7 days Training

"BUCHOU!" Asia burst into the Occult club making everyone turn to her. "What wrong Asia?" Rias ask worry seeing the panting blonde, Asia open her right hand showing a letter "I just found it this morning".

Rias take the letter from Asia and began reading 'Rias I won't be training with you and the others, I have other important things I have to deal with before going to the rating game, train hard and don't worry I'll be there in time' Rias bit her lips and clench the letter "Buchou what's in the letter?" Akeno ask snapping Rias out of her thought.

"Here look for yourself" Akeno takes the letter, her face turn into shock "Huh okay everyone we are heading to one of the Gremory house in Kouh, we will be training there for the next 6 days, the last day we will spend resting and prepare for the rating game" Rias said.

"Buchou what about Teme isn't he coming?" Issei ask "No it seems that Nawin-kun has some other things he need to do… so he won't be joining us" Rias reply shocking Issei.

"But why now off all time!" Issei yell piss "All we can do now is hope that he will show up in the Rating game… now then grab all your things we're moving out".

Time Skip

Rias and the others arrive at the training field after putting all their bags back in the house. "Now then Issei, Asia" Rias call out making the two walk in front of her "Since you two are still new in this, you two will have to train really hard and fast okay" Issei and Asia nods with determination going through their eyes.

Rias turn to her Knight and Rook "Koneko, Yuuto these are training weight that I got from my brother a few days ago, he said that these will be perfect for training you two" Rias passes the weights to the two "Put each of them on your wrist and ankle, after that I want you two to run around the field ten time" Koneko and Yuuto nods.

"Okay Issei, Asia. Me and Akeno will be training you two understand" Issei and Asia nods, Rias turn to her queen seeing her in deep thought making the red head sighs 'She must be worried about Nawin-kun…'

Rias place her hand on Akeno shoulder snapping the raven haired out of her thought and turns to the red haired "Akeno we can't stand here worrying about Nawin-kun… he want us to train so we can be prepared for the rating game, so come on you don't want to disappoint him now would you" Rias smile, Akeno nods smiling back.

"Okay you two me and Akeno will start teaching you how to control your magical ability better, since the stamina you two have are really low, we don't want you to fall into exhaustion in the middle of battle" Rias said, Issei and Asia nods summoning their sacred gear.

"Asia your sacred gear can do more than healing, from what I research it allows their user to summon an energy projectile that you can use to fire at your opponents" Rias said surprising the blond "I want you to try and concentrate… think that your forming a spear in a palm of your hand" the red haired instruct.

Asia sigh relaxing her body, she opens both her hands, after a minute a dark green magic start forming in Asia palm shaping into a spear like shape, Rias eyes widen seeing this but said nothing in case it will disrupt the blond concentration.

The projectile start getting bigger, few more minute pass by, Asia opens her eyes and grip the projectile in her hand "Well Asia it seems like you did it" Rias smiled looking at the spear the blond is holding but unlike the Fallen angel spear which were light color, Asia one was black color inside the spear while the outline of it is green making it looks quite sinister.

"Wow Asia-chan your amazing!" Issei praise making the blond blush slightly, "Asia I want you to throw it at the tree" Rias order making the blond nod.

Asia raise her right hand where she hold the spear and throw it but instead of it going through the tree like Rias thought it instead explode on impact shocking everyone.

When the dust clear the four see the destruction that the spear cause, it decimate dozen of trees and leaving a huge crater in the ground, "Holy shit" Issei muttered looking at the 6 meter wide crater.

'Oh lord like brother like sister I guess' Rias thought looking at the crater, "Great job Asia but keep in mind don't fire that when other are nearby alright" she said nervously, Asia scratch her head sheepishly and nods "I'm sorry Buchou"

"Akeno I want you to train with Asia, I'll take care of Issei" Akeno nods and lead Asia to a spot where they can train. Rias turn to Issei "Now Issei the problem I saw you have is that your Magic stamina is low almost pathetic and you can't completely control it unlike Asia" Rias said making the brown haired depress.

Rias see the depress expression on Issei "Don't worry Issei with some training we can increase your stamina and control" She smile, Issei looks up and grin "So how will we increased my stamina Buchou?"

"I want you to do 100 push up and seat up" Issei looks at Rias with 'Are you Serious' look, "Well are you going to do it or not!" she yell releasing some of her power scaring the brown haired, "Sorry Buchou I will get to work!"

