Reborn Into The Seven Deadly Sins World

'Another10 years passed, now my body is big enough to be called a 15 year old kid, but...my face is still too childish! It's so weird when I look myself at the mirror, a face of a 10 years old kid on a 15 years old kid body, without muscles of course...its simply too strange, people can't guess my age at all!'

'Also, thanks to my passive regeneration as a vampire I can train my body at my limit, even If my bones broke or my muscles rip I will be fine in less than an hour, actually, this regeneration is too convenient, even when I'm tired, I just need to rest for a little while and I will be at my peak again in no time! Maybe healing is even correlated to aging...'

"C'mon brat, let's go home, what are you dozing off?!"

"Eh? Ah, yeah, old man"

"Stop calling me old man will y-"

"And stop calling me brat! I'm already 15 years old!" (Actually much older)

"Tsk Tsk"

With the sound of cursing in the way home, Leo thought again his almost 10 years of training.

'My body now Is able to withstand a lot of blows without even being scratched, and when it happens, I regenerate...oh, I meant bears blows, not human blows'.

'My strength is so high I could destroy a rock big, like, ehm...5 meters? 10 meters? I don't know, the perception of the world with such a tiny body is all messed up, it's even too strange viewing humans bigger than you, all the thing seems bigger with this body... also, anybody would never guess this tiny body can have such a horrific power!' ( He is still rather small, not too much, but not too tall either)

'But my strongest weapon in the arsenal is my speed, when I was 5 I could run much more faster than a human, now I'm much more faster than a horse...it's terrific! And I have almost endless stamina thanks to my regeneratio-ehm, I already said that. Oh, also, now I can 'have' claws, I mean, I just have to thought about it and claws will grow at my fingernails, I can also undo it. These claws are powerful enough to pierce through wood like buŧŧer and rock like rotten wood. Heh, vampire power, boy.'

'Speaking of weapons, swords are actually pretty cool, from all the possible wielding weapons I used, the sword is the only really 'true' weapon I could use 'freely', it's just like a connection between me and the sword, I can't describe it well...all that's is thanks to the old man's job, he is the elite of this city, and the personal guard of his majesty, the king...despite being unable to use magic, he is so strong, magic users can just lick his feet...oh, the name of the old man is Judd, don't know his surname, probably I'm never gonna ask him though.'

'I also asked to the old man to do a traing session for me, since I'm a complete amateur, and after verifying my overall body, he laughed loud and grinned to me, saying: "Kiddo, I don't know why your body is so strong, actually, I don't give a damn at all, it would just be a waste to not rise your potential." And so my training session begin: Being able to localize a specific, small, object in the jungle, fighting with more tigers at the same time with a hand and no weapons, being able to hide your presence so highly normal humans would find difficult even if you stand right beside them, being able to analyze your opponent by their weight, height, body heat, stance, equilibrium and also sense the presence of other beings being far away from the target-that wasn't hard, basically all my 5 senses are more enchanted than a wolf, especially the smell of blood, I could 'feel' the blood of a target even kilometers away, also, my body control, balance and breath increased too to an inhuman level, I can see well in the dark too. But the most terrifiying thing Is spar with the old man, f*ck me, he's just inhumane, like wtf, every time to match me he blinds himself and uses only his legs...And I had to this every day, almost all the time for the day, for almost 10 years, I'm surprised I'm not just gone crazy. But compared to my demeanor in my previous life, I think I changed a lot, when I was on earth I used to walk slowly and have a slow pace, now it seems I'm running desperately if you could count the speed of my previous life, also, the old man told me about this habit of me to unconsciously hide my presence all the time, a thing I didn't noticed and said. "Isn't it boring? And you will scary Mary." He said, but, frankly, who cares. It's not like Mary could notice me even with my full presence...'

'I also discovered that my strength at night is not only 2x like the others vampires, but 4x! The only reason I came up was my darkness, it's an ability of the demon clan, and every demon has 2x strength at night just like the vampires, so the darkness is likely my only option...'

'I did not train my [absorption] skill too much, but I discovered I can absorb even the energy of the plants, the air, the ground and the rocks...etc, other than just living organisms, its just that the amount of energy is pitifully low...but I still use this skill all the time, as the time passes I will automatically absorb and gain power, even if its just small...Also, thanks to the decent amount of apprentices holy knights send to this forest for undeads notifications, I gained quite a power, and yes, my darkness can absorb it in place of my body, just one word, my darkness is: JustFuc*ingStrong. That was just a word wasn't it?'

'About the darkness, I didn't know I could use it like that..'
