The Information

Takeda with Korosensei just walked to the school, but then, Takeda's phone rings, and Aven gives him some news on his phone. when Takeda sees the content he immediately stops and he's expression although it's calm, Korosensei notices that Takeda's emotion became angry.

"Korosensei, can you tell Karasuma that I am skipping today? I have some business that I have to take care of" Takeda said.

"Hnn... If it's important then okay, But you have to treat me to a BBQ!" Korosensei said. Takeda is speechless but it did calm his mood.

"Haa... Alright then, tomorrow then. I am off" Then Takeda runs back to his house. Korosensei seeing him leaving thinking.

'The calmer the person, the more dangerous he becomes. I know from Takeda's personality he's not going to kill a person unless it's necessary. Whoever the person that anger's Takeda, I already feel sorry for them'

"Maa, with that let's just steal Karma's lunch for my food, nurufufufu~" With that Korosensei fly to Kunugigaoka.

Back at Takeda, He Hurriedly runs to his home.

'Aven sends a text to me contains some information of that lunatic guy, Professor Yanagisawa. Aven knows that I become a teacher at Kunugigaoka so he compiled information that is connected to that school. The government is getting ready for Itona transfer from that lunatic but he codename himself "Shiro" ' what he found is more disgusting than he thought.

when he is at his home, He wears his Akatsuki Costume that being modified with some heat resistance metal weave thanks to his sewing. (A/N: Sorry if I am not clear. That sewing max skill can literally sew anything easily, including closing wounds).

when he wears his Tobi mask he checks everything, and the last thing is the Kusanagi sword. He made it using weapon creation but the difference is, that sword is on another level of power than the original. It can do a lot of damage to evil god and if you imbued it with Amaterasu Fire and Chidori Lightning, it can kill.

'Now that I am ready, first, let's see the content again. What I am shocked about is Professor Yanagisawa's test subject. one name is struck out to me. Yukimura Aguri, She's alive... and That bastard used her as a lab rats or as the file say "Sacrificial lamb". I want to kill that guy, but Korosensei can do that. and the connection that he has pointed to 2 towns'

He opens both of the town files.

The first is Kuoh. High school DXD is here. then that means, he may already made a contact with some fallen angel or devil for the subject. then the second one it's where Aguri is... no He just placed Aguri there and the other subject is in Kuoh. The other one is Ishiyama, and It's closed to the Shingetsu dojo and shrine. So both Beelzebub and DXD are here? then what about the 4 great satan and Great demon lord or Lord en connected in this world?'

He really wonders about that but he is in a hurry so he put his phone in his pocket. his eyes changed to EMS,

'Kamui!' and he spiraled and teleported.

Takeda arrived at Ishiyama town and he already seeing the facility.

'The guard at the front is just a normal human. outside security is not that tight, but inside the facility, there is some dark energy. That means either devil or fallen angel is inside'

Takeda then proceeds his pursuit. first, he put the human down with his Sharingan and they are all pass out. since the guard outside is very little then it's easy and quick for him to put all of them to sleep.

'Now, Time for a massacre' He said in his mind. he calmly walked inside but his walking can consider having no sound considering he's using KI. one of the guards found him and it's a fallen.

"Who are you Human?! you're going to make a nice meal for me" The guard said. then Takeda said with his voice deeper than usual.

"You're just a pest" Takeda said.

"What?! how dare-" before he finished his word Takeda shunshin to him and cut clean his head.

"One down, more to go" and with that, the killing begins. the fallen here is slow and their reaction is dull. Takeda just swings his Swords while walking. He avoids some hidden attacks by using Haki and just Kill them using Chidori. he almost kills all of the fallen. he finally goes to the last room.

What he finds is some high ranked fallen, imbued some dark energy to her.

"You're rowdy aren't you? you killed my guard. no matter they are just waste anyway" The fallen said. Takeda just becomes quiet, but his emotion is angry to its peak and the Sharingan already changed to EMS.

"Ohh, where are my manners. since you're going to die, I am going to introduce myself so be grateful. The name is Haizel" the Fallen, Haizel said. Takeda doesn't care.

