One Piece: Unreal Adventure - Chapter 76: Tomorrow will be war

This is the story of a poor young man whose poverty even shreds apart their family willing to climb his way through society and into the top

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

Athen had always lived a solitary life, as without any family or friends, he struggled to survive in his poor, forgotten hometown. The only escape from this grim reality came in the form of tales of magic told by rare visitors from the distant capital.That was, until one day, Athen discovered that magic wasn't just a dream. It was within him.With his newfound power, Athen completed a desperate heist, stealing a priceless diamond. But his triumph was short-lived when he realized the diamond was a fake.Yet... what seemed like a cruel trick turned out to be a blessing in disguise, for the fake diamond held the key to unlocking Athen’s greatest desire: the chance to truly learn magic.

After his fall, the Duke who was distant with his wife and daughter recalled his memories of another world. With a new perspective on life, he swore to cherish and protect those two.
