*Beep beep beep*

Alex: hmmmm alright I'm up so stop beeping

Beep beep beep

Alex: oh yeah you have to turn these things off

( after getting dressed and leaving his home Alex is surprised to find rias, issei, Asia, kiba, and the Akeno girl from his school)

Alex: oh why are all you guys outside my house on the weekend ?

Rias: we came to introduce you to everyone in the occult research club save for two people

Akeno: I didn't get a chance to see the fight but I heard you are quite strong so I appreciate you joining up with us

Analyze Akeno ( power level: 13,000
Magic: 7,000
Strength: 3,000
Spirit: 3,000)

Alex: hi but I don't get why this couldn't have waited till school on Monday I was heading to train a little

Issei: sweet let's train together all of us can stronger that way

Kiba: that's not a bad idea but Alex may not want the company

Rias: I don't think we need his help getting stronger I'll mange just find with my methods ( due to her somewhat rivalry with Alex)

Alex: actually let's do it training with other will be good for me and it's been a while

( after everyone except rias agreed they were on there way to the battlefield much to rias annoyance with Alex and training began
Akeno against kiba and issei and rias against Alex as Asia practiced her healing abilities with help from Alex's books)

Issei: alright right off the bat I'm going to use this

Boost.  Boost

Rias: I agree we should be serious from the start

Alex: not bad but this training together thing is gonna be good

( and so the began the training went on every weekend and some weekdays after school for three months)
