The afternoon was buzzing with crowds as Karma and Nagisa stroll around the mall. They stopped at the antique store to bye things considering they've been bored on weekends.

" Karma-Kun look at this! " Nagisa said as he run to an area with plush keychain accessories. He's holding an octopus keychain. " This looks like Koro-Sensei! Hm, I wonder if there's a yellow one. "

Karma almost broke his expression as he snort. ' If he see this that smiling octopus would be beaming all over the place. ' His smile then turn to a frown. " Karma-kun? " Nagisa's voice broke out his thoughts.

He shake his head as he walk to the blue-haired male. " Hm? "

Nagisa nervously scratch his cheek. " Well, I wanted to ask you, remember that I want you to acompany me? I don't know what to give for my students, for months they've been trying to keep me unguarded since I told them to try surpassing me with assassination skills and tries to suprise them for their hard work. "

Karma blink before bursting out. " HAHAHA- oh wow, thank you for trusting on me then! " He place a hand on the confused male. " I was suprised that you were not hanging out with your little kids that I'm worried. Besides, not sure that I'm cut out to be the gift person, have you ask Kayano? "

Nagisa tilt his head. " I did yesterday but she was busy working on a new movie. " The red-head nod but soon stop as he spot something behind Nagisa. With a glint in his eyes he walk to an isle with toy guns.

" K-Karma-kun? What are you doing with that?! " Nagisa felt nervous when Karma lay hands on the toy guns, now it was all on his arms.

" What's wrong in gifting them something that helps on assassinating? " Suddenly a shadow cover his face. " This would be great practise, remember the time when Koro-sensei step on a net trap and got stuck above, enough for us to hit him and golly- his face is priceless!! Besides this brand is flawless, getting hit would be fatal!! "

Karma's devilish laugh got Nagisa to sweat all over. " Y-Your telling me I have to be caught in that same situation? " He's not like Koro-sensei, not fast to dodge those bullets even when it's just toys. But mabye it could be good practise.

Nagisa then smile nodding. " I guess it would be fine to let them have guns like those in recess times and mabye class times too, let me just look for plushies for the girls. "

" I remember he said about ' Sweets or any cooking made by a man can warm a girl's heart '. Try that, but make sure not to be a full of yourself. " He chuckled making Nagisa blush.

Before the two of them finalize on their items, Nagisa was about to return the keychain but Karma stop him by grabbing his arm. " Now, what are you doing? Don't you want this? " Nagisa stare at him for a moment. " Do we have enough money to pay all this adding the keychain, it's not that important. "

Karma shake his head. " Allow this to be a gift from me on inviting to go on shopping. It was really unexpected that I wanted to try doing this with you, how long has it been? " Nagisa's eyes went to a daydream state. " How long? It's been long huh. I guess I could buy this, thanks Karma-kun, will you pay this though? "

" Any to waste some money for this thing? " He swing the keychain. " Of course! Even the littlest of things can bring such big memories. " He smiled a bit fondly making Nagisa smile softly. " I'm glad, that you still hold the memories to cherish Karma-kun. "

" Glad to see you proud, now why don't we stop at the cafe, your arms might be tired of buying all this later. " Nagisa nod. " Sure!! "

They both then went to the counter. It was a rather nice feeling Karma has been holding the moment he met Koro-sensei, it teached him that every memories should be cherished, even the bad ones.

Nagisa was taking it greatly, he was very fond of his teaching more than him and also became a teacher because of that yellow octopus. Karma wondered, there can't be any job fit for Nagisa other than assassinating but he didn't mind, it was his choice. Thinking those past also brings him a past way before those. The time he'd been betrayed by a teacher.

The red head shake his head again. ' Welp, it's all in the past isn't it? No other way to bring it back. ' He look at Nagisa standing infront of the counter and now returning with plastic bags of toy guns. Karma chuckled at the blue head's difficulty. He lay a hand on Nagisa's hair.

" You still have a hard time with your muscles Nagisa-kun? "

Nagisa pout making Karma laugh even more but soon smiled sighing. " Okay, come on help me carry this, it's too heavy!! " " Alright alright~. "

" Hey Karma-kun? " " Hm? " Karma turn his head to Nagisa. " Y'know, I was thinking, do you mabye want to visit my class? "

Karma smirked. " Oho~. Is that all your asking me or something else? " Nagisa sighed again.

