Doom System In BNHA

" ... are you okay!?"

"* Ah, f.u.c.k my head feels like it's about to explode... -- Huh? Who's screaming?*"

Opening his eyes, Natsuki's worry stricken face was the first thing Sei saw. Shaking his himself awake, he was soon helped by Natsuki who shook his entire body.

" Young Master!! What's wrong, speak to me!"

Unable to withstand her violent shaking any longer, Sei reached out and grabbed both her shoulders.

" Natsuki I'm fine, but please stop shaking me, can't you see my ar- Eh?"

Only after looking at the stunned Natsuki did Sei realized his arm was fine. Thinking it must be due to a temporary adrenaline rush or maybe the drugs. Sei tried to move it some more but no matter how much he did he felt no pain.

" My arm it's fine... It doesn't hurt anymore."

" Sei, your arm it's healed... How?"

Raising his head, he didn't know how to answer that question. Should he come clean about his true origin and the existence of the System. Quickly getting of that idea Sei got up from his bed and ran to his restroom. After closing and locking the door, Sei went to the sink and washed his face.

" That really happened. My previously broken arm was completely healed. That ability really worked, I finally have a Quirk... I can continue chasing my dream, I can become a Hero!"

Taking a towel and wiping his face, two knocks sounded at the door.

" Sei, what's happening!? Talk to me, please... "

Natsuki wasn't able to finish her sentence when the door opened and Sei hugged her.

" Sei. What are you doing...?"

Confused by what was happening Natsuki was about to push him away but before she could Sei released her. Now facing her, Sei finally managed to speak the words he knew he should've said much earlier.

" Natsuki, I'm sorry. For everything I've put you through these last few years. You didn't deserve any of it, can you ever forgive m-"

This time it was her who embraced him while whispering her response into his ear.

" Of course, Young Master. No matter what I will always be by your side."

" Thank you. Then can I ask you a small favor?"

He asked her as they separated from each other.

" Does it have anything to do with your now perfectly healed arm?"

Not trying to say anything uneccecary, Sei simply smiled wryly at her. Sighing and shaking her head Natsuki eventually agreed to at least listen to the favor.

" Could you find out what exactly I need to do, to become a Hero?"

As soon as those words left his mouth, Natsuki's mood instantly turned gloom. She was aware that Sei dreamed od becoming a Hero, but thought he had come to terms with its impossibility.

" Young Master, I'm not sure how exactly you managed to fix your arm, but to become a Hero isn't so simple. You'd first have to enroll in a High School with a certified Hero Program, and then Graduate from said school. Several additional steps would then fallow after those two."

While he was listening to her response, Sei was simultaneously changing clothes. So when she finished talking he was already waiting by the door.

" Alright, could you to find the school with the best Hero Program and enroll me in that school?"

" Well that would be U.A. High, but enrollment must surely have come to an end-"

" I'm sure that can easily be solved by making a generous donation to the school board. Oh, I'm heading down to jog around the garden, meanwhile could you hire me a trainer?"

Before she could reply, Natsuki saw her heavy young master rush out the door. Seeing him in such high spirits she decided to not tell him about the recent call she had with his Mother.

" But a trainer? For what exactly?"

--

As Sei finished his jog he was approached by Natsuki and a very tall and muscular man. Guessing this was the trainer Natsuki had found he politely went to shake the man's hand. He soon was informed that this was not going to be a fun experience in the slightest.

" So this is the chubby kid I'm supposed to train? -- Sigh -- Run three l.a.p.s around this entire estate and don't even think of stopping. I don't care If you finish the l.a.p.s crawling but no stopping."

Flabbergasted by the man's sudden order Sei turned over to Natsuki who looked away.

"* Did she do this on purpose?*"

" Did I stutter boy!? Run!!"

Hearing the man's shout, Sei didn't waste anymore time and started running. Although at his current size wasn't all that fast or graceful foe that matter. Yet once he was sufficiently far away, the hardcore drill instructor became much more mild. Turning towards Natsuki he even got on one knee as he addressed her.

" Big Sister, are you sure about this? His body is hardly in any shape to successfully finish even one l.a.p, much less three. He could very well collapse from exhaustion... "

With her eyes fixed on the direction Sei had run off to, Natsuki ignored the man's question. Leaving the man to awkwardly remain kneeling not knowing what to do.

" Guess I'll just... "

" I didn't say you could get back up."

" My apologies... "

--

Two hours later, Sei who was drenched in sweat and breathing heavily was barely holding up. He was currently on his third and final l.a.p, but could hardly move. His entire body was in pain and his mind was muddled leaving him barely functiable.

"* Almost there, I'm almost ther-- F.u.c.k Me!*"

Although his mind was still set on completing the final l.a.p his body wasn't. Collapsing on the ground, Sei struggled to get back up but his arms gave up on him also. Left with no other choice, he used his head to drag himself forward.

"* I can't give up. I've already done that twice, and I'm not going to make that mistake a third time. No matter if I have to forcefully drag myself, I will finish this l.a.p. No matter what!*"
