[Aoyama Gakuin Highschool]
Of course in this very moment Kaido was standing infront of his current to be class together with Aileene
On the other hand the other class were looking between Kaido and Ayame after what they saw a few days ago on the school stairs
Naturally the blonde guy was also in that class as he glared towards Kaido naturally was hostile at him due to his relationship with Ayame
Last week due to the incident Ayame was then asked about her relationship with Kaido, unexpectedly she then answered truthfully that Kaido was her boyfriend that went missing for about a year
Hearing that relationship all kind of messed up scenarios was then thought up by the class which became the current topic for all
In their impression of Kaido all they can think of was that he had a bad boy vibe with him, while Aileene had her mysterious charming side
After being called out by his current instructor for this school Kaido then introduced himself to the best way he can do
"Uh! Names Riruko, Kaido... I'm 19 yrs of age and that about it"
On the other hand Aileene said
"My name is Aileene! I'm a foreign citizen, thus I'm only introducing my given name"
Of course since she doesn't have a surname she then didn't reveal this fact towards everyone present
Hearing this their instructor then gave out a few words of introduction that such students were permitted to join the class during this time of the year and with the consent from the principal
After that they were then asked by the various class which started from Aileene
Due to curiosity they then asked
"Hey! Are you really Riruko's sister?"
Hearing that Aileene kindly replied
"Nope! Were not blood related but I thought of him as such"
With that they then turned towards Kaido as they asked
"What about you? Are you fine with her answer? After all she is quite charming and beautiful, it won't be long till someone chase after her and get her from you"
Expecting some kind of drama from them, Kaido then bluntly replied
"Her? She has her life of her own, if she wants to go then go away, I'm not stopping her"
With that the males other class then went into an uproar as they glanced towards Aileene with little bit expectation
Soon after the various questions which was asked by the class, the instructor then advised both of them to take the farthest seat at the back
Not long later the class then started which goes off towards the first subject which was history
Since Kaido wasn't much interested in such topic he then ignored the whole lesson while thinking about his next scheme that he will play in case the organization decides to attack him in a secluded place
After what seems like awhile the class then ended as each goes on to their way
Unfortunately since both Kaido and Aileene caught everyone's attention, they were then barraged by the second batches of questions which were filled with hidden meanings
Pushing Aileene to answer all of that for him, Kaido then left the class as he goes towards the washroom, but before he could go out of the room the blonde guy then suddenly blocked his path

"Hey! Your kaido right? I'm Aoki"
"....."
With that silent reply Aoki then continued
"Seems like your relationship with Ayame was a little bit sour"
At that moment Ayame stood up from her seat while glaring at Aoki, as for her two friend, they immediately tried to call him out
"Aoki!"
"This is not your problem! Don't meddle on this"

Hearing that Aoki then ignored them as he glanced at Kaido
"Then with your behavior towards her, I can expect that I can literally steal her from you... after all with my connections and wealth I can make her happier than being with you"
Hearing that Kaido then raised a brow before scanning him
After all he didn't mind whether Ayame is with someone else or not, since he doesn't have a memory with her, but since such a guy was somewhat belittling him he couldn't help but react to such provocation
After Sighing in dejection Kaido then replied
"Am I supposed to be impressed?"
Hearing that monotone voice everyone was then shocked
"You say that with your connections and wealth you can make such a person happy? What can your wealth even do? Buy stuff? Hire men? Order someone? Guess what pea brain do you even have enough money to protect yourself from me?"
"!!!"
With all of the attention towards them Aileene then glanced at the situation before enjoying the show
"Im not intimidated stupid! You can bring as how men you can get to try and suppress me but I can advise you one thing, only few of them can actually hurt me!"