" Well, mabye you can help and guide them properly on training. I'm not really a good teacher on combat. " Nagisa scratch his cheek, giving a side glance to the red head who smiled sadistically. Oh no, he awaken the monster.

" Oya~? Never thought you could ask me that? Being a teacher? Thank you Nagisa-kun~ now.. " He bump his fist with a devilish grin. " How do you want me to teach them? "

Nagisa sweatdrop even more, he can picture his class screaming in deep sorrow by the hands of that devil. ' I pray for you my students. '

' Fufufufufu~. '

_____________________________

The two best friends talk to eachother blissfully as they head to the cafe. But they didn't notice a running thief going to their direction. It was sudden, as Karma and Nagisa was nearing to the glass door at the entrance of the cafe, Karma spot the speed and immedietely take hold on the thief's hand making the man sweat.

" W-What are- get off of me!! " Karma tilt his head, his eyes scroll to the purse the man has been holding, it's obviously from a female by the design and size. He tighten his grip squeezing the thief's hand. Nagisa run to him and turn to the thief. He quickly grab the purse from the man's hold. " Who owns this? "

" It's mine!! " The two including the people close to them turn to a woman who's running. As the woman notice them holding their purse she immedietely bow. " Arigato!! For bringing back my purse. " She glared at the thief.

" You snatcher!! You should be in jail for this!! "

The man scared for his future wiggle around making Karma lose hold of him. The thief then snatch a knife from his pocket and point it on both the boys.

" STAND BACK!! I'M NOT AFRAID TO USE THIS!! " Nagisa began to sweat a bit as he glare at the thief, Karma didn't hesitate to take a step forward making the man even more afraid clearly interested on the outcome.

" Y-You.. I SAY STAND BACK!! OR I WILL KILL YOU!! " He yelled making the boys smirked. Karma scoff. " Have you ever killed someone mister? "

The man gulp, his hands shake. But the thief then aim the knife to Karma's direction, Nagisa reacted by running infront holding the knife's handle sturdily. Karma smile at the action and wave it at Nagisa. " Arigato Nagisa-chan~ But I can handle it y'know. "

Nagita huffed. " Don't be too cocky Karma kun. " Karma just stuck out a tongue at the threatened thief. The man smirked letting the two be wary. " NOW!! "

Fast footsteps pace towards them, Nagisa turned first then suddenly his eyes go wide. " KARMA LOOK OUT!! " Karma flinch and turn but it was too late.

" Ngh-!! "

Karma's brows furrowed as he grab the handle that has been squeezed even further by another man. " A-An accomplice.. what cowardice.. cough!! " The other man pull back the knife hashly as Karma's legs shake.

" KARMA KUN!! "

Nagisa trembled. This can't be happening. Karma grab hold on the floor as he try not to collapse, damn, he stab on the body's weak parts, he's body system will soon shut and he'll die not too long. The police came and grab the two thieves as Nagisa run to Karma. He take off his jacket to cover his wound.

" You'll be okay!! Let's wait for an ambulance, you'll live but be unconscious for a while!! "

He support Karma's body as he flinch. It was too late, why? Karma's head began to spin. He didn't want Nagisa's expression to be the only view for him to see before he close his eyes. He wants to smile. He wants Nagisa to smile. Because of him being the one to stab his favorite teacher, he wants Nagisa to feel great. Karma blew that chance.

" Hey.. don't worry, I won't die so easily.. if I were.. don't be so hard on yourself..not your fault cough!! " He spat out blood to Nagisa's horror. " No.. " Luckily the fellow nurse and staff brought some supplies for Karma until the ambulance arrives.

Nagisa didn't want to explain out the obvious, Karma is going to die, really going to die, it was like a dream, a thought that it was too impossible to happen and now it did. Right now, he's witnessing his best friend about to leave this world. It was his fault. It was his fault he wasn't any faster, to warn him properly, now he's going to live the guilt and blame himself for everything.