"Buchou we're done with the exercise" Yuuto said walking towards Rias panting slightly "Ah good you two finished" "Buchou would you mind telling us what these weights are for and why it's getting heavier every time we get used to their previous weight?" he ask.

"That's what special about it, each time the weight gets heavier your speed and strength will increase" Rias said shocking the two "Yuuto I want you to swing your sword 100 time up, down, right, and left, it will improve your striking strength, even though you got speed you don't have the power to back it up" Yuuto nods summoning his sword.

Rias turns to the white haired "Koneko-chan I want you to run around the field 50 times, it will increase your speed exponentially" Koneko nods and began running. "Umm Buchou don't you think that this is a little overboard?" Issei ask doing his pushups.

"To be honest with you, all of this was Nawin-kun idea" Rias said making Issei fall on his face "WHAT THE HELL IS THE TEMEE TRYING TO KILL US" he stand up, looking at Rias "Well this is what Nawin-kun does when he is training or as he like to call it morning exercise" 'Never knew that the teme is a training freak' Issei thought.

"Now then enough thinking, get back to work Issei" Rias order making him sighs, going back to his pushups. "But wait how do you know this Buchou?" "Well it happened like this"

FLASH BACK

Akeno is currently in the club, looking at her best friend with sweat rolling behind her head. Rias bites her nail, growling, 'She is going to explode any second now' the raven haired thought looking at her best friend.

"AHHHHHHHH WHY IS HE ALWAYS LATE" Rias yell messing her hair in frustration. "Yo" As it was like magic a black flash appear showing Nawin laying on the couch, sweating slightly. Rias glare at the black haired, red aura start forming around her, she stands up and slowly walk toward the Makasha. "Where have you been mister?" she ask darkly.

Nawin looks at the red haired emotionless "I got lost in the path of life" he reply, Rias aura become more powerful hearing Nawin using one of the Anime lines, She grab his shirt pulling him near her. "I will ask you one more time Otouto where have you been… you don't want to be punished from your Ane do you?".

Nawin and Akeno sweat drop at Rias comment. 'She is acting allot like Sirzech-sama now that I think about it' the raven haired thought looking at the scene with amusement. "…The line was too long at Starbucks so I have to wait to get my ice chocolate" Akeno giggles at black haired funny excuse, Rias eyes flash red as her aura become denser.

Nawin sees the red haired gripping his shirt tighter and glaring at him harder making him sighs 'She and mom would be great friends' Nawin thought. "Fine fine I was training" he answers truthfully this time, Rias aura disappears, releasing his shirt "Is that why you're sweaty" he nods making Rias sigh "Well at least you have a good excuse but please stop being late, everyone already left doing their contracts".

"By the way what kind of training do you do Otouto?" she ask curious, taking a seat back at her desk, "Don't call me that… and my training is consisted of"

End Flash Back

"And that's how I know all of these training exercise" Rias said cheekily while Issei stare at her dumfounded. "So you're saying all these exercise come from the teme?" Rias shakes her head "Not all of them just some… believe me Issei-kun you don't want to know Nawin-kun true training… it's quite insane" the red haired shiver slightly.

Time Skip

It's been a full week already, Rias and the others are currently in the Occult club waiting for Grayfia to take them to the Rating game. Suddenly the door of the Occult club opens making the others turn to see Sona and her peerage.

"Sona what are you doing here?" Rias ask, "I came here to wish you good luck in the Rating game, also I will be commentating this Rating games since the whole underworld will be watching it" she reply walking towards the red haired. "Seems like your missing a member" Sona said noticing the black haired Makasha missing.

Rias sigh "He left a week ago saying he has things to do" she turn to Lucy "Lucy did Nawin came home at all?" "No I found a note in my room saying that he has something important to do and won't be home awhile… Mom is worried sick right now, when he comes back he is so going to get it" the blond said sighing at her protective mother.

"I see" Rias sighs rubbing her temple, the red haired turn to Akeno seeing her tired state 'She haven't been sleeping well this past week, even when I comfort her, she still worried about him, Nawin-kun is too reckless for his own good so I can't really blame her, I'm worried to'.

Suddenly a silver light appear making everyone turn to see Grayfia standing there with a stoic look "Rias-sama is time" the gremory bite her lips then nods 'Let's hope this past week of training will be enough to defeat him if Nawin-kun doesn't show up'.