"You ignorant rich boy brat that doesn't even know how big the world is, do you think your wealth can help you live safely in this godforsaken world? You must be joking! You parents must have riddled you with lies"
"With your wealth and connections infront of me, all of them are as good as non-existent, imma say this now and I won't say it again douchebag! Your nothing but a mere ant to me... hear that? An insignificant insect"
Upon saying all of that the whole class then became silent as they eyed such a scene with complete shock in their eyes
Even Ayame was silenced by all those words that Kaido threw towards Aoki
Bit before they could react the next class instructor then entered the room and calmed the whole class
Seeing that Kaido suddenly grumbled for him to unable go to the washroom as he patted him while saying something before settling down
"Think again who's your messing with asshole!"
*********
After that incident, the time then passed normally as if nothing happened in between Aoki and Kaido early this morning
Even when they were on break, they would rather ignore each other for awhile
Of course since Kaido was new at this school, someone would naturally be selected by the instructor to guide them around to get familiar to the surroundings
This time he's together with Aileene as they roamed about while getting some unneeded attention from the other students of the school
After some time of roaming both Kaido and Aileene couldn't even find the trace of their target, causing both of them to feel something was amiss, due to that they then headed towards the faculty right after roaming the campus and was immediately notified that their target hasn't gotten back yet
After getting informed by that situation, both of them somewhat felt at a loss of what to do, causing them to return to their class in boredom
Luckily the next class was about scientific elements structure, which was somehow memorized by Kaido during his time of being imprisoned
At this moment the instructor was somewhat teaching about how the elements works and about their specific details such as acidity levels of each element
Coincidentally he was also teaching them earnestly while breaking down every function of such said elements
Right this moment the instructor then started a question which caused the whole class to tense up, since everyone in this class knew that the instructor that were infront of them would occasionally ask some unexpecting students to know whether they are listening to his lessons or not
"Now class can you tell me, what is the most radioactive material ever known and the most toughest material ever known?"
With that the instructor then scanned the whole class as his eyes landed on one of the smart diligent person in class
"Aoki! Answer this question"
Hearing that all the people inside the class looked towards Aoki with all attention concentrated on him
Hearing his name being called, he then stood up from the crowd and answered calmly
"My answer is nuclear radiation and diamond, after all both of them are known for this aspect"
With that the instructor then nodded when suddenly out of nowhere someone them interjected him
"It's Lonsdaleite and Polonium!"
At that moment everyone then turned towards Kaido who suddenly answered the question
Hearing that the instructor then leaned on the board as he asked
"Is that so? Then please tell me your reason why"
With that permission Aoki then glanced towards Kaido as he snorted and said
"Diamond is a superhard material is a material with a hardness value exceeding 40 gigapascals (GPa) when measured by the vickers hardness test, they are virtually incompressible solids with high electron density and high bond covalency"
"They are the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and ellectrically insulating properties, and much attention has been put into finding practical applications of this material"
Hearing that Kaido shook his head as he denied that idea and pointed out his own hypothesis
"Lonsdaleite is now a rare natural substance looks likely to leave them all far behind – at 58 per cent harder than diamond, with its title of the "world's hardest material" to man-made nanomaterial some time ago"
"The first, wurtzite boron nitride has a similar structure to diamond, but is made up of different atoms, The second, the mineral lonsdaleite, or hexagonal diamond is made from carbon atoms just like diamond, but they are arranged in a different shape"
"Only small amounts of wurtzite boron nitride and lonsdaleite exist naturally or have been made in the lab, so until now no one had realised their superior strength. The simulation showed that wurtzide boron nitride would withstand 18 per cent more stress than diamond, and lonsdaleite 58 per cent more. If the results are confirmed with physical experiments, both materials would be far harder than any substance ever measured"
"With that diamond might as well be a paper infront of it"
Hearing that the whole class was then silenced as they looked towards Kaido with somewhat a complex look, after all they didn't expect that answer from him at all
But that didn't make Kaido flinch at all as he continued
"And what? Radiation from a nuclear plasma is the most radioactive material on earth? Just because of what? Cause of uranium?"
Hearing that remarked Aoki suddenly answered him while glaring at him, in all his life never had he been humiliated like this before
Naturally he would stand out of class by sharing his insights, so even if he is wrong then atleast he could be considered one of the diligent students
Unfortunately Kaido ruined the atmosphere due to his remark and publicly made him look like an idiot
"Yes nuclear energy is the most radioactive material on earth!!!"
