So let's start with my name being Alex and I'm 16, or was 16 before I died.
The strange thing is that I do not remember how I died, although I should.
Why do you think so? But because now I am in some kind of white room !!!
In my life I read a lot of stories about fellow travelers, so I was not really surprised.
And as I know, God should soon appear.
God: Hello Alex.
Alex: Hello ...
God: are you not surprised ??
Alex: not really.
God: Then I will say briefly. You are dead and transported to another world.
Alex: Oh cool ....
God: As I see you are an avid otaku so I'll let you choose the abilities from Anime.
Alex: Can I get into the world of some anime?
God: mm, not now, but in the future you can.
"So let me choose three abilities"-I'm said
God:but choose wisely, and then there was one fool who took a bunch of strong abilities but died because his body could not stand them.
Alex: Ok, I chose !!
"I'll probably take Chidori from Naruto, Tekkai from One Piece and the Flash step from Bleach."I'm said.
God: Good choice! (He said with a grin)
Well then good luck !! I will send you to a world called Exfolia. Good luck heh
Alex: (what a laugh?)
A white veil appeared in my eyes and I disappeared.
Meanwhile, the god also continued to stand still and began to laugh.
God: Your death offended the gods, let's see how you survive their persecution))
I think that the best choice would be:
Majin Buu body/physiology from [Dragon Ball Z]
Predator from [That Time I Got Reincarnated as a Slime]
Gluttony from [Berserk Of Gluttony]
Majin boo body would give him a body that can survive on any environment, even on space, it has natural affinity with any magic, turn others into candy, eternal life, eternal youth, shapeshifting and the ability to absorb others to learn skills, the ability to regenerate as long as a cell still exists.
Predator will give him skills even when he did not absorbed anyone, with predator he will be able to gain power and skills just by turning people into candy and eating then, no need to have a split personality or to be forcibly evolved into a version of "super buu", this skill will allow him to gain any power.
Gluttony has the side effect of making him hungry for battle, but every time he kills someone a percentage of that individual power goes to him, and Gluttony comes with a system that allow him to keep an eye on all his skills and attributes.
With this he has a perfect indestructible body, the power to steal any skill and have infinite growth.
what a dumb dumb. why not take 'A Knight does Not Die With Empty Hand'.
