Earlier, between all the noises in the school Chiyo is separated and alone for now.
Chiyo: "He's late!"
Yamitsuki: "Give him time he will definitely show up."
Chiyo: "I'm getting tired of waiting. I wish I could just go handle it myself."
Yamitsuki: "Be patient and just wait. You now that going to fight him now will bring your downfall even if you win. Plus "He" said he would handle it himself."
Chiyo: "I know that "HIM" handling this matter is the best choice of action, but if he's too late I won't bother and just leave."
In that moment a voice was heard behind the tree where Chiyo was standing.
Unknown Person: "Why so impatient. Are you really this eager to lose again?"
Chiyo: "You're finally here I see. Your target will arrive here shortly his name is Shiro Tachibana."
Unknown Person: "Interesting name! I wonder where I've heard it!"
Chiyo: "Yes he has the same last name as the captain, but it might just be a coincidence."
Unknown Person: "I see that makes this job way more interesting. Oh and by the way how is Yamitsuki? That last fight you had shure gave him some reasonable damage."
Chiyo: "He's fine, but he doesn't need your worries."
Chiyo: "I would suggest you get to work. Your target is here."
Unknown Person: "I guess it's no wonders you lost to him. That's some crazy amount of dark energy that his emitting."
Chiyo: "Be careful because this is your only chance of defeating him since he's still unfamiliar with his devil."
Unknown Person: "That's pretty amazing. Now I am more eager to fight him. I mean defeating you is a feat on its own, but doing that while new to all this. That's just amazing."
Unknown Person: "I will need to make some preparations, but I've got this in the bag."
Chiyo: "Do what you want, but make shure to defeat him before he kills us."
Chiyo and the Unknown Person part ways and Chiyo goes to meat Shiro. He might want Shiro out, but he sees him as a reason to grow stronger and that is something he respects. After the both of them talk to each other everything else goes smoothly till the end school for today.
Shiro: "Ah, finally, I'm beat. I can finally relax, but I can't shake off Chiyos words."
Shiro: "If he's telling the truth than I need to be prepared for everything."
Kageboshi: "You're damn right for that. You need to start training so that you become stronger or else you'll die."
Shiro: "You're right, but how do I do that."
Kageboshi: "Let's head home for now there I will start teaching you."
Shiro: "Ok."
Yui: "Hey Shiro are you ready to go?"
Shiro: "Yes, Yes I'm coming just wait."
During their road Shiro couldn't stop thinking about Chiyo and how to get stronger and his expression grew Yui concerned.
Yui: "Shiro are you okay?"
Shiro: "Yes, why shouldn't I be?"
Yui: "you haven't spoken a single word since we left school! Is something troubling you?"
Shiro: "Heh,, you're really sharp on understanding others."
Shiro: "Well yes something is troubling me."
Yui: "Really what is it?"
Shiro: "The truth is that my whole body is hurting because I angered my mother and that happened yesterday."
Yui: "That's pretty reasonable, but you know more than to anger Ai last time that happened you could barely walk and I had to help you walk to school for two days."
Shiro: "Yes that's true and now I'm on edge that I might have forgotten something and she will get mad again because of it."
Yui: "Ah you poor soul (Real meaning: That was such a horrible lie once I find out the truth you're in trouble.)"
Once Shiro returned home and greeted his mother he went straight into his room.
Shiro: "Ok, now what should I do?"
Kageboshi: "Close your eyes and try feeling the dark energy in your body."
Shiro: "I can feel it. Wow that's such an uneasy feeling."
Kageboshi; "Of course it is. It's the energy of destruction itself and you currently are able to harness more of it than most newbies. Now try to channel it out of your body and give it a shape at the same time."
Shiro: "This is hard."
Kageboshi: "Of course it is it takes years for a human to learn how to use dark-"
Shiro: "Did it!" Shiro managed to manifest a black sphere.
Kageboshi: "That's awesome! You're just a human, but you managed to pick it up so easily."
Shiro: "My body is feeling weird now."
Kageboshi: "It's the side effect of dark energy. The more you channel it the more it starts to corrupt your body till it breaks down."
Shiro: "If that's the case why didn't Onimaru do anything to me?"
Kageboshi: "That's because Onimaru doesn't channel your bodys dark energy. It has its own source so your body is safe."
Shiro: "Understood."
Kageboshi: "Now stop channeling the energy and look deeper inside your soul. Do you see a bright light?"
Shiro: "Yes I do. What is it?"
Kageboshi: "It's your inherent element. If you use your inherent elements energy to create a passage for dark energy to go through you can negate all its side effects."
Kageboshi: "Now tell me, what color is that light?"
Shiro: "I don't know it looks like white?"
Kageboshi: "WHITE! ARE YOU F*CKING SHURE?"
Shiro: "Yes I'm shure you don't need to yell. Is that a problem?"
Kageboshi: "Well it's both good and bad news."
Kageboshi: "White is the color which signifies light. Which means that your element is light."
Shiro: "That's so cool."
Kageboshi: "Yes it's cooler than you can imagine. Light is basically the opposite of dark energy. It's the energy of life itself and the rarest of all elements seen only once in 1000 years."
Shiro: "Than how can it be a bad thing for us?"
Kagaboshi: "It is because light not only nullifies the effects of dark energy but it also completely erases it."
Kageboshi: "So one wrong move and instead of channeling the dark energy you will erase it and if you lose control you might end up erasing me entirely."
Shiro: "Well that's really a bad thing."
Kageboshi: "Yeah it is, but with practice you will end up mastering it and not only channel dark energy, but also light based attacks."
Shiro: "Ok then lets get to work."
While all this was going on a shadowy figure was standing outside staring at Shiros training.
Unknown Person: "The kid seems to be quite skilled, but I'll give him only two days for him to learn so our fight won't be boring. Better not disappoint me kid."
