Ruiweld Superdia

My name is Ruiweld Superdia. I am a member of the Superd tribe of the Demon race.

I somehow reincarnated into this world of Mushoku Tensei. And as it seems I am the son of Ruijerd Superdia, a side character that everyone likes.

From my knowledge my fate is to end up getting killed by the frenzied Superd warriors by their cursed spears. I really don't want to die, so I started my own training since I'm still a child.

The Superds have tail on their back the moment they were born. They hardened and fall off when they mature a certain age and they can start their training as warriors.

I still have my tail on my back. I could control it voluntarily and it moves flowingly. They're still soft and flexible.

So I decided to start training physically. With my knowledge with all sorts of anime and manga, I trained in all sorts of methods used by them. There's also my knowledge of this world on how warriors use their mana to achieve superhuman physical abilities.

Training with weights and run until I collapse, meditation under a waterfall, physical training exercises, etc etc.

Year after year passed and I'm growing slow steady. For some reason, I could feel that my body is now getting wrapped with Battle Aura.

After years of years of training and meditation, I could finally sense my own Mana and use them to strengthen myself. That's when I get the idea to start using this Mana through my body.

I'm 3 years old this year, and I had just managed to wear Battle Aura. The main character Rudeus had already become an Intermediate mage at this age. I need to keep working hard so I won't lose.

...

Couple of years passed, and there's something big happening. I still continued training through this year's and I have grown bigger since then.

But because of it I was under in a situation.

I'm in the village chief's house. Where the Chief and the elders held their meetings and lead the Superd tribe. It's like the City Hall of our tribe.

I was accompanied by both my parents, Ruijerd and Luwelia Superdia.

"This sure is something."

"I never thought your tail would fall off this young."

"How old is he again?"

The chief and the five elders observed me and my tail that has just fallen off and became a spear.

"My child is only five years old." the one who answered is the man beside me, my father, Ruijerd Superdia.

"Five years old."

"He's still a bit too young to start training as a warrior at this age."

"What should we do?"

The elders openly discussed.

The norm for a Superd child to matura and their tails fall off is around 10-12 years old. Any younger than that is either someone sick or suffering with deformities and had to forcefully cut off their tail in order to survive.

I guessed that in the entire history of the Superd race, my case was unheard of.

Actually it was my fault. I got too carried away with my training.

One day I have a thought in my mind, 'What if I also use Mana on my tail?' and started actively pouring Mana in my tail. Mana grows bigger the more you use them and come back having bigger Mana capacity than before

The tail had turned out to be an excellent way to expend Mana as it absorbed it all greedily like a bottomless pit. So I got too excited and expended most of my Mana on my tail when I'm training.

And just like that it has proven to be a super effective method as in the next day my Mana has grown triple than yesterday. That's what happened in the first day.

I keep doing it every single day and my Mana grows bigger than what it was the day before and I was so excited. It's like I found a glitch in the game I could exploit to be super Overpowered.

And then one day when I was about to wake up and started again my training, my mother Luwelia shocked in horror when he saw my back without a tail.

Apparently it had fallen off when I was asleep.

Mother reported it to my father who worked as the Captain of the Warriors of the tribe. And then he reported it to the elders and here we are right now.

"I heard you were a strange child Ruiweld. You don't like to play with other children and can only be seen on your own with strange behavior." The chief said to me.

"Yes."

Did he mean where I occasionally sir down on the shade of a tree and meditate while doing Mana exercises? Doing some old physical calisthenics? Or putting on a blindfold to enhance my senses on my third eye? It could be anything.

"You have already matured with your soul became a spear, normally you should start your training right a away, but you're still very young. You can choose not to start your warrior training until you reach the normal age and train together with your peers. Or you can choose to start with your training immediately. What will you do?"

There's no holding back. I have already decided.

"I choose to start my training as a warrior."

"I see."

The chief accepted Ruiweld's choice. They began to discuss about the specific details.

In the end it was decided that my father, Ruijerd, will supervise my training. Even though he was busy as the chief warrior, training his own son wouldn't be a disturbance for him.
