Yuzuriha continued to wait for help that would never come as after all everyone on the planet was in the same state both her and Taiju were in. They had both been turned to stone by that mysterious light all of sudden. However, probably it would to a degree be for the better that none of her sense were working. Since while the school itself seems to be relatively free of any of the chaos and disasters happen all over the world at the moment. Statues are not good to handle anything that moves seeing as they can not move themselves.
Thus collisions and all sorts of other things were according to what would have normally been ear shot of Yuzuriha and another else at the school. But since they were all turned into an inanimate object whose still somehow retained their consciousness. The only thing any of them was darkness their old friend.
Yuzuriha after a prolonged period of time realized that apparently no one was seeming coming for them and that her fears that they were doing so because they can not be mounting. Though these were kept at bay to a degree because she had a feeling that somehow someway Senku and Taiju would do something. She was not aware of what they would do as this was beyond any of their understanding but neither one of them would give up thus why should she lose hope herself.
Thus Yuzuriha would continue on fighting in her own way to merely wait this out as eventually, she was certain to help would come for them in some form or manner. She just needs to buck down and not lose herself in the meantime.
It was mindset like this that would prove to be Yuzuriha's saving grace as not everyone that turned to stone retain their consciousness for too long afterward. Many just seemingly blackout, felt sleepy, or their consciousness just started to fade away into nothingness. The fate of these people would be unknown as there was nothing to say if they were ever still alive at that point. Could they even be saved anymore. While others were not so lucky if they did not have something to cling to as they remained consciousness eventually losing their mind as they could not handle being trapped in darkness without being able to do anything but merely think and imagine things alone.
Time pass and eventually it began to rain various parts of the world. With that, the countless statue of people that were stuck standing out outside was getting soaking wet. After all, they could not move thus they were unable to avoid all the rain falling down on them. Then there were the unlucky ones that got struck by lighting which some saw as release as once the body was broken into pieces if they were the ability to think. That went away as they could not maintain their consciousness in a piece, after all, only when they were whole was that possible. The reasoning for it as unknown as to how and why they even turned to stone in the first place.
At their school, both Taiju and Yuzuriha were getting drenched as the water poured down their stone forms. The water running down their faces in such a manner it could be mistaken as tears to a degree. Yuzuriha ignorant to all this just kept her mind activate as she thought various things here and there. Even mentally replay various series she liked from start to finish as best she could.
Though all her efforts seem to be in vain as she felt that tug at her consciousness which was starting to fade and no matter what she did there seem to be no fighting this. Trying everything she could think of to prevent from happening did not seem possible as Yuzuriha Ogawa lost consciousness. Thus leaving her truly just nothing more than a mere statue of herself. Though that seems to be the end for her, it turns out it was not as eventually, she snapped back to awareness as if nothing had even happened. Though frightening and shocking at first she just comes to a time of it as what now past as sleep for her(trying to looking on the bright side of things).
Time continues to march ever forward the petrified form Yuzuriha Ogawa was still holding on to now much large camphor tree as with no humans left to tend to it. The tree was free to grow unchecked. The same was true of their surroundings as the grass was growing uncontrollably with no one to cut it. As it once again just finished raining leaving the water to run down her stone face and her unaffected clothing have seemingly developed wrinkles and what not from being exposed to the elements for this long a time. However none of this matter to Yuzuriha who after all could not even tell what was going on around her.
'Morning Taiju' Yuzuriha thought
Mentally yawned as she imagined stretching as she did so. The idea of just thinking about moving only was not as jarring as it used to be for her. It seems like she had gotten used to the practice. After all, it kept her consciousness occupied at a time when she would get bored and was much needed change of pace every now and then
Though she had no idea what time it actually was herself, she just got used to whenever she was 'awake' like this as morning and whenever she went to 'sleep' as night time. Though she could not actually talk to Taiju this was just also part of her routine as she knew that he was there thus was acknowledging his presence even if neither one of them could do anything else currently. He at least tried to protect her so she wants to at least take that into consideration after all.
'Though at least I became a cool beauty because of this' she thought
After all, there were those that had called her a beauty before according to her friends and she was as cool as one could get as a statue of solid stone. Thus she was a literal cool beauty.
Thought like those were just one of the many that Yuzuriha would have while she was 'awake' as she did not put too much thought into her situation as panicking too much would not get her out this as that would just make thing worse. The thought of just existing in this blackness where she was still conscious but that was it. It could be very terrifying if she let it get to her. So she just was trying to not let that happen as that was seemingly possible because she was aware that she was not alone and that someone else was here with her. Feeling sleeping as again she was not really aware of what 'sleep' meant for her in this state but that was something she did not put too much thought into after all. For a similar reason to when dealing with her being 'awake'. Cycles would come and go and Yuzuriha would not be aware that they were shortening over time. The time she was 'awake' would be shorter and shorter while the time she was 'asleep' would become longer and longer over time.
Time continues onward around them as they were both unaware that this had not just been them alone as Yuzuriha even all the time that had passed since that fateful day still thought that it was not possible that just everyone on the planet was affected. She hoped that those effected like them were being examined to see if there was a way to free them in a safe manner. Though she also wonder if she was on display somewhere either as a display piece in an art museum or standing a self monument to herself and all those that unexpected turned to stone one day.
Since everyone was in the same basic case as Yuzuriha the chaos that happened on that first day was not fully over. The immediate chaos was and had been for long time now though the secondary effect of their being no humans to maintain their structures was starting to rear its ugly head. Unlike the time of old where the thing that could last would and for thousands of years at that. There were many things built by modern man that if had up kept would fall to ruin and thus that was the case with various damns around the world after countless years.
Yuzuriha was already basically more 'asleep' then she was 'awake' at this point. Being awake was something that happened only seemingly once a week now and even then it was only for a few minutes before she would fade back into her 'sleep' state. The school itself had already been overcome by nature as there was nothing to holding it back now as things like weeds, grass, and what not was growing all over the place and everywhere.
Both her and Taiju's uniforms were starting to show clear signs of wear and tear as they were constantly being exposed to the elements unlike those that were still within the school. The lights might have been dead for years now but those inside the school still were somewhat sheltered from the elements thus their clothing was still in more a prime condition then those stuck outside like Yuzuriha and Taiju.
Though that all changed when the damns broke from now being tended to by anyone. In fact, things were made worse as animals that were like those birds she found days before that very same thing happened humanity. They made their homes in a place that they would have been allowed to otherwise thus various things that could go wrong as the result did. So various area got flooded and flowed throughout the world and their area was no different. A surge of water came rushing through that toppled buildings and rushed over the city with nothing to stop it now.
So this was when Yuzuriha and Taiju were separated as the flow of water was not enough to dislodge Yuzuriha from the camphor tree she was holding on to. Although Taiju just standing there was not as lucky as he was washed away by the flow of water to somewhere else leaving her there alone without even being he was gone.
