The Science Ace Go Back To The Past To Save Her Brothers - Chapter 10

300 years after becoming a Demon King, the war angel Ansel faced a serious problem during a certain expedition.

——His halo grew out once again.

Ansel picked an auspicious place that was definitely and absolutely unmanned, and while cursing, he simply and skillfully broke off the newly emerged angelic aperture.

This thing was growing out faster and faster!

When will his undercover mission end already?!

The demon realm was divided and ruled by three kings. Demon King Saros was forced to go on an expedition with his sworn enemy, Ansel.

One day, he noticed Ansel sneaking away from everyone.

Saros decisively followed him, and was shocked to find that his sworn enemy, another demon king of the demon realm, took off a horn headband and fake bat wings. As Ansel cursed up and down, Saros watched as he skillfully removed a cute halo from his head.

This irritable, easily angered guy who loves fighting; the type that was cute when he shuts up but could make even demons angered to the point of ascending to heaven the moment he opens his mouth…

..was actually an angel???

- Description from Novelupdates

The most precious things in the world are priceless. Ordinary men tend to turn a blind eye to this fact. Apart from the treasured air, sunlight, and familial love, there is still one more thing that’s extremely valuable. It’s right beside you and can be easily obtained. But… I wonder whether you can see it?

Taking a quick peek into life on normal planet earth, a vicious alien race called the Xollante attacked the planet with their nuclear weapon. But that's not the story...Shortly before the alien attack, the story was based on an orphan boy named Leo Rayden who somehow discovered that he possessed interstellar communication ability. With this ability, he communicated with a being from a planet friendly with Earth. The being told him that he must warn earthlings of the attack from the Xollante race. But Leo saw himself too young and too weak to carry out this assignment. So, neglecting the warning, the Xollante finally arrived on Earth's atmosphere and just like that, Northern Earth became destroyed... The Space Guardians of Earth couldn't stand the almighty Xollante fleet.And to make matters worse, Earth's core became weak and split.But that is still not the story...A second era now was set in place after the nuclear attack. Earth became split from the core after the nuclear attack and slowly, the Northern and the Southern part of earth started drifting apart. The wild Xollante race occupied the North, while the surviving earthlings occupied the South.But now Earth must do everything to destroy the Xollante race and send them away from the planet. And that was when another scheme was set.Earth had discovered a Lone and barren mutant planet called Luxus which gifted earthlings with superpowers. Humans call these superpowers “Quirks”. So, for the grand scheme, Earth's authorities started sending men and women on the planet to become mutated in readiness for the huge war that was looming against the Xollante. Earth was now full of mutants, and soon enough, non-mutants became outcasts in the society. The system only favoured the powerful and scorned the weak. And that was when Leo woke from his coma of 78 years on planet Luxus.And this, guys, is where the story starts...Leo managed to survive the nuclear attack with some strange hidden quirk he didn't know he possessed. When he opened his eyes 78 years later, he was on planet Luxus, being taken care of by his mind communication partner, Loca. But there was no time to frolic. He has to get back to Earth and try to rediscover that powerful quirk that saved him from the nuclear attack. To do this, he must attend Earth's quirk academy to learn all he needs to get stronger. He knew somewhere within him lies the most powerful quirk ever in existence, and his only aim is to rediscover it. He must become stronger, beat earth's power system and one day help the top earth Avengers fight off the Xollante race.But first, he must overcome every obstacle thrown at him from his fellow Earthlings and fellow mutants before he could even think of fighting the aliens.He must attain the highest rank level possible to atone for his sin as a child for not saving Earth when he was informed.His guilt being the major drive, he soon found that the highest rank was within reach of him, but can be pay the price?This story incorporates the use of hi-tech weapons and ancient weapons, and the use of acquired quirks to wield these weapons to victory. It is truly a story about weak-to-strong, action, survival, mutants, adventure, academy and superpowers.A mix of sci-fi and fantasy, yes.And yes again, local beast weapons have been smuggled into sci-fi. Let's deal with it.

I’ve reincarnated as the reverse harem game’s villainess, the one and only step-daughter of the Eckart duke family.

But the difficulty just has to be the worst!

Everything I do will only lead me to death.

I must be paired with one of the main male characters from the heroine’s harem before the ‘real daughter’ of the duke family appears!

Two older brothers who always pick a fight with me on every little thing.

The insane crown prince whose route will always lead to my death.

‘I only see the heroine and no one else’s wizard, and also her loyal s*ave knight, too!

‘First, let’s take some of them which I see no hope in, out of the list!’

“I didn’t know my place up until now. From now on, I’ll live as quiet as a mouse so you wouldn’t care the slightest bit!

But why do their interests in me keep on rising every time I draw the line?!
