After settling my memories, I laughed. I was weak in my two lives, but not in this lifetime. Suddenly, anger and killing intent took root in my mind.
I, Adrian Kaelthorn Ravenshade, was just an extra, a background character whose only job was to fight MC because of my fiancée and sister, and to be killed. My mind has calmed down. In this life, my only wish is to become the strongest. I don't care about them anymore, it is also my fault, as I look from the novel's perspective, I fought with mc, tried to kill him because of those who don't care about me.
I need to make plans for my future, and also, my birthday is 3 days later.
I need to leave this house. I don't want to live in this house anymore with that sister and parents who don't care about me.
I leave my room and start walking towards the dining room along the corridor, servants passing by looked quiet, but I can see they are looking down on me. I didn't say anything, just kept moving till I reached the dining room. I opened the door three people were sitting there.
My father, Duke Valerius Ravenshade, sitting beside him, my mother, Lady Seraphine Ravenshade, both SS ranks, and my sister Selene Ravenshade, D rank. I arrive and quietly sit down and start eating. After finishing, I returned to my room and started planning. There is still one year till the academy starts. I need to leave this house and start training outside as a mercenary.
Why mercenary and not adventurer? Because I can keep my identity hidden, as mercenary adventurers require identity verification. I need to give them a big surprise for my birthday. I am an F lowest rank in the nobility, and I need to quickly start training the Main character might be at D rank at this moment. I had called my butler, the only one who cared about me in my previous life, and I had talked about some arrangements and firmly ordered him not to tell my parents till my Birthday.
The world has changed since 2055, when mana was introduced in this world. Many earthquakes and floods, calamities, and disasters have almost killed half the population. The other half has survived and adapted to the mana in the atmosphere and their bodies, and evolved beyond and transcendent. We give them a level from G- to SS+ and with each level, they can live longer. In the A rank, 180 years, and in the S rank, 230 years, and SS level, they can live more than 300 years.
With Mana Differents, Species have also come to Earth, which includes Elves, Dwarves, DemiHumans, and Vampires. They each settled on Earth and made their Empires. In the early days, there were conflicts among them.
One Day, suddenly, the Demons who have destroyed the home planets of Elves, Dwarves, Vampires, and Demihumans and built their bases on those planets start attacking Everyone. This time, every species works in alliance against the Demons and defeats them. There have been many deaths of Heroes from everyone.
Their Overlord SSS rank can not come to this world, as there is a natural barrier made of some Mana to protect this planet, which is why they are trying to destroy this barrier from the inside with their Dark Mana. With each year, the barrier is thinning; in the next few years, it will be gone, and then we will have to fight the calamity named the overlord. This war is called The Eternal Concord.
To protect the world, Humans, Elves, Dwarves, Vampires, and demi-humans created the Nova Academy to train the Elite younger generation for the Future. There are many other academies there, because it is hard to pass the entry exam, even if you somehow pass, if you do not show progress, you will be kicked out.
