After aleister death while fighting corozon with the help of imagine breaker and the one with the power of god {accelerator }, aleister choose to leave the future of the academy city in the hand of those two.

The Windowless building :

In the darkness of the room a figure can been seen and anyone who live in the academy city know who is this person now. Once he was know as the top dog of the city, the strongest level 5 and now he add a new title to himself

The academy city board chairman|and before him stood a blonde hair teenager who seems he's same age reading him a report.

"Ah it's so boring here why did I accept the request of that bastard Aleister. "

"Earth to accelerator oiiiiii!  Are you still with me should I continue reading you the report nyaaa!!! "

"Tsushimikado why the fuck I should care about what aleister is hiding in his 

Batcave...  Your the expert on magic not me also stop talking like that or I will sent you in a mission to mount Everest and you want see your sister for at least for 3 years ".

"Ehhhhhhh!!!! But I was just doing my job you told me to check if aleister left any magical item that could cause trouble nyaaa!!!! ".

"And what I ask was a report not a fking headache I got because of you telling me about you and your sister vacation for three hour now ".

"Kufufu poor Accelerator after you become the big boss you seem that you aged well haha haha!!! ".

"Musajume if you want to know how it feels to age i could send you to prison for 40 years if you want ".

"Geh your jo-joking right you couldn't do that to such a beauty standing in front of you righhhhht".

"Tch let's just get to business can't we I had enough of idiots for today. So what did you find in the basement Inabara".

"Well after doing some reaches about the vault I found it was locked by some defensive spell I couldn't find a way to open it".

"It need some kind of password do you have any ideas accelerator ".

"Tch, how the fk I should know? If it's magic it's your domain right ".

"I never saw a spell so complex like we could try to call kami-yan maybe he can help us with the imagine breaker ".

"Tch, the hero hein...  no not for  now I will go and see it my self. Maybe that garage demon could crack the code".

Just when accelerator was going to check the basement he was almost hit by the door that was sent exploding toward him.

"Tch, you just returned from your mission and already looking for trouble!!!! Fairy face ".

"Hoho and me we though I could kill to bird with a rock,  Well too bad ".

From the double door appeared the number two looking as pridfull as he always was.

"Too bad my Ass! Money doesn't grow on trees smart ass I'm citing the reparations fees from your salary".

Just after the convention enter the rest behind kakine, the rest of level 5

#3railgun misaka mikoto.

#4meltdown mugino shizuri.

#5mental out shokohou Misaki.

#7attack crash sugiita gunha.

Just after entering the room Misaki started making remarks about misaka budy and sparks starts flying, Gunha hit accel on his back saying its not good for heath staying all time here and he should show some guts.

And mugino who started laughing at kakine because no one told him he was wearing his T-shirt backwards.

Seeing them like this and if someone told you that they wanted to kill each other once seems like a lie right!

Well no it was accel who created the level 5 council after promising that each of them who have benefits working with him.

First the stopped all the illegal experience on poor children so no others casualties happened like with them.

Second every level 5 had a job to do in the city mugino and kakine work on to destroy the remains of the dark side,

Misaka is helping the anti skill the keep the peace in the city, as for Misaki accel advice her to work as her secretary which shocked every one in the room but her main job was diplomacy and to keep a good relationship between the academy city and the rest of the world, As for gunha he was order to keep the academy city safe from any outside threat.

"so your saying there is a secret vault in the basement of Aleister that is protected by some sorta of spell I'm I right! "Said shokohou as she was the only one who get it.

"Yeah I was just about to check it now if that fairy boy didn't try to attack me!!! " kakine averted his eyes from accel red eyes.

"Well join you! The more we are the funnier it is " reply gunha while holding kakine under his arm and dragging him around.

After walking down stairs, the group finely reached the vault that Aleister kept hiding until now.

"Woooowww! So this is what Aleister was keeping around a portal" gunha look at it with excitement.

"What's this it's seem like a suit of numbers like a hidden message" told shokohou after touching the portal.

"It's mathematics problem as far as I see... Wait this is Pi I'm a right!!! "

Declare tsushimikado after analyzing the number.

"Yeah it seem soo, but we don't know what is this portel it could be dangerous. Tch really the previous chairman left some occult give to me and without mentioning what it does". Told accel annoyed by the fact this could be some weapon of the magic side and they don't know what it it.

"Hey tsushimikado don't you have any idea on what is this your the magic expert Here didn't Aleister mention it before".

After some time checking the portal and not knowing what it is the group decides to give it was to dangerous keeping screwing with something unknown but just then gunha stop them on there tracks.

"I figure it out the code haha haha as expected of my guts! The code is 82".

Just after this something started moving as if the door is opening and the cave started shacking, then the portel that was closed just a sec before opened and what seems like a red light from it.

Just like a black hole the Portel absorbed accel and other level 5 leaving only mikado and others loking surprised by the what just happened.