" Hey.. " Nagisa immdedietely turn to Karma who smiled painfully. " Don't frown like that cough, it'll only worry the others, smile.. for your students....for Kayano...for Koro sensei...for me cough!! "

" H-How " He stuttered but Karma just gave him a smile, Nagisa has no choice but to smile back, it's better to grant a wish before he dies, it's only fair.

It's not fair.

Karma wish to go back time for he wish not to die either but then he doesn't because that would be a waste of a lesson for his friend. He needs to move on but he felt hesitant to leave this world.

" Why? To die.. so pathetically.. " His vision began to blur as he slowly close his eyes. Nagisa poured to tears. " KARMA-KUNNN!!!! " He held a shaky grip on Karma's blood soaked shirt. He's not ready, he was over on koro-sensei's death, he doesn't want to suffer more.

It's not fair. But life's never fair.

' Go.. teach them..Nagisa, isn't it your plan, don't disegard it now. It's your dream, make them winners, make them feel special. To assassinate and please. '

____________________________

Silence erupt through Karma's ears, he can feel himself conscious even when he didn't open his eyes. Did he survive? How? Where is Nagisa? Is he safe? He grunted as he slowly open his eyes. White? Is he in the hospital? He sat up, all around him are just plain white? Where is this? Is he dead? Karma stands up with so many questions in his head.

" Ah, your finally here, took you long enough Karma. "

Karma's breath hitch. That voice.. he slowly turn around, behind him.. a man with wavy black hair stood. He wore a small peaceful smile as he stare at Karma's eyes with his big black ones. Karma didn't hesitate to run over and hug the man for he knows who he is.

The man was taken back as he was dragged down on the floor, the red head now clinging unto him.

" Oof!! Damn, kid you've grown too much. " The man chuckled. Karma's lips quiver. " That's what Nagisa says too. He's already reach his goal, he's become a teacher to teach the Class 3-E. "

" Your happy for him, why are you sad? Is it because you are not alive anymore? " The man ask. The boy above him shake his head. Karma can't mask his face as tears fall from his eyes. " No, it's because.. I'm happy to see you again.. Koro-Sensei. "

The man smiled. " Don't call me that, I'm not your teacher anymore. Call me Ryushi Korogane. " Karma's head plop to his chest shaking his head. " No, your Koro-Sensei. "

" Stubborn child. "

The man laugh again as Karma listen at the pleasant sound. He peacefully lie on his chest feeling the man's stomach going up and down. How he miss to hear his sensei's voice. " I can feel you, I can feel my own heartbeat too. Am I alive? Are you alive? "

" Try feeling my heartbeat, I'm no longer alive since the day before you kids graduate. You know I'm already dead Karma-kun, Nagisa killed me infront of you. " Karma's rise and look at him with a bewildered look.

" T-Then why.. I can feel you. " He feel his sensei's soft hand rubbing his head, the man smiled fondly. " Glad to see you finally opening up yourself. I don't know why your alive. "

' H-Huh? ' Impossible, he's still alive but the soul of his sensei is with him, touching him, fondling him with love. He felt a bit nervous what will happen to him next.

" Don't worry, your not going to hell. You see I was resting here in this white place to wait for you. " Seeing Karma's reaction he continued. " Someone told me, that I would see you again, I cleary didn't understand what she truly meant but here you are talking to me. "

He then look at Karma. " You will live again. "

Karma can only stare at him with pure disbelief. " Why..though, I didn't do much when I was alive. "

" But I see your potential. " Koro-sensei sat up and pat Karma's head. " If I'm given that choice I would probably decline becaue of my past failures, you are still young, not too young but needs something to make you see more than what you see currently. "

It took time for Karma to talk. " What do I do? " Silence echoed through the place as Koro-sensei smiled.

" Why are you asking? Beats me. "

' Ugh-!! '

" O-Of course, right, gomen sensei.. " Karma sheepily smiled slightly. He can feel the nostalgia of being a student of this man. If only.. it would go back time. But then it would be a waste.

" Remember, I will be with you, including with the others of course. Don't forget my teachings Karma-kun. "

karma nod silently making the male stand up, with a last glance he walks away.

' I'll live huh.. this brought so many questions, but I promise sensei, I won't waste any opportunity. ' He grip his palm. ' If he said it's a great chance for me to shine then why not accept it. ' " I choose to live again. "