"On what ground? Is it because your elementary teacher told you so?" Asked Kaido
Gnashing his teeth Aoki answered
"No! The emission of these rays is called nuclear radioactivity or simply radioactivity. The rays themselves are called nuclear radiation. A nucleus that spontaneously destroys part of its mass to emit radiation is said to decay (a term also used to describe the emission of radiation by atoms in excited states). A substance or object that emits nuclear radiation is said to be radioactive"
"the radiation is found to be associated with certain elements, such as uranium. Radiation does not vary with chemical state—that is, uranium is radioactive whether it is in the form of an element or compound. In addition, radiation does not vary with temperature, pressure, or ionization state of the uranium atom. Since all of these factors affect electrons in an atom, the radiation cannot come from electron transitions, as atomic spectra do"
"Nuclear radiation has energies of the order of 106 eV per event, which is much greater than the typical atomic energies (a few eV), such as that observed in spectra and chemical reactions, and more than ten times as high as the most energetic characteristic x rays"
After hearing all of that everyone's eyes then focused towards Kaido as he said his own hypothesis regarding Polonium
"Thats true but Polonium is a rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. Due to the short half-life
of all its isotopes, its natural occurrence is limited to tiny traces of the fleeting polonium-210 (with a half-life of 138 days) in uranium ores, as it is the penultimate daughter of natural uranium-238"
"210Po is an alpha emitter that has a half-life of 138.4 days; it decays directly to its stable daughter isotope, 206Pb. A milligram (5 curies) of 210Po emits about as many alpha particles per second as 5 grams of 226Ra. A few curies (1 curie equals 37 gigabecquerels, 1 Ci = 37 GBq) of 210Po emit a blue glow which is caused by ionisation of the surrounding air"
"About one in 100,000 alpha emissions causes an excitation in the nucleus which then results in the emission of a gamma ray with a maximum energy of 803 keV"
"More can be said about such evidence that Polonium is the most highly radioactive material on earth, its just saddening that your little brain couldn't handle it"
With that Aoki was immediately silenced followed by the clapping sound of the instructor
"Looks like you've done your homework, are you homeschooled?" He ask
"Nope just everyday hell like torture of knowledge intake"
With that the whole class then returned to normal as the instructor continued his lesson
Unfortunately the whole class was looking in between of Aoki and Kaido, especially for Ayame as she clearly saw and heard one of Kaido's experience during his disappearance
Due to that she then clenched her fist as she waited for the class to end
After for what seems like forever, the class then ended as everyone begin to set off from their class and return to their homes
Some even invited others to go to other places, while some attended their clubs
At this moment Kaido was now preparing his stuff to leave while having Aileene wait for him on the side, but before he could even take one step to get away from everyone, Ayame then somehow called out to him which caught everyone's attention
At this moment all speculation rose in their minds upon their interaction, some even looked towards Aoki's table to see his shocked reaction
In this class everyone knows that Aoki likes Ayame, unfortunately the latter has some kind of unresolved relationship towards Kaido, causing everyone to get excited for this interaction
"Kaido!"
"Huh?!?!"
"Do you have any free time to talk?" She asked
"I have free time! But not on the part about talking to you" replied Kaido
"I just want to talk, can you even grant this just for me?" She urged him
Seeing that Kaido turned towards him as he said
"Look i don't remember who you are or what our relationship is in the past, but one thing for sure is that somehow you are annoying"
Afyer that Kaido glanced away and was about to leave, when Ayame suddenly said something toward him
"You said that you'll return! That's why I waited... all this time"
Upon hearing that some slight fragments of memory flashed by his mind causing Kaido's mood to sour
Charging towards Ayame he then raised up her wrist as he tried to tighten his grip on her
"You've got 10 minutes to explain everything to me"
With that he then pulled Ayame towards the roof to have a private conversation with him
