this, she wanted to dodge but her reaction was too late as she got hit on her forehead leaving a hole on it while obviously bleeding from it.

"That was a good entrance father-in-law," Oreki said while giving Kouichi a thumbs up "Also quite rude of you for killing her smoothly and getting my uniform dirty." He added as he looked at the blood on his uniform because he was in the splash zone.

Kouchi ignores Oreki casually calling him father-in-law and it's not because he does not acknowledge Oreki's existence or potential to be son-in-law. In fact, he already accepted him as a soon-to-be husband for his daughter, Mayumi. "Do you really have the means to bring my twin daughters to safety without even a hair of their losing from their kidnapper?" He questioned in a serious manner but if anyone can see through that face of his, they can tell that he is worried sick for his daughter's safety and if someone really happened to them, then he'll go ape shit to Zhou Gonglin, Gu jie or even the Great Asian Union without even a concern for his safety.

"Father-in-law, don't worry about them, leave their well-being to me," Oreki said.

Kouichi nodded and accepted easily because Oreki had already proven his ability after he watched Oreki in action in the Ice Pillar game against Masaki. He then turns his attention to his former Master, Retsu, and his former fiancee, Maya "Whatever plan both of them are going to do. Count me in" He said.

"Marvelous! With this the Axis Clan is completed" Oreki said while clapping. "Now let's get out of here and let's the adults discuss adult stuff," He said as he started walking out of the tent followed by the others.

After they exited the tent, Mayumi and the student council girls said that they wanted to check up on the other First High students to see if they were okay or not. They then part ways except for Miyuki as Oreki has something for her to do. 

The DxD group also leaves to do their own thing because after the coordinated assassination that they're about to do later tonight, they'll be leaving this world but they can still comeback from time to time if they want to as Oreki is the Embodiment of Doors.

Oreki then told them to be back on time for the main event of the evening before walking again while Tatsuya and Miyuki followed him.

Tatsuya's friends did not leave because they didn't have anything better to do.

"Where are we going Oreki?" Miyuki asked.

Oreki did not answer verbally as he pointed to the dead lying down the open field that they passed through earlier.

"Are you going to do your voodoo magic and revive?" Erika asked in a crass manner.

Oreki looked back and asked with a frown on his face "Didn't I tell you guys, I won't revive them yet." He received a No for an answer from them. He realized that he only said it to Retsu and Yotsuba Twins before he told them his plan while they walked until they reached their destination.

Miyuki then looked at the corpses covered in white fabric "So do you need me to do something to them." She asked with a painful expression as she did not like seeing this sight.

"Preserve them" Oreki replied. "Preserve them?" The group collectively frowned as they uttered the same question.

Miyuki looked at Oreki with an incredulous look "You mean I should Freeze them?" She questioned and Oreki just nodded.

Miyuki looked at her Onii-sama, silently asking Tatsuya if she should do it. Oreki asked, "Is freezing without harming hard for you?" She nodded.

After that, Oreki closed his eyes for a bit before opening it again and saying confidently with a smile "You can do it now!"

Tatsuya and Miyuki frown but they trust Oreki. With that said. Miyuki stepped forward and used AOE Freezing Magic and the effect was swift scaring the Staff and police lurking around.

The relatives of the deceased who were weeping did not even know how to react seeing the frozen state of their dead relatives or friends but some of them got angry and looked around to see who the hell did this to their loved ones. However, Oreki just uses magic to calm them down and make them think it is a good thing that they are frozen. The police and staff too were not exempted.

"Now that's what talking about! Good job" Oreki said a good job in a weird accent while giving Miyuki a thumbs.

"I can't imagine Miyuki using that in a living person," Leo said while hugging himself as he shuddered. The rest also did the same.

"Well ladies and gents, my sisters-in-law needs me, So ADIOS!" Oreki said as vanished swiftly.

The group looked for a while at the empty space where Oreki was previously standing. 

"What do we do now" Mikihiko asked Tatsuya but he noticed that he looking at something or someone Mikihiko turned his sight to what Tatsuya was looking at.

"Tatsuya!" shouted none other than Fujibayashi Kyouko. Who were running towards their group or Tatsuya and after a while, she arrived in front of them.

"Kyouko-san, is there something I do for you?" Tatsuya asked making Miyuki frown because she knew that they would demand something from him again but she was okay with that as Tatsuya wanted to help them too.

"Major wanted to meet you ASAP!" Kyouko said in a serious manner.

"Major?" Erika questioned before turning to Tatsuya and expecting an explanation from him. The others too are waiting for him to explain but Tatsuya ignored them entirely.

"Lead the way" Tatsuya replied but they didn't leave yet Kyouka turned her attention to Miyuki "You too Miyuki," She said.

"I see" Miyuki closed her eyes after saying that and she also understood what was going to happen next.

Kyouka nodded that Miyuki understood quickly what she meant. She signals them to follow her as she'll lead them to meet Major. The Shiba Siblings followed her swiftly leaving Tatsuya's dumbfounded friends.

The Shiba Siblings were already out of sight when they recovered from their stupor. "So does anyone want to do something and leave?" Leo asked.

Shizuku looked at the frozen bodies "I wanted to eat ice cream" And they did.
