God succession system

When Alex heard her words he momentarily blanked, and thinking of Koneko growing thought of the light novel dxd image of her in what was "shirone mode". He was curious about this and asked,

"What do you mean growth spurt?" Kuroka shrugged and answered,

"I'm sure you noticed how shirone looks underdeveloped, she would likely go through a late normal growth spurt within the next couple years, but due to the stimulus she received here it triggered early, nyan. As a result her physical body and powers will take a leap over the next week or so, and she will end up going into a mating season a couple time due to the hormones in her body, but by the time it finishes she'll look her own age or even maybe a little older, nyan." Alex nodded when he heard her words, and thought about her future body that wouldn't lose out to even Rias. He then recalled something else Kuroka said,

"Wait she'll still go into a mating season?" Kuroka nodded and explained,

"When we go into a mating season regularly we simply want to mate and create offspring, it can be controlled when we get older, but in this case I can't do anything about it because it might effect her growth spurt, nyan." Alex rubbed his temples when he heard her words. He recalled that even Kuroka knew that Koneko's mating season was bad for her body originally, and was the one who helped her during it. If she said she can't do anything about it she was telling the truth. She seemed to notice his concerns and smiled before saying,

"Don't worry, I'll be here to help her control herself somewhat, Nya. Besides you should be happy, after this you'd probably get to enjoy both us sisters together, nyan." Alex smiled bitterly at her words, and said,

"I'll probably still wait for her to at least get into her second year at school, but at least now we know she'll actually grow." His words were in reaction to the series, as she didn't even grow after knowing issei for over a year, even though she was supposed to be so different in her mature body. Then again it might've just been the writer wanting to keep a young looking girl around.

After the discussion was over, contrary to her earlier words Kuroka then jumped him, and the two were joined by Rias not long after.

Over the next couple, days Kuroka stuck to Koneko like glue, and Ophis stuck to Alex the same way. He didn't let it bother him, as long as she didn't pick up strange habits from the girls. By this time it was obvious to everyone there was something up with Koneko, and several times Kuroka would randomly take her out of the room, presumably due to being in a temporary mating season. As her time at the dorms lengthened, everyone also started to realize that their earlier opinions about Ophis were off the mark, and she was actually just very pure, and naive.

"Want some candy?" Alex asked as he held out a lollipop. Ophis took it and placed in her mouth before saying,

"Thanks." And they all looked on in amazement as the dragon God, leader of the the terrorists, their enemy, sucked on a lollipop and played a game with Alex. Irina and Asia also seemed to understand Ophis's personality, and started to act normally around her as well, playing cards and such with her. As this went on Akeno and Kiba focused on their studies for the test in less than a week. Alex was wondering if he should worry about the attack during the test, and had Rias and Kuroka meet him in his room.

"I know I don't share events that I know about, but his time I'm gonna break that rule." They looked at each other in surprise and became serious. Alex then started to explain,

"After the mid level test, the hero faction led by Cao Cao are most likely gonna attack us using Samael. With this they'll try to steal Ophis's power and take down me and Vali." When they heard his words both girls started emoting a slight killing intent, until Alex waved them down and continued.

"After that Shalba will show up again and initiate a high level terrorist attack on the underworld. I'm not telling this to you so we can prevent it, but so that we can answer the situation properly when it happens." They sighed and nodded at Alex swords as they both understood what he was worried about, if they actively started changing events then it might change it so that instead of say one person dying several people died. He wanted to keep things as predictable as possible. Rias then asked,

"So do you have a plan for samaels poison?" Alex nodded and said,

"The meditation method Wukong taught me is supposed to help maneuver and remove harmful substances, as well as replenish ki, it should at least help me fight the poison until I could get someone to help me." He also had one more training session with Wukong before then, so he planned to learn more about that method during that time. The only problem he could think of was if Ophis wanted to watch him train with Wukong as well.

Like this they spent the rest of time before the test getting ready in their own ways. Thankfully Ophis understood when he said she couldn't follow him to train with Wukong, and spent the time with Irina and Asia instead. When he returned after a "couple hours" she could tell his aura was a little different though and grew even more curious as to how he changed even that much so fast. Like this the day of the promotion test finally arrived, and surprisingly the biggest issue that morning was the changes in Koneko.
