Mushoku: Born Among the Great Powers, I Conquer Eris

[Swordsmanship and Magic Training + Dual POV + Official Heroine Aisha + Harem of Anime Heroines + Invincible + Born Among the Strongest + Rudeus's Older Brother]

Sevian died suddenly after staying up all night to watch episode 13 of Mushoku Tensei Season 3, his emotions getting the better of him. He was then reincarnated in a different world of swords and magic.

But he unexpectedly discovered that he had been born three years before the protagonist, Rudeus, as Paul's eldest son.

He, Sevian, was Rudeus's older brother by three years, and had been born with power on par with the lowest-ranked of the Seven Great Powers!

In swordsmanship, at one year old, he could overpower a Sword King with one hand!

In magic, his talent rivaled Rudeus's!

But Sevian didn't reveal his strength too early, because behind the scenes, a god who loved a good show was watching the whole world, erasing anything that threatened it.

However, on top of being born among the strongest, Sevian also had a powerful System: the [Aisha Conquest System]!

As long as he raised Aisha's affection for him, he could gain even greater power and divine weapons, until he became the strongest of the Seven Great Powers!

So Sevian went straight ahead and treated Mushoku Tensei like a gal game!