"You talk too much" and he activates Haozhoku Haki to put him to pressure.

"W-what the?! you're not a normal human aren't you! who are you?!" Haizel asked. he can't move because of the pressure Takeda gives.

"Your doom" then He slash him to pieces. to him, Haizel doesn't deserve to live.

when Takeda is done, he put his phone to the computer and connects it to his phone.

"Aven, copy and destroy every information and file in the lab" Takeda said. Aven then starts working.

Takeda then goes to Aguri and check her condition. he checked with Sharingan but that's not enough so he changes it to EMS.

'She becomes almost non-human because of that dark energy. let me used recovery on her' then he put his hand on Aguri and starts to heal her. but it doesn't work, it just lessens the dark energy by a minuscule.

'It's not even working, it just stops and lessens for a bit. hmm, how about I check inventory if there is something useful'

then Takeda checks his Ability Inventory and there is nothing useful for the current situation. the highest-ranked in the inventory is B.

'My luck is out huh? sigh let's just think about it later and get out of here'

when he carries Aguri, the floor is shining with purple energy, and a summoning symbol is seen.

'That bastard! he secretly activates a summoning while I pressured him!' he hurriedly takes his phone and Aguri out of the facility. he shunshin to the outside of the facility and what came out is something monstrous.

'The fucking hell!! 5 Cerberus and 3 chimeras! And they even imbued a power-up!'

but what he didn't expect is they ran in the other direction.

'Huh?! where are they going?' and the direction the 8 demonic monster heading is the Shingetsu shrine.

'Shit! They going to that shrine! I have to stop them!' He put Aguri in his Kamui dimension and quickly returned.

'I have to catch them!' then Takeda Shunshin as fast as he can. He catches up to one of them. He takes out his Kusanagi and Imbued it with Amaterasu. then He slashes the first Cerberus he catches up.

"One!" and the Cerberus instantly die with a roar.

*Roarr!!!* and that alert the pack but he immediately slashes the other Cerberus. and another one while Running.

'Why are they not attacking me?' don't tell me there is something that draws them to it? but it makes it easier for me!' and he slashed another Cerberus. this time 3 hit with Chidori imbued.

'Three more to go' and he chases the Chimera. the Chimera is faster than he thought so it's harder to aim, but it's not impossible. he then used Gravity Magic two subdue them but it just two that hit with his magic.

"Shit! I let one running away!" the radius of the gravity magic is shorter than he thought. he immediately crushed them with 100x gravity. then he immediately chasing the last one.

when he did, He sees a teenage girl and a little boy who is outside.

"I have to be fast!" and he shunshin again but this time, the chimera is too close to them. the Girl that seeing the chimera is surprised but Immediately cover the little boy.

"Oh no, You're not going to hurt them! Gravity magic!" And the chimera is flattened. luckily the girl is covering the boy's eyes and he immediately uses Amaterasu to completely eliminate him.

'I have to be faster huh. Haoshoku Haki is not working on them, so they are mindless? and shit! my martial arts have no effect on them. even when I used KI. I have to train more' when he thought that he remembers about the girl and the little boy.

"Are you two okay?" He asked them. The girl with shrine clothes answer,

"W-We're fine. Thank you very much for saving us" She gratefully bowed. The little kid is thankfully just confused. Takeda then notices that the girl has a demon lion. Takeda already know her and thought that She tamed him. he asked,

"Are you taming that Demonic Lion?" Takeda asked. The girl is shocked that he knows. but given the current circumstances, he might know, so she protected the little boy.

"Calm down. for now, please move the little boy to a safe place. I want to have a conversation with you" and that girl then told the little boy that she called him Kota to go play somewhere else. The little boy nod and go somewhere else.

"Alright then, how can I address you? You can call me Tobi by the way" Takeda said.

"Why should I trust you?" She's clearly wary about him.

"Well, I saved you guys from that Chimera, and if I am suspicious, I can just literally attack you and let that Chimera going Amok" Takeda said with a fact. She seemed convinced and nod. then she introduces herself

"I am Aoi. Kunieda Aoi, nice to meet you Tobi-san"
